3-Level Three Phase Soft-Switching PWM Rectifier with Single Auxiliary Resonant Commutated Snubber Circuit

Abstract

This paper presents a novel type of 3-level 3-phase 3-switch type voltage-fed soft-switching PWM AC/DC Converter with new Active Auxiliary Resonant Commutated Snubber topology which can operate under a condition of Zero Voltage Switching. The operating performances of the proposed three phase soft-switching PWM rectifier which is more suitable for power systems applications is evaluated on the basis of Simulation results.
