Abstract

Partial load operation efficiency of motor drives has attracted increased attention for various applications. The charging and discharging of the parasitic winding capacitances significantly contribute to the inverter switching losses and thus to the losses at partial load. This paper studies the reduction of these losses by use of Auxiliary Resonant Commutated Pole (ARCP) as a soft switching half bridge topology, based on high performance GaN devices. The switching losses of soft and hard switching half bridges are compared experimentally. For hard switching, theoretical results in line with experimental ones are shown, as well. The experimental results show that the switching losses caused by the parasitic winding capacitance can be decreased to 10 %.
