一种具有堆叠倍压单元的单开关ZVS高升压DC-DC变换器

This article proposes a new single-switch high step-up dc–dc converter with soft-switching characteristics in renewable energy systems. The converter consists of a Sepic-based network integrating a build-in transformer and a voltage multiplier cell (VMC) stacked on the output. It achieves ZVS turn-on for the switch in a certain load range by designing proper components’ parameters without adding a...
