Abstract

Based on the mechanism that the primary and secondary currents of flyback converter do not appear at the same time, two different equivalent models of flyback transformer are brought forward correspondingly. Stage by stage analysis of the working process of both continuous conduction mode(CCM) and discontinuous conduction mode(DCM) is presented by using appropriate transformer equivalent model in different stages. The presented transformer equivalent models can be used for theoretical calculation as well as PSpice simulation. Simulation results of a real converter are given in the analysis. Experimental waveforms are compared with the analysis to show the correctness of the modeling and analysis.
