Throughout the 2021-22 academic year, we will be prioritising face to face teaching as part of a blended learning approach that builds on the lessons learned over the course of the Coronavirus pandemic. Teaching will vary between online and on-campus delivery through the year, and you should read guidance from the academic department for details of how this will work for a particular module. You can find out more about the University’s overall response to Coronavirus at: https://warwick.ac.uk/coronavirus.

Introductory description

Practically all electronic equipment, whether domestic or industrial, requires power conditioning to deliver the energy for it to operate correctly. This is using electronics for power processing, not information processing. The applications vary widely from power supplies for laptops and mobile phone chargers, through industrial motor drives, hybrid and electric vehicle drives, electric rail transport, to solar and wind energy systems and power transmission and distribution systems.

Module aims

The module aims are:

  • To introduce the concept of power electronics as power processing and control, and to present the range of applications of power electronics in today’s society.
  • To introduce power semiconductor devices as basic switching elements used in power electronic converters, and describe the theory of their operation.
  • To introduce power electronic converters, explain their operation and give examples of applications.
  • To develop an understanding of the issues present in converter and device design, including the impact of physical layout and heat dissipation.
Outline syllabus
