A Novel Topology of Resonant Reset Two-Transistor Forward Power Converter

This document proposes a novel two-transistor forward DC/DC converter with resonance reset. It is recommended because the duty circle is able to exceed 50% and the efficiency of the converter is higher which is superior to the conventional. The principle of operation of the enhanced configuration is illustrated and some simulation is employed to prove its practicability and superiority. Finally a 80V~140V input, 12V/8.3A output DC/DC converter prototype is founded for verification.
