Description

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).
