Research on a Novel Interleaved Flyback DC/DC Converter

Flyback converter has been widely used in low-power applications because of its relative simplicity when compared with other topologies. This paper proposes a novel interleaved flyback DC/DC converter, which provides the additional benefit of recycling transformer leakage inductance energy and reducing voltage stress of the power switches. Its input and output current ripple is much smaller than basic flyback converter. The operation principle and design considerations are analyzed and verified by the simulation and experimental results
