چکیده
Abstract – Power factor corrected rectifiers are new tendency in development of power supplies. This paper presents a brief review of some high power rectifiers structures and provides an assessment of each analyzed technology. As contribution, a novel hybrid high power rectifier topology is proposed and analyzed. An active unidirectional three phase rectifier is associated in parallel with a three-phase 6-pulse diode bridge. The main objective is to achieve a unity power factor high power converter, so that 50% of the total power are processed by the diode bridge and the other ones 50% for the active rectifier. The mathematical analysis and simulation results for a 26kW converter are presented.

متن کاملDesign and Simulation of a New DC Power Supply Based on Dual Bridge Matrix Converter
A conventional high power DC power supply systems consist of a three-phase diode rectifier followed by a high frequency converter to supply loads at regulated DC voltage. These rectifiers draw significant harmonic currents from the utility, resulting in poor input power factor. In this paper, a DC power supply based on dual-bridge matrix converter (DBMC) with reduced number of switches is p...
