摘　　要：由于电动汽车的车内存在大功率、大电流的驱动系统,电磁干扰特性同传统车辆相比有很大不同。大功率的电力电子装置在运行过程中会产生很强的电磁干扰,可能会使整车运行不稳定或影响车载或车外附近电气设备的正常工作。目前还没有专门针对像电动汽车驱动系统这样大功率、大电流零部件的电磁兼容标准,传统的电磁兼容检测方法和试验布置也不再适用。介绍了国内外在电动汽车驱动系统电磁兼容性方面的研究成果及其发展趋势。The electromagnetic interference（EMI） characteristics of the electric vehicles are different from that of conventional vehicles materially owing to the existence of the high-power,high-current electric drive system.The high-power electronic devices will produce strong EMI during their operations,which may make the vehicle run unstable or influence the normal work of the electrical equipment in the vehicle or outside.Currently,few electromagnetic compatibility（EMC） standards have been drafted specifically for the components like high-power,high-current electric drive systems in the electric vehicles.Meantime traditional EMC test methods and test arrangements are no longer applicable.This paper introduces the research achievements and trends in this respect.
