The High Efficiency Charge Equalized System for Serially Connected VRLA Battery String using Synchronous Flyback Converter

摘要

This article presents a high efficiency charge equalized system for balancing energy in serially connected battery strings using synchronous flyback converter. The efficiency of this synchronous flyback converter is 80.1 percent. By applying this proposed converter along with DC Link Bus technique in charge equalized system, the unbalance charging problem can be eliminated. The validity of this approach can be supported by experimental result.
