Abstract: In view of the electromagnetic compatibility (EMC) problems existing in electric vehicle switching power supplies, this paper introduces the EMC characteristics of switching power supplies, expounds the electromagnetic interference (EMI) problems and interference mechanisms of switching power supplies, reviews the EMC predictive analysis methods of switching power supplies, and summarizes the EMI suppression technologies of switching power supplies. It is pointed out that establishing precise EMC simulation analysis models, conducting EMC scheme design and system optimization, and studying practical EMI suppression technologies for switching power supplies are urgent problems that need to be solved. This research on the EMC of electric vehicle switching power supplies has certain reference value.
