This paper studies the performance of a three phase Hard Switching Inverter (HSI) for low power applications, operating primarily at partial load (7W, 150 mA-peak, 50 V-peak which is 10%of its thermally maximum permissible power) in a home appliance application. Analytic methods are used to calculate the losses for different power transistors, resulting in an optimized H-Bridge Inverter (HBI) prototype. The standard hard-switching approach is used, the potential of gate loss reduction by using a Resonant Gate Drive Circuit (RGD) is investigated.
