摘　　要：电流跟踪控制环节是影响有源滤波器补偿效果的重要环节,为保证有源电力滤波器具有良好的补偿电流跟随性能,必须将变流器直流侧电压控制为一个适当的值。实际系统中直流侧电源一般用电容代替,因此针对单周控制,加入PI调节器控制直流侧电容电压,通过仿真分析,验证了该方案的有效性。Current tracking control plays a key step in ettacting active power filter＇s compensation effect. To guarantee good tracking property of Compensating current of active power filter, DC voltage of convertor must be controlled as a appropriate value. In actual system, DC power usually is replaced by capacitor. So the PI regulator was added to one-cycle control to control DC voltage. The results prove the validity of this program through simulation.
