Full-Order Nonlinear Model and Analysis of Flyback Converters in DCM

Abstract:

A new modeling method for flyback converters in DCM is proposed in this article. On the basis of the method of state-space averaging, using the new duty ratio constraint and the modification matrix M, the modified averaged model is derived here, then the nonlinear full-order model is established. Finally, the transient response and control-output transfer function of the proposed model are simulated in Saber, the results show that the new modified average model is accurate enough.
