摘　　要：该文提出单周控制有源滤波器(UCI-APF)的双向互补控制方案。该方案通过双路控制方式来提高系统稳定性。与以往单周控制相比较,双向互补控制能有效扩大滤波器的稳定工作范围,消除进线电流直流分量与低频次谐波,从而解决了单周控制有源滤波器在实际场合应用的关键性问题。分析与实验结果验证了新方案的可行性。This paper presents a novel double-direction compensation control scheme for UCI-APF. In order to improve the stability of UCI control, double loop control is used. In contrast to previously proposed control method used for UCI-APF, the new one can effectively enlarge the stable region. Meanwhile, the dc offset and the sub-harmonic in line-current can also be suppressed. Therefore, the key problems of UCI-APF are solved. Experimental results show that the strategy can be feasible for practical application.
