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:

Revision of buck and boost converters.  Flyback and Cuk converters.
Isolated forward converters.  
Multiple switch forward converters
Resonant converters.
Layout and EMI/EMC
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 conclusion of this course you should be able to:
  • LO1: Appreciate the applications and limitations of components and topologies used in power electronic systems (WA1, WA2)

  • LO2: Develop knowledge about, design, and analyse the performance of a range of power electronic circuit configurations, accounting for electromagnetic compatibility and thermal requirements, using modern techniques and tools (WA1, WA2, WA3, WA4, WA5, WA12)

  • LO3: Learn how to model power electronic systems and three phase motors for control design, including state space based and vector control. (WA1, WA2, WA5)

  • LO4: Design and build a modern high-power dc/dc converter control system in a team environment. (WA1, WA2, WA3, WA4, WA5, WA9, WA10)
    • University Graduate Attributes

      This course will provide students with an opportunity to develop the Graduate Attributes specified below:
