Design and study on output filter of parallel active power filters

Hua Zhang

Abstract

Although the output filter(OF) influences the compensating ability of active power filters(APF),few study focused on it.The paper presents a parameter design and optimization method of OF based on the analysis on its structure and principle.The simulation and experiment result of non-linear load compensation performances has verified that the proposed design method is feasible.OF selected by this method can eliminate effectively high frequency harmonics and enhance the efficiency of APF.
