摘要
Boost电路和半桥、全桥电路相结合的电流馈电DC-DC变换器被广泛地使用在UPS、燃料电池等低输入电压、高输出电压的系统中。文中介绍了一种新型的有源钳位电路,在实现有源钳位的同时对所有的开关管实现了ZVS开通,提高了变换器的效率。
The combination of boost and half-bridge or/and full bridge current-fed DC-DC converter are widely used in UPS, fuel-cell systems in which the input voltage is much lower than the output voltage. An active clamp circuit is proposed in the paper. And the circuit can achieve the ZVS of all power switches. It＇s easy to achieve the high efficiency,
