摘　　要：采用多重化方案实现的大容量有源电力滤波器(Active power filter,APF)具有等效开关频率高等优点,但传统的多重化方案公用一组直流侧电容,容易出现多次相交或静态补偿误差较大等问题。文章提出了一种新的多重化方案,将各模块的直流侧解耦,避免了采用传统的多重化方案时存在的问题,同时具有提高等效开关频率、降低纹波电流的优点。仿真结果验证了推导的正确性,实验结果表明具有新的多重化结构的有源电力滤波器有良好的补偿性能。Large capacity active power filter (APF) with main circuit of multiple configuration has the merit of high equivalent switching frequency. But each module of the APF with traditional multiple configuration shares one DC link capacitor, it tends to cause problems such as intersection many times in one carrier's cycle or higher static compensation error. In order to solve these problems, a new multiple configuration is presented in this paper. The DC link bus of each module is separate in order to achieve the decoupling of each module. It also remains the virtue of higher equivalent switching frequency and lower current ripple. Simulation results prove the validity of the deduced conclusions and experiment results show that the APF with the new multiple configuration has good performance.
