一种基于变压器集成的高输入电压辅助电源输入串联反激方案

An input-series flyback auxiliary power supply scheme is proposed and investigated, which is suitable for the high-input-voltage multiple-output low-power applications. In this power supply, a common integrated-transformer is adopted, all of the series-modules are operating synchronously, and the active input voltage sharing (IVS) can be achieved efficiently without any special controller. The act...
