Averaged Model for PWM DC-DC Converters Operating in DCM Considering Conduction Losses
Al-Numay, Mohammed S. . 2012
This paper presents a one-cycle-average (OCA) discretetime model for PWM dc-dc converters operating in constant frequency discontinuous conduction mode (DCM). This model provides the exact OCA values considering non-ideality in the switching stage components. It leads to exact discrete-time mathematical representation of the average values of the output signal. This model 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 other 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.
