Abstract:

This paper presents a generalized dynamic model for flyback switching AC-DC converters. Comparing with the current model in the published literatures, several important factors are taken into account, including the anomalous loss in magnetic cores, differential inductance and leakage inductance. In order to obtain accurate parameters, nonlinear finite element analysis method is used to calculate some key parameters of transformer: differential inductance and leakage inductance. Furthermore, a modified flyback transformer model is built. The systematic method to build the hybrid model-system switching state based on time sequence is also introduced. A simulation model in MATLAB/Simulink, in which all three operational modes are included, is built. The developed model is validated by executing the model on an existing converter, and several performances are obtained.
