摘要：

Aiming at the high-voltage low-power applications, an output-series flyback converter is presented and analyzed in this paper. In this converter, the series output circuits enjoy a common power transformer and a common power switching circuit in primary side of the transformer, and the active output voltage sharing (OVS) of each output circuit can be achieved due to coupling of the transformer secondary windings. Operational principle of this output-series converter is presented in detail, and the active OVS mechanism is analyzed, based on which a 800V laboratory-made prototype of this output-series flyback converter is built, and the theoretical analysis is verified by the experimental results.
