• In this paper, an analysis of switching and conduction losses in hysteresis current-controlled inverters is presented. The switching frequency variation which is important in switching loss evaluation is first analyzed considering the voltage drop across the load impedance in series with the load counter emf. Based on this analysis, the expression for the switching losses is derived. As for the conduction losses, a concept of probabilities of the transistors receiving ON and OFF signals is introduced to calculate them since the switching instants of the power devices can not be predetermined. Experimental results are included to verify the proposed method.
