Description

High Frequency Switching Converters, Multi-switch forward converters, Converter Modelling and Control, HF magnetics design, Snubbers, EMI and Thermal management, Semiconductor switch properties, resonant converters, induction machine properties, drives, starters and control, multi-level converters.

Building modern Power Electronic circuits is a complex task.  It involves analysis of the electro-mechanical system within which a circuit is embedded, followed by selection of appropriate circuit configurations.  Electric circuit, magnetic circuit and control design are all integral to sound system operation.  This course covers switching circuits for a range of powers and applications.  It covers circuits and thermal management needed to maximise efficiency and reliability, and meet EMC requirements.  Three phase system modelling, to enable model-based control of motion control systems, is included.  Students will learn how to design a modern power electronic system within the context of a power supply or motion control system.  It has a significant group project implementing an electric go-cart control system.

Topics covered:

Circuits:
- Revision of buck and boost converters.  Flyback and Cuk converters.
- Isolated forward converters.
- Multiple switch forward converters.
- Resonant converters.
- Layout and EMI/EMC
- Snubbers.
- Managing heat.
- Three phase and Multilevel converters.
Modelling and Control:
- State-space modelling of converters.
- Power converter feedback compensation.
- Current mode control.
- Motor control.
- Induction machines.
- Space vectors and vector control.
- Space Vector PWM.

Learning Outcomes

At the end of this course, the student will be able to:
1. Understand and analyse a range of power electronic circuit configurations
