戽斗式大功率斩波器

BAILING BACKET TYPE OF LARGE POWER CHOPPER

介绍了戽斗式斩波器或ＤＣ／ＤＣ变换器的工作原理，这种斩波器结构简单，可使电路中的开关器件在零电流状态下关断，特别适宜于大功率条件下的直流变换，并具有优良的性能价格比，易于实现模块化。在理论上导出了这种斩波器的各项性能指标与其电路参数间的关系。

A new developed chopper or converter,named bailing bucket type of chopper, is developed.It is characterized by simplicity in circuit structure and high efficiency.The switcher of its main circuit can be switched off under zero current state based on its working principle. Therefore,it is suitable for high power application. It has a competitive performance price ratio and is feasible to be made as modules for building more powerful unit. Some relative formulas of performance indexes for the chopper and its circuit parameters are developed theoretically and proved experimentally.
