Description including Unit Aims

This unit introduces advanced power electronics design techniques for modern electrical power conversion systems. The course begins with the modelling of power electronics converters (e.g. dc-dc converters and three-phase converters), based on which, a general closed-loop control design method will be developed following a frequency domain analysis. Various converter topologies (for example, voltage source converters, current source converters and multi-level converters) will be analysed using advanced modelling techniques. Hardware design issues in power electronic converters will be addressed in detail. Design techniques will be investigated for both standard and advanced (for example, integrated) magnetic components. Synchronous rectification techniques, resonant gate driver circuits and emerging power semiconductor technologies such as state-of-the-art silicon carbide devices will be covered. Practical skills such as the use of simulation tools (MATLAB/Simulink) and printed circuit board (PCB) design will also be covered with examples. The unit builds on previous Yr 2 and Yr3 electromechanical energy conversion courses (EENG27000, EENG28070 and EENG37000).

Teaching Information

Teaching will be delivered through a combination of synchronous and asynchronous sessions, including lectures, practical activities supported by drop-in sessions, problem sheets and self-directed exercises.

Assessment Information

2 pieces of coursework: 70% and 30% each of the final mark

Resources

If this unit has a Resource List, you will normally find a link to it in the Blackboard area for the unit. Sometimes there will be a separate link for each weekly topic.

If you are unable to access a list through Blackboard, you can also find it via the Resource Lists homepage. Search for the list by the unit name or code (e.g. EENGM0001).

How much time the unit requires
Each credit equates to 10 hours of total student input. For example a 20 credit unit will take you 200 hours of study to complete. Your total learning time is made up of contact time, directed learning tasks, independent learning and assessment activity.

See the Faculty workload statement relating to this unit for more information.

Assessment
The Board of Examiners will consider all cases where students have failed or not completed the assessments required for credit. The Board considers each student's outcomes across all the units which contribute to each year's programme of study. If you have self-certificated your absence from an assessment, you will normally be required to complete it the next time it runs (this is usually in the next assessment period).
The Board of Examiners will take into account any extenuating circumstances and operates within the Regulations and Code of Practice for Taught Programmes.
