摘　　要：文中首先建立了单台APF小信号等效模型,从PCC处将单台APF等效模型拓展到多台并联模型,通过对谐振电流特性的分析,我们得出了两台APF并联具有与N台APF并联相似的谐振电流特性,分析了APF补偿电流突变和并联台数对并联系统谐振特性的影响。最后,通过实验研究,验证多台APF并联系统小信号等效模型和谐振特性分析的正确性。Firstly, a small-signal equivalent circuit model of single APF is established, and is expanded into a small- signal model for multi-paralleled APFs. Through the analysis of the characteristics of the resonance current, we conclude that two paralleled APFs have similar resonant current characteristics with TV paralleled APFs. And then,on this basis, the basic resonance characteristics of multi-paralleled APFs are analyzed when the load current and parallel number change. Finally, the correctness of the proposed equivalent model and analysis of resonance characteristics is verified by experiments.
