A New Standby Structure Using Multi-Output Full-Bridge Converter Integrating Flyback Converter

Abstract

This paper presents a new standby structure where the standby flyback converter is integrated with the zero-voltage-switching multi-output full-bridge dc-dc converter. While the standby power is generated from the conventional flyback converter in standby mode, the auxiliary output of the multi-output full-bridge converter is used for the standby output in normal mode. The validity of this proposed structure is confirmed by the experimental results from 12 V/58 A for the dc-dc output and 5 V/3.2 A for the standby output prototype.
