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.
