一种具有有源软开关和电压钳位的可再生能源系统高升压DC-DC变换器

A novel high step-up dc-dc converter with a coupled inductor and a switched capacitor is proposed in this paper, which is widely used in the renewable energy system as the front-end stage for low voltage sources. The combinational employment of the switched capacitor and the coupled inductor makes high voltage gain achievable without extreme duty cycle, resulting in reduced voltage stress on power...
