Abstract

In this paper, a high frequency pulse current transformer-assisted auxiliary active resonant commutation snubber (HFTA-ARCS) for voltage source power conversion is proposed. 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 method of circuit parameters on this HGTA-ARCS circuit is also introduced on the basis of computer simulation results. Moreover, this space vector modulated soft switching inverter system with DSP-based digital control scheme is discussed on the basis of performance evaluations. The effectiveness of this inverter is proved by the simulation results and this inverter system is also compared with the conventional three-phase hard switching inverter under the conditions of specified parameters.
