Publication Abstract

In this paper, a one‐cycle‐average (OCA) discrete‐time model for PWM dc‐dc converter based on closed‐loop control method for discontinuous conduction mode (DCM) is presented. It leads to exact discrete‐time mathematical representation of the average values of the output signal. It also provides the exact discrete‐time mathematical representation of the average values of other internal signals with little increase in simulation time. This model is designed without any approximation unlike the existing models. A comparison of this model to other existing models is presented through a numerical example of boost converter. Numerical simulations results confirm the accuracy and speed of the proposed model.
