Simulation of ARCP converter with physics-based circuit simulator device models

Abstract

Former simulation studies of the auxiliary resonant commutated pole (ARCP), a well-known high power soft-switching inverter, have invariably used simplified power device models, obtaining fast simulation speed, but sacrificing accuracy. In this research, we apply to the simulation of the ARCP converter physics-based IGBT and power diode models, which have been proven robust in the hard switching circuit simulation. With this approach, it is possible to obtain more detailed waveforms of the commutation process and more accurate estimation of the system losses.
