Abstract

A variety of soft-switching techniques have been proposed to reduce the switching losses and EMI problems that occur with higher switching frequencies in hard-switched power converters. In this paper, a new, quasi-resonant, soft-switched, three phase inverter is presented which uses 12 thyristors as the power electronic switches, and hence has potential for use in high power applications. The power converter is fully current regulated, suitable for high performance motor drive applications, and is capable of four-quadrant operation to allow regeneration back into the DC supply. The operation and the control of the inverter are described in detail and simulation and experimental results are presented
