Diode Rectifier Circuits with Commutation Capacitors for Three-Phase Rectangular-Waveform Distribution System

摘要

This paper presents diode rectifier circuits with commutation capacitors in the three-phase rectangular-waveform distribution system. The commutation capacitors can improve the input total power factor and realize the zero voltage switching of the diodes. From the analysis, the authors also propose the design method of the rectifier circuit. In order to verify the effectiveness of the proposed method, the experimental characteristics of the rectifier circuit have been shown.
