摘　　要：通过Matlab中Simulink模块搭建的系统仿真模型,通过仿真研究了直流电源中谐波对滞环电流控制性能的影响。其中滞环电流控制电路中的直流电源是通过三相整流电路得到,而直流电源的谐波的变化通过改变与整流电路输出并联的电容容值实现。仿真表明,谐波使得逆变输出波形畸变,严重时甚至会造成滞环电流控制跟踪失败。A simulation model is built based on the Simulink module in the Matlab to study the effect of DC power harmonics on hys-teresis current control performance. The DC power supply in the hysteresis current control circuit is supplied by a three-phase rectifier circuit, and the harmonics of DC power supply vary with the capacity value of the capacitor which is in paral el to the rectifier circuit output. The result of experiment shows that the harmonics cause the inverter output waveform distortion, even cause the hysteresis current control tracking failure.
