一种具有两个双向端口且元件更少的非隔离三端口DC-DC变换器

A Nonisolated Three-Port DC–DC Converter With Two Bidirectional Ports and Fewer Components

语言:

中文摘要

本文提出了一种新型非隔离三端口变换器,通过优化功率流图及拓扑排列,显著减少了元件数量。与现有研究多仅包含一个双向端口不同,该拓扑设计了两个双向端口,以更好地满足多源能量管理与协同应用需求。

English Abstract

This article presents a new nonisolated three-port converter with reduced component count compared with existing reported topologies. This is achieved by developing different power flow graphs and selecting the most appropriate converters arrangement. In addition, as compared to only one bidirectional port in most reported studies, this article considers two bidirectional ports to accommodate appl...
