具有最小开关电压应力的非隔离高升压DC-DC变换器

A new high-step-up dc-dc converter topology combining a charge pump mechanism with a standard inductor-based buck cell is presented here. Its main advantages are minimum switch voltage stress, given by the input voltage, and reduced energy in the magnetic element compared to a conventional boost converter designed for the same voltage gain. The proposed topology is derived through a modification o...
