摘要
由于正激变换器的功率变压器工作在B-H曲线的第Ⅰ象限，本身又无复位能力，所以需要借助于专门的复位电路使变压器避免饱和。介绍了三种常用的复位电路和一种新颖的零电压过渡(ZVT)复位电路，并对它们的优缺点进行了比较。
The core of forward power converter is operated in the first quadrant of the B-H curve,it can not reset itself,so it must re sort to special reset scheme to keep the transformer from saturation.This paper introduces three common reset schemes and one novel zerovoltagetransition re set schemes,the merit and flaw of the four schemes are compared with one each ot her.
