一种利用有源开关电感的高效率全软开关高升压DC-DC变换器

This article presents a novel dc–dc converter for high-step-up applications. The converter combines an active-switched-inductor (ASI) circuit and a snubber circuit to increase gain and provide soft switching for all semiconductor devices. With the use of a single-core coupled inductor, high voltage gain is achieved. The snubber circuit further contributes to the gain enhancement. The switches turn...
