摘　　要：为抑制电机驱动系统传导干扰发射,提出一种基于转移函数的共模EMI滤波器设计方法。采用该方法针对一个电机驱动系统设计了逆变器直流侧和交流侧共模电磁干扰滤波器。实验结果表明,该方法能够在保证交流侧共模干扰强度不增加的同时,有效抑制直流侧共模干扰。In this paper, the filter design method for motor drive systems is studied. First, the target transfer function is selected based on the limit values of the conducted interference in electromagnetic compatibility（ EMC） standards. Then,the parameters of the filter components are determined using nonlinear least squares method,and the filter topology is selected subsequently. The proposed method is utilized to design the common mode filters for both DC and AC side of a motor drive system. The experiment results show that the DC side common mode interference can be effectively mitigated,while not increasing the AC side common mode noise.
