新能源汽车零部件电磁兼容测试及案例分析

New Energy Vehicle Parts Electromagnetic Compatibility Test and Case Analysis

新能源汽车中由于应用了高压和大电流的大功率电子变换装置和驱动电机,会产生严重的电磁干扰噪声。因此电动汽车的电磁兼容性问题比传统燃油汽车更为复杂和严重。本文以新能源车电机控制系统为案例,对新能源汽车零部件电磁兼容测试进行研究。

High power electronic converter and drive motor with high voltage and high current are used in new energy vehicles,which will produce serious electromagnetic interference noise.Therefore,the EMC problems of electric vehicles are more complex and serious than that of traditional fuel vehicles.This paper takes the motor control system of new energy vehicle as an example to study the EMC test of new energy vehicle parts.
