Abstract
Contrary to the classical ideal averaged models, the introduced averaged model includes the nonlinear effects of the power semiconductor devices. The proposed nonideal pulse width modulated (PWM)-switch model is a useful method for modeling pulse width modulated converters operating in the continuous conduction mode. The main advantages of the proposed averaged model are that it takes into account the nonlinear effects of power devices and make it possible to estimate the dissipated power in the different circuit devices. The proposed model can be applied to bi-directional converters and allows the electrothermal simulations of the power electronic system. A simple technique to evaluate the different static and dynamic parameters of the devices, from manufacturers data sheets or experimentally, is presented.
