摘　　要：为提高三相有源电力滤波器(APF)在某些特定场合补偿正、负序谐波电流的能力,首先对常见的三相整流器进行了相序分析,得到了此类非线性负载交流侧电流的相序信息;然后利用多同步旋转坐标变换,将各次正、负序负载谐波电流变成直流指令,通过经典的比例-积分(PI)加重复的电流跟踪复合控制策略,实现了各次正、负序负载谐波电流的无静差补偿;最后给出了仿真与实验波形,分析了三相APF正、负序谐波补偿性能,验证了分序控制策略的有效性。To improve the ability of three-phase shunt active power filter（APF） compensating positive and negative sequence harmonic current in some specific applications,the phase sequence information of each harmonic current is get by theoretical analysis of three-phase rectifier load.Then using the strategy of multiple synchronous rotating coordinates transformation,each positive or negative sequence harmonics should be transformed to DC component,which are controlled by proportion-integral（PI） plus repetitive control combined regulators in order to implement zero steady-state error compensation.Finally,simulation and experimental verification proves that the APF can effectively compensate the positive and negative sequence harmonic current according to this strategy.
