AIM OF THIS MODULE
i)
To provide students with an understanding of the fundamentals of aircraft
electrical power characteristics and secondary power sources.
ii)
To provide students with an understanding of power electronics components and
circuits.
iii)
To give students an appreciation of conventional and more complex converter
circuits for aircraft applications.
iv)
To familiarise students with general knowledge of various components of avionics
electrical drive topologies.
BY ENGAGING SUCCESSFULLY WITH THIS MODULE YOU WILL BE ABLE TO:
i)
Select appropriate power electronics devices for converters application, taking into
account principles of device operation, device ratings, switching speed,
commutation requirements, and economic constraints.
ii)
Identify the features of aircraft electrical drives and associated power electronic
circuits and apply knowledge of their characteristics to the selection of appropriate
types.
iii)
Use design theories of various converter topologies.
iv)
Use thermal impedance techniques to select heat sinks for specified devices in
given applications.
v)
Safely perform and evaluate experimental work under supervision and present the
results in written or oral form.
THESE ARE EXAMPLES OF THE CONTENT OF THE MODULE
Characteristics of aircraft electrical power:
Aircraft electrical energy, requirements, typical types and rating, elements of aircraft
electrical drives, types and nature of aircraft electromechanical machines.
Power electronics devices characteristics, selection and protection:
Introduction to device operation, characteristics and ratings for FET, IGBT, SCR,GTO.
Safe operating area and triggering requirements.
Rectifier circuits analysis:
Study of half-wave and full-wave rectification and phase-controlled rectifier circuits.
Controlled and uncontrolled rectifier circuits analysed with various loads combining
resistances, inductances, and DC voltage sources. Three phase regulated and
unregulated rectification circuits for aircraft applications.
DC-DC conversions:
Principles of converter circuit analysis, study of major converter circuit configurations
like buck, boost, buck-boost. Identification of aircraft converter circuits, design for
minimum continuous current and minimum ripple voltage specifications.
Thermal calculations of power electronics devices:
Study of losses in PE devices, calculations of steady state switching losses and
conduction losses, interpretation of losses data sheets, thermal equivalent circuits, and
thermal calculations.
4.
THESE ARE THE MAIN WAYS YOU WILL BE SUPPORTED IN YOUR LEARNING TO
ACHIEVE THESE OUTCOMES
Students will be supported by lectures, tutorials and laboratories. Further directed study
will be supported by printed notes and guided reading. Material will also be available for
CBL via Blackboard/SHUspace. The laboratory sessions will include both hardware
experiments and the use of a specialised computer software environment. The typical
balance of contact time will be:
Lecture / Tutorial
70%
Laboratory
30%
5.
THESE ARE THE WAYS THAT WILL BE USED TO ENABLE YOU TO
DEMONSTRATE YOU HAVE MET THE LEARNING OUTCOMES
Students will acquire learning through a combination of lectures, tutorials, small group
laboratory practical periods, skills demonstrations and directed study material.
The assessment for this module will be 100% course work.
The course work assessments will be typically based on three routine lab reports in
which students will undertake laboratory experiments in groups, but must produce
individual reports, and one assignment based on aircraft converter topologies.

In order to achieve a pass in this module, students will demonstrate evidence of:
6.
i)
Ability to select appropriate power electronics devices for converters application
ii)
Understanding of the operation of a common type of single phase and three phase
rectifiers and the ability to design such rectifiers.
iii)
Ability to design basic dc-dc converter and interpret the result to obtain an
acceptably accurate performance.
iv)
Ability to estimate steady state switching and operating losses of converter circuits
and develop thermal equivalent model to estimate converter thermal state.
v)
An appreciation of the general converter topologies for typical aircraft applications.
THIS IS HOW YOU WILL BE GIVEN FEEDBACK ON YOUR PERFORMANCE
All summative assessment (except for the examination) is also formative, in that full
feedback is given regarding performance within two weeks of submission. Further
formative feedback is given directly during all the tutorial and laboratory sessions.
