| Abstract |
In this paper, described is a practical design procedure for prototype of the auxiliary resonant
commutated snubber circuit (ARCS) incorporating a current feedback transformer with power
regeneration loop. For realization of three phase voltage-fed soft-switching inverter, soft-switching
active power filter and reactive power compensator, This type of soft-switching power conversion
topology has significant merit of effective and peak current rating reduction for auxiliary active
switching devices in the ARCS. This paper also presents a novel version of digitally-controlled
voltage source type space vector-modulated inverter with ARCS which can operate under a zero
voltage soft-switching condition. The steady-state operating analysis of this ARCS has the remarkable
features and the practical design procedure of this resonant snubber are illustrated on the basis of
computer simulation analysis. The steady-state operating performance of this soft-switching inverter
with ARCS are evaluated and discussed as compared with conventional three phase voltage source
space vector modulated inverter operating at hard switching-transition mode. |
