Even after the success of Brussels, Grenoble, Aachen, Florence, Brighton and Sevilla, this EPE conference will offer you more. A record number of synopses have been received (more than 950), where the increase from industry is especially significant and has encouraged us to work very hard in organising numerous new activities and events. These will give each EPE conference participant the feeling of being the right person in the right place. We have also accepted a record number of papers, 733. I am proud to present this detailed programme for what promises to be a highly-successful conference. Think of the motto: "Power Electronics for Sustainable Growth". These are no empty words. This is really what we are aiming at. The technical programme is full of results directed towards that goal: energy savings, rational and safe use of energy, new energy sources, renewable energy systems, EMC, electric and hybrid vehicles, locomotives to mention only a few of the obvious topics. The opening and keynote sessions will be newsworthy. Mr Odd H. Hoelsæter, president & CEO of Statnett will explain his view on the evolution of energy supplies in Europe. Norway is the second-largest oil exporting country in the world (only after Saudi Arabia): In our sector, three newHVDC connections will be built between Norway and the continent. This will be a huge investment that surely will have important consequences on our future. If you turn to page 22, you can see other topics that will be presented: Integration of power components, what will change in our daily work? New areas of applications for power electronics: you will be challenged by the authors. The electric vehicle; a silent revolution, however an exploding technology. But this was not enough! We wanted more from this conference, so, we are organising a competition. The topic? To write an essay on either "How to Teach Power Electronics for Sustainable Growth" or "How to Develop New Power Electronics Products to Promote Sustainable Growth". The prize? NOK 6.666 and a publication in the EPE Journal. More details are given on page 9, so gather your best ideas. Since we are organising this competition, Gro Harlem Brundland, our former Prime Minister, decided to patronize the Conference. Gro Harlem Brundland has been head of the World Commission on Environment and Development and she hopes that our initiative will spread and open new horizons. In the UN-report "Our Common Future" it is strongly recommended that the ideas agreed on in the report should be taught in universities all over the world. Please send the information about the competition to your power electronics colleagues, especially the younger ones, all over the world. You might influence the future! Before the conference, there will be 11 tutorials where all the new, hot topics will be taught. Nine will be on the NTNU campus on 6 and 7 September. Those who register will get the written documentation from all the tutorials and will be allowed to move from one tutorial to another. We are most enthusiastic about the two tutorials on "High power Motor Drives" and "UPSs" which will start by touring the Troll Gas Terminal at Kollsnes close to Bergen and continue on the newest coastal express ship (built in 1996). These tutorials will be combined with a cruise of the west coast of Norway and the ship arrives in Trondheim on Monday morning 8 Sept. a few hours before the conference starts! Do you want to hear more? There is a lot to say: The exhibition will be greatly extended. We expect more than 50 exhibitors (there is room for 100 and we will work hard to get 100). The area for the exhibition will be much more integrated in the conference than before, with coffee-serving included in the same area. For the first time, there will be several product presentations by exhibitors; these will be presented before an informal meal on Sunday 7 September in the evening, which is combined with the opening of the exhibition in the evening. Further, a lot of Discussion Sessions will be organisedat at the end of the Dialogue Sessions. The new developments in power switches will be throughly discussed and include themes like: "Application Specific Power Modules", "The Relationship Between Product Developers and Device Manufacturers", "High Power Integration", "Smart Power - in various applications", "Impacts of Integration" and "GTOs versus IGBTs". After the conference, on Thursday 11 September there will be three Post-Conference Technical Visits. 1) A typical Norwegian hydropower plant with the generators inside the mountain. The station is within the city limits of Trondheim (!) and is owned by Trondheim Power Utility. 2) Siemens power electronics factory and a converter station feeding the 16 2/3 Hz for the Norwegian State Railways. 3) ADtranz charter train to the Stømmen factory close to Oslo. We will learn about the new tilting trains that the Norwegian State Railways has ordered. At the factory there will be a press conference where a new train will be presented. The attraction to get the press there will be increased by our presence. ADtranz will provide buses for a one hour drive to Oslo airport. So, those who start at Kollsnes close to Bergen and return from Oslo after the train trip across mountain plateaus and glaciated valleys must sign up fast. First come, first served. There is a special offer from SAS for the air-ticket. We have worked hard. But with the expected success, it is a pleasure for us to welcome you to the EPE '97 conference in Trondheim. At the end I will like to mention how enthusiastic ABB and other Norwegian and Danish companies have generously sponsored the conference, so the fee to participate is the same as in Seville in 1995! The companies are listed in the provisional programme, and you will learn more from those companies at the conference and by looking at our WWW (http://www.elkraft.unit.no/epe97/).

It was the country's first capital city (until 1217). Trondheim is located by one of the largest fjords of Norway with the salmon river Nidelven running through its centre. Today the city has close to 150000 inhabitants and its total area is 342 square km. The city is an administration, business and technology centre in a rich agricultural area surrounding the Trondheim fjord. It is a university city and has Norway's most advanced research community in science and technology. During the whole millenium year of 1997, there will be numerous special events such as The World Ski Championships in February/March, and the combined 60th birthday celebration of our King and Queen in June, where royalty from most of the European royal families will attend. A map of the city is enclosed. References to places shown on the map are put in the text. One cm on this map is about 140 m. Weather Normally the weather is pleasant in Trondheim in September. The temperature may vary between 10-15 degrees C. Rainy days may occur, and we recommend appropriate shoes and clothing, since some events in the social programme will take place outdoors. Travel There are frequent domestic flights between Trondheim and the international airports in Oslo, Bergen and Stavanger. Flying time between Oslo and Trondheim is 45 minutes. There are approximately 27 departures from Oslo to Trondheim daily. There are two daily direct flights between Copenhagen and Trondheim. SAS (Scandinavian Airlines Systems) is the official carrier of the congress. Please state the reference number "NO 9701" when you make your flight reservation at a SAS travel agency, and you will obtain a discount price. Travelling by train within Norway gives an excellent opportunity for sightseeing, and Norwegian trains are of a high standard. The train journey over the mountains from Oslo to Trondheim takes approximately 7 hours. There are four departures from Oslo to Trondheim daily. An interesting alternative is to travel by coastal express boat from Bergen to Trondheim, a journey of approximately 30 hours along the rugged Norwegian coastline (see pre-conference tours). Your travel agent, or any SAS travel agency, can supply you with full details on travel to Trondheim. An APEX air ticket allows transfer to one city in a country, for instance Bergen, and return from another city in the same country, for instance Trondheim or Oslo.

Let us recommend a few possibilities: - a stay in Bergen, including the one day trip "Norway in a nutshell" - a stay in Oslo, visiting the most popular attractions of the capital city - an extended stay in Trondheim and the area around. Røros is a very nice place to visit (see accompanying persons programme and pre conference tour) - a tour with the Coastal Express, Hurtigruten: the presented pre-conference tour from Bergen, or a tour from Trondheim further south to Bergen or north to Lofoten or all the way to Kirkenes For ordering tickets in or to Norway you may contact the travel agency (refer to the EPE conference): Flyspesialisten SIT reiser Attention: Bjørn Berg Phone: +47 73 59 67 44 Fax: +47 73 59 26 35 For further tourist information contact Norway's Information Centre: Vestbaneplassen 1, N-0250 Oslo, Phone +47 22 83 00 50, Fax: +47 22 83 81 50 Oslo (http://www.leoburnett.no/nortrameny/nortra.html) Adventure, natural scenery, art, architecture and philosophy are a few of the things you can experience in Oslo - the capital city of Norway. Oslo's city centre is compact, most of the hotels, museums, entertainments and shops are within walking distance. Oslo can offer some 50 museums and many art galleries. Amongst the internationally known attractions are: the Vigeland Park, the Viking Ships Museum, the Kon-Tiki, the Fram Museum, the National Gallery, the Norwegian Folk Museum, the Munch Museum, and Holmenkollen. Bergen (http://www.uib.no/guide/) Bergen is a charming harbour city located between seven mountains. It was a German Hansa Stadt. Bergen is worth a stay itself, and it offers a convenient starting point for the tourist to begin to visit the famous fjords of Norway. Tourist office: Phone: +47 55 32 14 80 Norway in a nutshell (http://www.uib.no/guide/bergen-tours.html) This unique and popular day-excursion takes you through some of the most magnificent scenery to be found on the west coast of Norway. You leave Bergen by train in the morning, along the beautiful Sørfjorden to the town of Voss. From there, you start to climb to the great mountain plateau which separates the western fjords from East Norway. In Myrdal, you change trains and then go down the many sharp curves on the famous Flåm Railway which has a reputation for one of the most spectacular train rides in the world. You will pass by lofty, snow-capped mountains, thundering waterfalls and peaceful green meadows on your way to the valley below. After a lunch stop in Flåm, the trip continues by boat on the Aurlandfjord and Nærøyfjord, one of the narrowest fjords in Western Norway. From the town of Gudvangen you will go on by bus to Voss where there is a train waiting for you to take you back to Bergen. Departure Bergen at 8.50 (return 18.50) and 10.20 (return 20.20). Price: NOK 470 The costal express - Hurtigruten (http://www.monet.no/hr/) The World's Most Beautiful Voyage is a voyage like no other. Nothing can compare with it. Nothing about this journey will resemble anything you have ever experienced before. A ticket for the Coastal Express is a ticket to the theatre, an 11-day drama, from Bergen to Kirkenes and back, in which new acts constantly unfold all around you. The World's Most Beautiful Voyage offers a unique combination of peace of mind, comfort, and service on board, coupled with constantly renewed impressions of the scenery through which you sail and the harbours you visit. You will witness tender goodbyes on the quayside next to forklifts loaded with cargo. See simple, weather-beaten villages where you wouldn't have thought it possible that anyone could live. Discover sheltered, charming fishing villages under the Midnight Sun in the summer, and the spectacular night skies with dancing veils of Northern Lights in the winter. And in large towns like Bergen, Trondheim and Tromsø, you will find art and culture, tourist attractions and shopping to satisfy your every need. Trondheim (http://www.aksess.no/trondheim/tourist/) In Trondheim you can see: - Nidaros Cathedral - see Social programme: Concert and reception - The Archbishop's Palace - see Social programme: Concert and reception - Stiftsgården - see Accompanying persons programme: Go for a stroll I - The Tyholt Tower - see Accompanying persons programme: Sightseeing in Trondheim - The Wharves - The oldest of the wharves along the River Nidelva date back to the 18th century, nevertheless they still give the impression of the waterfront as it was long before then. On the seafront, towards the canal, we find wharves that were built more recently, in the 19th and 20th centuries. Lofoten (http://home.sn.no/~perkaa/) Lofoten is the archipelago to the west in the ocean, north of the Artic Circle, at the 67th and 68th degree parallels. Lofoten stretches like a wall of moutains to the southwest in the sea. Between the mainland and the "Lofoten Wall" lies Vestfjord. Lofoten consists of mountains and peaks, wide open ocean, sheltered inlets, stretches of seashore and large virgin areas. The principal islands are Austvågøy, Gimsøy, Vestvågøy, Flakstadøy, Moskenesøy, Værøy and Røst. The total land area amounts to 1,227 sq.km. About 24,500 people live there. The road distance is almost 170 km from Fiskebø near Vesterålen in the north to Å in the south, where the E10 ends. From Lofotodden, at the south end of Moskenesøy Island, the air distance is more than 60 km to Skomvær, the southernmost point in Lofoten.

Adjustable speed a.c. motor drives, applications by P. Enjeti, F. Blaabjerg and J. K. Pedersen. Summary Adjustable speed a.c. drives have become the preferred choice in many industrial applications where controlled speed is required. At the availability of fast solid state power semiconductor switches (IGBTs) has resulted in voltage source, PWM controlled inverters becoming a standard configuration in the power range to 500 kW. While high frequency PWM control represents the most advanced drive concept, when inappropriately applied, it also generates side effects, some of which have been recognized only recently. This course present a comprehensive coverage of application issues of PWM inverter controlled a.c. motor drives which include: selection criteria for energy savings, increased motor losses: damage to motor insulation due to reflected voltages caused by long motor leads, acoustic noise problems and solutions for sensor-reduction. Following a description of the problems, several practical solutions are also presented and nanlysed. Finally, line harmonic problems caused by the input diode rectifier are also described and several low cost solutions selected to meet IEEE 519-1992 are presented. Basic content Introduction to ASDs, application problems and energy savings; Introduction of application problems to high dv/dt and long motor leads; Filter configurations to minimize the motor winding stresses due to high dv/dt; Application problems due to high dv/dt - continued; Acoustic noise problems and their reduction; Reduced sensing technique in ASD and their problems; Power quality compliance of ASD equipment. The audience PWM inverter/motor manufacturers, system designers as well as adjustable speed drive application engineers and users will find this course informative and beneficial.

Then, after a short overview of Matlab/Simulink, various industrial application examples in the fields of power electronics and mechatronics are described. The first example is a step up-down converter. The mechatronics applications are: simulation of a pseudo-linear system (friction and stiction), frequency-voltage control of an induction motor, vector control of an induction motor, wrist stiffening of a bilateral Master-Slave force reflecting servomanipulator, control of articulated boom of JET (Joint European Torus) and finally, active control of an electromagnetic suspension system. For each application example, the teaching includes a theoretical part (modeling, control design) followed by the validation on a PC. As a conclusion, general design methodologies are outlined and advantages and drawbacks of Matlab/Simulink are summarised. Contents General considerations on the numerical simulation - Modelling - Integration algorithms - Quantization and numerical problems Overview of Matlab/Simulink - Building blocks - M-files and MEX-files - Simulation algorithms and step size control - How Simulink works Applications - Set up-down (Buck-Boost) converter - Simulation of a pseudo-linear system - Frequency-voltage control of an induction motor - Vector control of an induction motor - Wrist stiffening of a bilateral Master-Slave force reflecting servomanipulator - Control of an articulated Boom of JET - Active control of an electromagnetic suspension system Intended for: design engineers, industry applicationengineers, reserchers Course Faculty: Dr. Silvio Colombi, Laboratoire d'Electronique Industrielle, Ecole Polytechnique de Lausanne, Switzerland T6: Application of fuzzy logic and neural network techniques to modern electrical drives by P.

Understanding and complying with CISPR and IEC 1000 Standards on EMC by A. Zuccato, L. Rossetto. Since January 1996, electrical and electronic equipment sold in the European market must bear the CE mark which attests compliance to EMC standards, which take into account both radiated and conducted noises in a very wide frequency range (up to 1 GHz) and require several emission and immunity tests (including electrostatic discharge, fast transients, surge voltages etc.). The first part of the tutorial reviews the standards regarding low-frequency emission and immunity to line disturbances, and in particular IEC 1000-3-2 which limits the low-frequency harmonic distortion (from 50 to 2000 Hz) of equipment with rated current less than 16 A per phase. Common problems and misunderstandings in applying the norms are addressed and operational experience is reported for various families of industrial and domestic loads. Then, basic passive and active power factor correction techniques are illustrated and compared. The second part of the tutorial reviews CISPR and IEC standards regarding conducted and radiated noise emission and immunity. Typical problems arising from their application are discussed from a practical point of view and mitigation guidelines are given. Lastly, the design of a power factor corrector circuit complying with all the above standards is illustrated.

Keynote 1: Monday: 14:00 to 14:45 Integration of power components, state of the art and trends, by André A. Jaecklin, ABB, K. Rischmüller, SGS-Thomson Microelectronics and Leo Lorenz, Siemens Part 1 by A. Jaecklin The field of high power applications has recently experienced a strong push from advances in device development. On one hand, Insulated Gate Bipolar Transistors (IGBT) in the form of hybrid modules are continuously increasing their limits in current („ 1500 A) and voltage (up to 4500 V). In the highly demanding market of traction applications, reliability has become on of the crucial issues, however. On the other hand, based on the classical Gate-Turn-Off thyristor (GTO), a new element has been conceived, called the Integrated Gate Commutated Switch (IGCT). This device implies a rigourously reduced leakage inductance combined with a gate drive unit implemented into the structure. Applying a hard gate drive (hard driven GTO) opens the way to high voltages (> 10 kV) by means of multiple series connection as well as to reduced losses due to snubberless operation. Essentially, these two approaches are complementary. Part 2 by K. Rischmüller This part was not available by the time of printing Part 3 by L. Lorenz Power semiconductor components, including their further development as monolithic power ICs, and hybrid system integration are the driving forces behind advances in power electronics systems, particularly with regard to energy savings, improved control response, noise redustion, size and weight reduction and cost minimization. The first attempt at hybrid integration was the implementation of IPM's, ASIPM's and PIM's. The PIMs and ASIPMs currently known consists of a package containing all the power switches including brake chopper with drive/protection circuitry. However, today's IPMs, ASIPMs have several advantages concerning interface, cost and system requirements. As a result of all these disadvantages, these solutions have no future and will be superseded by system integration in the medium term. This paper highlights the new approaches to system integration based on chip level. The authors: André A. Jaecklin is Head of Basic Development with ABB Semiconductors. He is also Titular Professor at the Swiss Federal Institute of Technology K. Rischmüller was head of application systems with Sescosem, after Thomson Semiconductors and is currently with SGS-Thomson Microelectronics. He is author of numerous application notes on power semiconductor devices. Leo Lorenz is involved in the development of power semiconductors with Siemens in Munich. For 10 years he is in a management position in several areas of power semiconductors . Tuesday 14:00 to 14:30 Needs for solutions and new areas of applications for power electronics by Prof. Lars Gertmar, ABB Corporate Research and Lund Institute of Technology The keynote speech will partly serve as a visitor',s guide for the delegates. Based on available information on EPE'97 papers and some previous ones, some of the achievements will highlighted as specific examples and as an introduction to the two following sections of the speech. The second part will cover the trends in some societies and the potential applications of the power electronics in Transmission & Distribution, T&D and Adjustable-Speed Drives, ASDs. There are challenges to generate electrical power from various sources to transmit & distribute power as well as to save energy. The competition between electromechanics and power electronics will also be a subject as well as hybrid solutions, especially in T&D. Finally, the author hope to challenge the audience to focus their future work not only on incremental steps on existing and nearby technologies but also on paradigm shifts towards compact, light-weight, easy-to-install, low-emission, compatible and sustainable solutions based on power electronic s.

The state of California has defined by law an introduction programme imposing 10 % sales of electric vehicles by 2003 and 25% of hybrid vehicles i.e. a market of respectfully 300.000 electric and 750.000 hybrid vehicles. Other states are following the same regulations. In Europe, countries such as France, Switzerland, Sweden, Belgium, ... are also demonstrating big interest through a number of programmes going from pure market penetration up to R&D activities. Japanese car manufacturers seems to engage a competitive action against the american 'big three" colleagues. In such a contest, it is clear that technology has reached a high grade of maturity but undergoes in the same time a rapid evolution. The scope of this keynote is to describe and discuss the state of the art in the field of motorisation, power electronics, converters, charging infrastructure and surely batteries and all types of energy sources for hybrid vehicles.

Carrasco, Assistant Professor of Power Electronics at the University of Valencia Topic: The aim of the discussion will be to explore the needs of the users of power electronics related to active components, passive components as well as the specification of the components and other requirements as standardisation, regulations etc... in order to make a list of "wishes" and to find out what manufacturers can provide from this list of wishes. High power integration, Animator: Prof. André A. Jaecklin, ABB Corporate Research, Secretary: Dr. Stefan Linder, ABB Semiconductors Topics: a. IGBT: - module construction (e.g. high frequency design) - high voltage devices - high current devices (large scale parallel connection) - reliability problems (partial discharge; testing methods) b.

The power integration is coming slowly, because there are a lot of specific problems in power (Thermal, current density, mutual component interaction, cost, etcŠ), but will arrive in the market. What could be the consequences in power electronics. GTO or IGBT Animators: Jean Marie Peter, SEE and Consulting; Prof. Philippe Lataire, Vrije Universiteit Brussel A lot of progresses have been done in the field of high power IGBT. This component is now from 200 kW to several Megawatts a useful device. A big progress has already been done with the hard driven GTO called GCT. What are the main advantages and disadvantages of each components, what could be the optimal application field? Teaching Animator: Dr. Richard Duke, University of Canterbury, New Zealand The occasion of EPE brings the rare opportunity for international comparisons of power electronics educational systems. Each country of group of closely associated countries has developped its own unique educational system and power electronics education has developed and flourished in different ways to meet varying needs. What position does (should) power electronics hold in the undergraduate (graduate) programme? Should power electronics be a required course for all EE's, for all EE's specialising in power or is an elective arrangement more appropriate? There is a commonly held perception that power electronics education is often inadequate, especially with respect to practical experience in instructional laboratories. Should lectures and laboratories be an integrated package or are separate laboratory courses more appropriate? Are the traditional electrical machnies courses still appropriate or should there be more effort to integrate power electronics into such courses? To initiate discussion of these question, and others, some brief results from international survey of power electronics education in Australasian and North American Universities will be presented. Software Packages and Experiences in Simulating Power Electronics and Motor Drives Animators: Prof. Ned Mohan, Dept. of Electrical Engineering, Univ. of Minnesota, Minneapolis, USA; Prof. Eisuke Masada, Tokyo University In this discussion group, capabilities of various simulation packages will be presented for modeling of power electronics and motor drives.

POST CONFERENCE TRIPS Post Conference Technical Trips 1. Visit at Hydroelectric power stations In the river Nidelva, which runs through the city of Trondheim, the energy company Trondheim Energiverk (TEV) operate seven of its hydroelectric power stations. A technical tour to two of these stations will be arranged. Although the river is regulated for hydroelectric power production it is considered as one of Norway's best fishing sites of Salmon with a record of catch-up of up to 1 ton per km/year along the stretch where fishing is allowed. Nedre Leirfoss is a power station which was put into operation in 1910. The installed capacity is 12 MW and the average production is 67 GWh/year. TEV has a small museum at Nedre Leirfossen which shows the evolution of the technology at their power stations from 1910 until today. The Brattsberg power station is a typical example of the new generation Norwegian power stations and was put in operation in 1977. It is located inside the mountain and water is led through tunnels (not pipe-lines) to the turbines. The installed capacity is 120 MW and the average production is 600 GWh/year. The participants will be picked up by bus in the centre of Trondheim at 10.00 on Thursday 11 Sept. A light lunch will be provided at Brattsberg Power station. After the visit, at 13.00, the participants will be transported directly to Trondheim Airport, Værnes, by bus. Fee for the tour: 100 NOK 2. Visiting Siemens A/S, Trondheim, Siemens A/S is a worldwide company with sites in 181 countries. Siemens A/S was established in Trondheim since 1908. For the time being Siemens has 2750 employees in Norway and 830 out of these are in Trondheim. Siemens A/S in Trondheim has two factories. One produces electric heaters and the other produces middle voltage equipment, motor control cubicles and power electronic circuits. Siemens A/S power electronics department is in Trondheim. This department is a competence centre for power electronics in Siemens A/S. The Power Electronics department is specialised in UPS, rectifiers for aluminium industry and converters for railway power supply. On this visit to Siemens A/S here in Trondheim you will get the opportunity to get a presentation of Siemens A/S in Trondheim especially the Power Electronics Department and to visit the factory. After lunch there will be a guided tour to Stavne converter station which as 2 MVA, 16 2/3 Hz converter for railway power supply. Siemens A/S was the contractor to this converter station. The bus will collect you at Trondheim centre at 09:00 and return at 14:00 to Trondheim Airport, Værnes. Fee for the tour: 100 NOK 3. Train trip to Adtranz near Oslo Adtranz is organizing transportation from Trondheim to Oslo by train. We start in Trondheim about 8.00 in the morning, then we will pass the mountain plateaus and see the glaciers in full daylight. There will be a draw, one of our guests will be invited to stay in the locomotive from Oppdal to Dombås. This is over the largest mountain plateau, where also the speed is fastest. We will present our locomotives in the train as we go along with emphasis on the EL 18 locomotive of our train. Of couse we will tell a lot about the tilting trains. We just got one order of16 (!) trains to the Norwegians State Railways of one Billion NOK. In Norway straight rails are rare, 80% of the distance is a curve. So tilting trains is the only way to increase the speed. There is not enough trafic to allow for new railways. We will serve coffee and later on lunch in the train. The first EL 18 locomotive was delivered from the Strømmen factory of Adtranz Norway in the Summer of 1996. It is the first of a series of 22 locomotives, all will be made before 1998. Both passengers and goods will be pulled by these new locomotives, and a lot of more than 30 years old locomotives will be replaced. EL 18 is a Norwegian modified version of the Loc 2000 family. The specifications of the Norwegian State Railways are among the strictest in the world due to rough weather, temperature extreemes and blowing snow particles. In addition there are problems with condensation in the long tunnels. The locomotive is made with welded steel and some copper to avoid rust. The cabin for the engineer is made with a low weight glasfibre sandwich design. The boggies are radial controlled and follow the rails with low friction, better utilization of the traction power and less wear of the wheels and the rails than the older locomotives. Robust induction motors controlled by GTO voltage source inverters are Adtranz standard technology. Also the rectifier converters are like this, providing four quadrant sinusoidal 16 2/3 Hz input current. The maximum power at the wheels is 5.88 MW and the maximum speed is 200 km/hour. The train will stop close to the Strømmen factory just outside Oslo, at about 14:40. There we will invite you to a special press conference where we will disclose a new train! Our international EPE '97 guests will improve the atmosphere of the presentation, so we will both benefit from this. We will provide buses for you that will drive you from Strømmen through Oslo downtown to the airport. You will arrive at the Oslo airport Fornebu at about 17:00. Fee for the tour including train ticket and bus in Oslo: 420 NOK LECTURE SESSIONS The papers listed hereunder are those provisionally accepted for lecture sessions. Those papers will be submitted to further reviewing by the session chairmen and topic chairmen and the final programme of the lecture sessions will be chosen among the papers listed hereunder.
