A New Zero-Voltage Switching Half-Bridge Converter With Reduced Primary Conduction and Snubber Losses in Wide-Input-Voltage Applications

In this paper, a half-bridge (HB) converter, additionally employing a diode compared with the conventional modified duty-cycle-shifted (MDCS) HB converter, is proposed to achieve a high efficiency in wide-input-voltage and low-output-current applications. Since the proposed converter has symmetrical...
