一种用于高输入电压低功率应用的输入串联辅助电源方案的研究与实现

Aiming at the high-input-voltage multiple-output low-power applications, an input-series two-transistor flyback auxiliary power supply scheme is proposed and investigated. In this converter, an integrated-transformer is adopted instead of the single-transformer in each series-module, all of the series-modules are operating synchronously, and the input voltage sharing (IVS) can be achieved automati...
