Two interleaving methods for two-transistor forward converter

Abstract

Two interleaving methods for two-transistor-forward-converter are presented in this paper. The operation stages are analyzed briefly. The static and dynamic performance are analyzed and compared. In static analysis, the ripple currents of filter inductors and output capacitors in both methods are discussed and compared, and the current and voltage stresses of devices are investigated and compared. In dynamic analysis, small signal models for both circuit are built, which are analyzed and compared in CCM and DCM respectively. Finally, simulation and experiments are performed to verify the analysis and comparison.
