Research on Deadbeat Control in the Active Power Filter

Zhu Jun-xing

Abstract

A compound harmonic current detection of the active power filter(APF),including the load current detection and the source current detection is proposed.A novel deadbeat control strategy is proposed for the APF with four-bridge topology.Based on the analysis of the topology of the system,a complete mathematical model is established.The coupling a-mong the output harmonic currents of every phase in the APF is analyzed,and the decoupling method is presented.The simulation and experimental results demonstrate the effectiveness of the proposed compound harmonic current detection method and the deadbeat control strategy.
