Abstract

In this paper, a prototype of the auxiliary resonant commutated snubber circuit (ARCS) incorporating a pulse-current feedback high-frequency transformer with power regeneration loop is described for three-phase inverter from a practical point of view. For three-phase voltage-fed soft-switching inverter, soft-switching active power filter and active PFC rectifier, the soft-switching inverter topology treated here has significant advantages of effective power loss reduction in the auxiliary active switching power devices in the ARCS. In addition, this paper presents a DSP-based digitally-control space vector-modulated three-phase voltage-fed inverter with high-frequency pulse-current transformer (HFPT) assisted ARCS, which can efficiently operate under a stable condition of a zero voltage soft-switching commutation. The steady-state operating circuit analysis of the new ARCS has the salient features and the practical design procedure of this resonant snubber are illustrated and discussed on the basis of simulation and experimental results. The operating performance of this soft-switching inverter using IGBT power modules and its evaluations in the steady-state are actually discussed as compared with the conventional three-phase voltage-fed space vector modulated hard-switching inverter.
