Abstract

A novel full-bridge converter with a new energy-recovery driver implemented a regenerative transformer is proposed to improve the efficiency for wide input voltage range and load variation. The main switches achieve ZVS independent of the load current condition. During the free wheeling period, conduction loss is minimized by recovering the circulating energy to the source. The principle of operation, design consideration and experimental result, including efficiency, are presented in the case of large variation of the input voltage or load. A proposed 1kW converter prototype is compared with a PS-FB converter.
