Auxiliary quasi-resonant commutation block snubber assisted voltage source three phase soft switching PFC rectifier

摘要

This paper presents a new active resonant snubber assisted (Auxiliary Quasi-Resonant Commutation Block-Link; ARCB) voltage source three phase soft switching PWM-PFC rectifier, which can operate under a principle of Zero Voltage Soft Switching (ZVS) commutation. The operating principle and the performances of this digitally-controlled three phase voltage source soft switching PWM-PFC rectifier are illustrated and evaluated on the basis of computer aided simulation analysis.
