基于反激变换器的电池充电系统设计
Design of battery charging system based on flyback converter
摘要
Abstract
The flyback converter,which has the advantages of simple structure and electrical isolation,is used as the battery charging power supply.The working principles of the continuous and intermittent mode of flyback converter circuits are analyzed.The constant current charging mode and constant voltage charging mode of batteries can be realized by designing the voltage and current double closed-loop control method,and the switching between constant current charging mode and constant voltage charging mode can also be realized.The experimental results prove that the correctness of the continuous operation mode and intermittent operation mode of the flyback converter(FC),verify the feasibility and effectiveness of the application in the battery charging power supply.The switching time is less than 1 ms,the voltage fluctuation is less than 1 V.关键词
