The main electromagnetic interference risk of new energy vehicles comes from the switching behavior of high-voltage devices in the electric drive system.According to GB/T 18655-2018,GB/T 36282-2018 and related enterprise standards,the electromagnetic compatibility performance of the electric drive system must be strictly controlled within the specified range.In response to this problem,a new-energy vehicle electric drive system electromagnetic compatibility closed-loop development technology under load conditions is proposed,which mainly includes three key links:test platform development,test equipment development and simulation platform development.This article focuses on the research on the on-load test equipment and simulation platform of the electric drive system,and develops a set of through-wall electric drive system on-load test equipment that meet the standard requirements.Based on an integrated electric drive system,an electric drive system on-load simulation platform was established,the accuracy of the model was verified through simulation and testing.The parameters were analyzed and the electromagnetic interference performance was optimized.Finally,a closed-loop electromagnetic compatibility performance control system is formed.
