具有零电流开关的交错式半桥反激变换器

Conventional interleaved half-bridge flyback converters can recycle the leakage energy stored in leakage inductance to clamp the voltage across the main power switches at a dc input voltage. However, such converters still suffer from high switching losses, especially turn-off losses. In this paper, a novel turn-off zero-current-transition (ZCT) circuit is proposed for reducing the turn-off switchi...
