Feasible evaluations of space vector modulated three-phase soft-switching PFC rectifier with instantaneous power feedback scheme

This paper presents a performance analysis of active auxiliary resonant commutation bridge-leg snubber-assisted three-phase voltage-fed soft-switching PFC rectifier using IGBTs which can operate under a condition of zero voltage switching (ZVS) using a digital control scheme based instantaneous power feedback. This power converter is suitable for high power applications as compared with the other types of snubber assisted soft switching power conversion system. The operating performances of this three-phase PFC rectifier are illustrated and evaluated on the basis of simulational and experimental results.
