A new standby structure using multi-output full-bridge converter integrating flyback converter

摘要

This paper presents a new standby structure where the standby flyback converter is integrated with the zero-voltage switching (ZVS) 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 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 12V/58A for DC-DC output and 5V/3.2A for standby output prototype.
