ACADEMIC EXPERIENCE
Visiting Scholar, University of California at Berkeley (UCB), February 2003 – January 2004
•
•
•
•
Participated in UCB research in digitally controlled converters
Performed research work in fault tolerance within the field of digital controllers and microprocessors
Developed optimization techniques for future power systems
Designed single point failure free DC-DC power systems
Teaching, Technical University of Denmark, August 1998 – December 2001
Gave lectures on most aspects of modern electronics ranging from introductory courses in analog circuit
design to advanced control principles in power electronics. The teaching activities provided a valuable
training in public speaking – a very useful skill when presenting papers at international conferences.
Digitally Controlled Buck Converter, 2002
Developed and implemented a low power buck converter, controlled by two different control laws, using
a low cost microcontroller. The level of ‘intelligence’ provided by the microcontroller allowed for
successful implementation of the concept of analytical redundancy, which in turn improved the overall
system reliability. This work led to a paper submitted to Power Electronics Specialists Conference 2003
where it was accepted for presentation in June 2003.
Switching Power Amplifier, 2000
Designed and implemented a switching amplifier for electromagnetic wave generation. Due to very low
harmonic distortion requirements the amplifier was implemented using a Multi Enhanced Cascade
Control approach that ensured simultaneous feedback to multiple control parameters within the system.
Pole-zero cancellation in the feedback and forward signal paths of the amplifier allowed for transfer
function shaping.
Switch Mode Power Supply for Autonomous Robot, 1999
Developed multiple outputs DC-DC switching power supply for portable navigation computer system.
Due to limited Printed Circuit Board (PCB) area the power supply was implemented as a very high
density power supply using PCB traces for cooling.
