Abstract

This paper extends the results of discrete-time averaging method presented before to include the effect of feedback loop in the PWM system. This model provides the exact one cycle average values of the output signal with the presence of feedback even at low switching frequency. A comparison of this model to other existing models is presented through a numerical example of boost converter. Simulation results confirm the better accuracy and speed of the proposed model
