Modeling and Resonance Analysis of Modular Shunt APF
Firstly, a small-signal 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 has similar resonant current characteristics with N 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 proposed equivalent model and analysis of resonance characteristics are verified by experiments.
