中文摘要

针对串联电池系统中模块间均衡、负载双向连接及外部充电需独立变换器的问题,本文提出了一种用于高压串联电池储能系统的集成可重构变换器。该拓扑的主要优势在于能够通过重构实现多种工作模式,有效简化系统架构并提升高压储能系统的集成度与效率。

English Abstract

In series-connected battery systems, typically, separate converters for intramodule balancing bidirectional connection to a load and charging from an external power source are employed. In this paper, an integrated reconfigurable converter for high-voltage series-connected battery storage systems is proposed. The main advantage of the proposed converter is that it can be reconfigured to operate in...
