Mythbusting EMC Techniques in Power Converters

Proven Ways to Improve EMC in Your Power Converter Design

The growing popularity of electric vehicles (EVs) is driving an increase in the concentration of electronic circuits in modern vehicles, placing significant pressure on designers and manufacturers to meet strict electromagnetic compatibility (EMC) standards. This session presents the results of a series of tests that have been carried out in a certified EMC laboratory to objectively determine the effect of different engineering practices that are intended to optimize EMC in power converters, focusing on four key aspects of EMC-compliant power converter design:

  1. Hot-look size and cancellation
  2. Input filter position
  3. Cuts in the ground plane
  4. Inductor shielding
