一种具有低电压应力和零电压开关的非隔离高降压DC-DC变换器

This article introduces a general method to modify the traditional buck converter to become a high step-down dc–dc converter, which has a lower voltage gain without changing the voltage stress of switches. From the analysis, an auxiliary circuit is proposed to implement this method. In addition, triangular conduction mode operation is also analyzed to derive zero-voltage switching (ZVS) model of t...
