Abstract: This paper introduces the EMC test standard of the motor drive system for electric vehicles, and recommends the standard that parts manufacturers can refer to first. The main interference sources and propagation paths of the motor drive system are analyzed, and the design points for EMC problems in the system design are put forward according to the analysis, and the validity of the design is verified by the ground test of the actual prototype system.

Key words: Motor drive system, EMC test standard, EMC design essentials
