摘　　要：文章重点研究动车组脉冲整流器,对其采用预测直接电流控制法进行控制,创造性地采用陷波滤波器法来降低直流侧电压低次谐波,采用比例谐波控制器来降低直流侧电流低次谐波。根据控制原理,运用Matlab建立仿真模型。仿真结果与实际情况相符,该研究工作为动车组脉冲整流器的谐波抑制研究提供了理论参考。This article focuses on the pulse rectifier of EMUs, and controls the pulse rectifier with method of predicting direct current control. Creative method of notch filter is used to reduce the low harmonics voltage in DC side. Harmonic proportion controller is used to reduce the low harmonic current in DC side. According to the principle of control, simulation model is established by Matlab in this article. The simulation results are in conformity with actual situation. The research work provides a theoretical reference for the pulse harmonic suppression of the rectifier of EMUs.
