摘　　要：某纯电动汽车电机控制器在工作时产生过大的无功功率和纹波电流,形成传导性电磁干扰,进而导致电动空调控制器烧毁。本文在理论分析和试验测试的基础上,采用增大电机控制器输入端滤波电容容量的方法,补偿电机控制器产生的无功功率,抑制纹波电流的产生,消除传导性电磁干扰。试验验证的结果表明,故障得到圆满解决。The motor controller in a battery electric vehicle generates too large reactive power and ripple current in operation, producing conducted EMI and hence resulting in electric air conditioner burned down. Based on theoretical analysis and test, this paper adopts a scheme of increasing the capacitance of input filter capacitor in motor controller to compensate reactive power, suppress the generation of ripple current, and hence eliminate conducted EMI. The results of test verification indicate that the fault is successfully resolved.
