Abstract
-The introduced PWM-switch modeling method is a simple method for modeling pulse-width-modulated (PWM) dc-dc converters operating in the continuous conduction mode. The main advantage of this method is its versatility and simple implementation compared to other methods. The basic idea is the replacement of the switches in the converter by their time- averaged models. These switch models have been developed in such a way that the converter model provides the same results as the state-space-averaging technique but now including nonlinear effects. Simple rules for determination of the switch models are obtained. The resulting model is a time-averaged equivalent circuit model where all branch currents and node voltages correspond to their averaged values of the corresponding original currents and voltages. The model also includes parasitics, second-order effects and nonlinearities, and can be implemented in any circuit-oriented simulation tool. The same model is , for the simulation of the steady-state and the transient behavior. Buck- boostKeywords
