Power Electronics Design for Electromagnetic Compatibility

This 1-day course covers fundamental and advanced design concepts related to the design of power electronic circuits for meeting electromagnetic compatibility requirements. In the morning session, basic power electronic circuit topologies and applications are reviewed with a focus on the fundamental properties of these circuits that result in unwanted conducted and radiated emissions. Noise source models are presented and various noise mitigation options are examined. The focus of the afternoon session is on advanced design concepts including grounding strategies, component selection and placement, and methods for maintaining electrical balance. Active noise cancellation techniques applicable in various situations are also presented. Finally, examples of good and bad power circuit designs ranging from low-voltage DC-to-DC converters to 700-volt electric vehicle motor drives are reviewed.
