摘　　要：提出了一种新型基于饱和电抗器的零电压不对称PWM半桥变换器。它有低的开关损耗,低的导电损失,恒频控制等许多优点,并对它的工作原理和稳态电路作了分析,同时制作的一个150W、200kHz的软开关DC-DC变换器样机,证实了上述这些特点和性能。In this paper, a novel half-bridge type zerovoltage softswitching asymmetrical PWM DC-DC converter which make use of a saturable reactors is presented. It has many advantages such as lower switching losses and constant frequency controller. Its operation principle and stable circuit analysis are discussed in this paper, in the same time, these have been testified by a prototype soft-switching convert-er of 150 W-200 kHz.
