中文摘要

本文提出了一种新型非隔离式双向DC-DC变换器,称为磁耦合Buck-Boost(MCB3)变换器。该拓扑具有非反相输出和升降压功能,其无源元件布局实现了与双有源桥(DAB)变换器等效的性能,但采用非隔离结构,在成本和功率密度方面具有潜在优势。

English Abstract

A new non-isolated dc–dc converter with non-inverting output and buck–boost operation, named magnetically coupled buck–boost bidirectional (MCB3) converter, is presented in this article. The MCB3 passive components arrangement connects the input and output ports getting an equivalent behavior to that of the dual active bridge (DAB) converter, but in a non-isolated topology. This equivalency allows...
