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.
At the end of this course, the student will be able to:1. Understand and analyse a range of power electronic circuit configurations2. Understand real semiconductor switch properties, and how to manage them3. Understand and design thermal management systems4. Understand EMC requirements5. Model power electronic systems for control design6. Understand space vector three phase control principles7. Design and build a modern high-power dc/dc converter control system.
