Abstract
The accurate simulation of power electronic systems is possible when including the semiconductor devices, but practically not affordable. Classical ideal averaged models of the system are not suitable either. Hence, averaged models including the non-ideal effects of the power semiconductor devices appear quite efficient. In this paper, a non ideal averaged model of the PWM-Switch operating in continuous and discontinuous conduction modes is developed The main advantages of the proposed averaged model are the takes into account of the nonlinear effects of power devices and the influence of the stray inductance in the DC loop, on the switching characteristics. The model is useful in determining the device's switching and conduction losses and its junction temperature.
