Abstract :
In this paper, a high frequency transformer-assisted auxiliary active resonant commutated snubber (HFTA-ARCS) for voltage source power conversion is presented. A three phase voltage source type soft switching inverter incorporating HFTA-ARCS circuits in its three bridge legs can reduce current rating of auxiliary active power switches and simplified sensorless control scheme without specified boost current management required for soft switching. Its operating principle and digital control scheme are described and a practical design procedure of circuit parameters on this HFTA-ARCS circuit is also introduced on the basis of computer simulation results. The effectiveness of this inverter is proved on the basis of performance evaluations and is also compared with the conventional three-phase hard switching inverter under the conditions of specified parameters
