摘　　要：在混合有源电力滤波器中,采用电流源控制方式可比电压源控制方式获得更好的滤波性能,但由于采用常规电流源控制方式不能迫使无源滤波器部分承担电网基波电压,因而不能有效降低混合有源滤波器中有源部分的容量。研究一种通过在指令电流中加入适当基波分量,迫使混合有源滤波器中的无源滤波器部分承担电网基波电压的方法,将电流源控制策略应用于并联混合有源电力滤波器。研究结果显示,这种方法可以有效改善混合有源电力滤波器的性能。Better filtering effect, dynamic character and stability may be achieved by current source control strategy in Parallel Hybrid Active Power Filter （PHAPF） . However, general current source control strategy can trot make the passive filter part of PHAPF bear the fundamental voltage of power line, so that the output power of the active part of PHAPF is not reduced,and the advantages of HAFt＂ can not be achieved. A new method, in which proper fundamental is added to the instruction current so that the passive filter part is forced to bear the fundamental voltage, is proposed. By the new method, current source control strategy can be used in PHAPF, and the performance of PHAPF is improved.
