Abstract
Operation in critical conduction mode of flyback converters has many advantages over constant frequency PWM. In this paper, this operation is briefly examined and a precise large signal model for the converter is proposed and verified. The model shows an almost linear behavior in a large range of feedback voltage. Therefore a classical Laplace analysis can be performed. There is an excellent agreement among the results obtained from large signal SIMULINK simulation, Pspice simulation and experiment.
