| Abstract: | The power dissipation model of synchronous rectification flyback converters was established. The various power dissipation factors in operating process of power MOSFET of synchronous rectification for main switch ing device and switched power MOSFET were analyzed in detail. At the same time,the power dissipation model and related affecting factors of transformer,filter capacitor and other main components were analyzed theoretically. Using MathCAD software,the concrete sample analysis of power dissipation for synchronous rectification flyback converter was carried out,and the validity of power dissipation model analysis was verified by experiments. |
