一种具有低输入电流纹波和宽软开关范围的高变比单开关单磁芯变换器

In this article, a novel high conversion ratio dc-dc converter suitable for photovoltaic applications is presented. Utilizing single-switch and single-magnetic core, low ripple input current and low voltage stress across the semiconductors are the major advantages of the proposed converter. In order to provide a soft-switching condition for the converter switch at a wide range of output power, a p...
