一种基于T型DAB的高效率隔离式直流-直流-交流三端口变换器

This article proposes a high-efficiency isolated dc–dc–ac three-port converter (TPC) intended for residential photovoltaic-battery systems. The TPC is derived from a dual active bridge based dc–ac converter. Its dc-side provides two bidirectional dc ports by sharing the full-bridge topology, while its ac-side enables direct ac-load connection via a unique T-type half-bridge structure. Due to the s...
