| Abstract |
This paper proposes converter that new soft switching active snubber circuit is added, the resonance energy return to life rate doing maximum whole efficiency increase. Proposed converter adds auxiliary switch and resonance inductor, resonance capacitor, two diodes to existing converter, all switch elements play turn-on/turn-off under soft switching condition and minimized switching losses. Conduction loss department is that watch layer bringing back to life resonance energy by input perfectly. These result proved through simulation and an experiment. |
