Implementation of High Efficiency Soft-switching Flyback Converter

Recently, power supplies with low voltage/high current output are widely used, but conventional power supplies have large power loss, and thus the system efficiency is low. However their control technique is complicated and their elements are many. In this paper, Implementation of High Efficiency Soft-switching Flyback Converter is presented. The proposed converter has been implemented to verify the proposed topology with 5V/20A prototype and theoretical operation under various load condition and universal input voltage range.
