基于电芯电压均衡器的级联储能模块双向Buck-Boost变换器

Ordinary modular energy storage systems require cell- and module-level equalizers, in addition to a main bidirectional converter, increasing the system complexity and cost. This article proposes a bidirectional buck-boost converter using cascaded energy storage modules. Each module contains a cell-level equalizer with a half-bridge cell. The half-bridge cell in each module is utilized not only for...
