一种用于电动汽车充电的集成电池储能/可再生能源与电网的98.3%高效率多端口多向功率流系统

This article proposes an efficient and optimized 3-$\phi$ unfolding-based grid-tied ac–dc multiport system for integrating battery storage or renewable energy sources with the grid for electric vehicle (EV) charging applications. Compared to conventional approaches, the proposed architecture reduces the number of power conversion stages and magnetic components, thereby enhancing power density and ...
