具有极低开关电压应力的全软开关超高升压变换器

In this article, a fully soft-switched ultra-high-voltage gain converter with very low switch voltage stress is presented. To achieve ultra-high-voltage gain and very low switch voltage stress, two phases of a high step-up boost converter based on coupled inductors and switched capacitors are combined. In this converter, the main and auxiliary switches operate at zero-voltage switching (ZVS) and a...
