Abstract :
This paper proposes an interleaved flyback converter with a novel L-C-D snubber to reduce turn-on and turn-off losses. The proposed L-C-D snubber is composed of a single capacitor to form turn-off snubber, and an inductor and a diode connected in parallel to form turn-on snubber. In this circuit structure, the turn-off snubber is used to limit rising rate of drain-source voltage of MOSFET and to reduce turn-off switching loss. While, the turn-on ones are used to smooth out current passing switch and to reduce turn-on switching loss. In addition, the proposed converter is operated in an interleaved fashion to reduce output current ripple. Compared with the counterparts of conventional converter topologies, the proposed converter has the merits of less component counts, higher efficiency, small size, and they are easier to implement. Measured results obtained from a prototype flyback converter have verified the feasibility.
