具有降低元件应力的软开关双向升降压部分功率变换器

This article introduces a step-up/down series partial power converter (S-PPC) based on isolated current-source dc–dc converter topology. The proposed S-PPC exploits the most important feature of the used current-source topology, such as the capability to operate with both voltage polarities in the series port to decrease its rated power. Other advantages include soft switching in the entire operat...
