Comprehensive power loss model of the main switch of the Flyback converter

Abstract

This paper advocates a comprehensive loss modeling of the DC-DC high switching frequency Flyback converter by taking into consideration of switching loss, conduction losses and gate charge losses of the main switch of the converter. For this aspect, it envisages a significant loss mechanism along with switching parameter. Effective Loss computation plays an important role to determine the performance of the converter to demonstrate with simple empirical equations. Finally, major losses along with the gate charge of the Flyback converter are included with simple explanations to boost up the overall performances and loss modeling of Flyback circuit. Due to above huge losses, the Flyback converter is used for low power industrial applications.
