| 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 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 converter is fully current-regulated, suitable for high-performance motor drive applications, and is capable of 4-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 |
