Modeling of switching and conduction losses in three-phase SPWM VSC using switching function concept

The designer of power converters must model the losses of converter switches to optimize the performance of system. In this paper, the losses of three-phase SPWM VSC are modeled using switching function concept. This model is simulated and its results are compared with accurate method, which is based on the semiconductor characteristics. It is shown that the suggested method includes simplicity, convergence, and short run-time of simulation.
