摘　　要：将三相有源电力滤波器的电流波形控制转化为3个单相有源电力滤波器的波形控制,从而可采用成熟的重复控制和状态反馈控制方法,介绍了三相变单相的转化方法,以及利用状态反馈环节改善系统的稳定性,重复控制策略改进了输出电流波形校正精度的控制思路,并通过仿真验证了该方法的有效性。In this paper, the transfer method from three-phase into single phase is introduced by way of transferring waveform control from three-phase APF into to that of three single-phase so to use mature repetitive and state feedback control strategy. The system stability is improved by the use of the feedback control strategy. The control idea of correction accuracy of output current waveform is improved by the repetitive control strategy and the effectiveness of the method is verified by the simulation.
