摘    要:本文提出了一种新型的有源交错并联的Boost软开关电路。在boost主开关两端并联一个有源辅助开关和关断缓冲吸收电容组成的有源缓冲吸收支路。使用该拓扑结构,Boost的主开关管可以实现零电流导通和零电压关断,二极管的反向恢复电流带来的能量损耗能够大大削减。并且,在整个开关周期期间,附加的辅助开关管都是零电压开关。在理论分析的基础上,试制了1台1.2kW实验样机

关 键 词:交错并联  boost  软开关

Abstract:A new ZVS-ZCS interleaved boost converter is proposed in this paper. An active snubber branch composed of an auxiliary switch and a snubber capacitor is added in parallel with the main switch. By using this interleaved converter topology, the zero current turn-on and zero voltage turn-off of the main switches can be achieved and the reverse-recovery loss of boost diode can be reduced. In addition, the auxiliary switches are the ZVT during the whole switching transition. A prototype of boost converter rated at 1.2kW has been built to conform the effectiveness of the converter.
Keywords:interleaved  boost  soft switching
