摘要：
A generalization of the model of PWM switch according to Dijk et al. for averaged modeling of switched DC-DC converters is proposed This model now includes the on-resistance of the active switch, and the forward voltage drop and the differential resistance of diode-type passive switch. The way this model is compiled allows for the influence of parasitic ESRs of the capacitors in the circuit such that the resulting equations are equivalent to the averaged state space equations. The procedure of PSPICE modeling and the results of computer simulation of boost converter are shown.
