The circuit topology of the proposed converter is composed of a boost converter and a flyback converter with cascode connection. Leakage inductance and magnetizing inductance are required to charge and discharge the parasitic capacitance of the switch in order to achieve the main switch and auxiliary switch operated at the zero voltage switch. Meanwhile, the auxiliary switch can synchronize rectification and reduce conduction losses. The operating principle and design process of the zero voltage switching for Boost-flyback converter are presented in this thesis. Finally this study developed a prototype cascaded flyback DC/DC converter with an input voltage of 48 V, output voltage of 400 V, and output power of 100 W. The experimental results verified the performance of the proposed cascaded converter. Ching-Lung Chu 朱慶隆 學位論文 ; thesis 73 zh-TW |
