Summary: 
This paper deals with a simple and practical power loss analysis simulator, which can actually estimate the total power losses of three phase voltage-fed Auxiliary resonant commutation pole snubber assisted soft switching inverter as well as hard-switching inverter. In order to estimate the switching power losses and conduction power losses of switching semiconductor power devices (IGBTs), which are incorporated into the inverters, the proposed practical simulator is making use of feasible switching power loss data tables and conduction power loss data tables, which are accumulated from the measured voltage and current operating waveforms of power semiconductor switching devices. The practical effectiveness of feasible simulation technique and power loss evaluations for power electronic conversion circuits and systems are confirmed by the simulation and experimental results basis under the conditions of soft switching and hard switching sinusoidal PWM schemes.
