Analysis and Design of Diode Rectifier Circuits with Commutation Capacitors for Three-Phase Rectangular-Waveform Distribution System

Abstract

This paper presents an analysis of steady and transient characteristics of the diode rectifier circuits with commutation capacitors for the three-phase rectangular-waveform distribution system. The commutation capacitors can improve the input total power factor, and reduce the ripple of the output voltage. From the analysis of the diode rectifier circuit, the authors also propose the design method of the input inductances, the commutation capacitors and the output smoothing capacitor. In order to verify the effectiveness of the proposed method, the experimental characteristics of the rectifier circuit have been shown.
