摘要
根据锂离子动力电池电动汽车车载充电的要求,提出了一种多组单元串联的充电电源结构,针对单端正激式充电单元主电路,基于电流型控制器UC3845设计了充电单元控制系统,着重介绍了电流检测内环、恒流-恒压输出特性控制外环的工作原理.
This paper presents a novel configuration of multi-charging units, according to the charging appeal of vehicles with the lithium-ion battery. The control system of charging unit based on UC3845 has been designed for the main circuit of single-ended forward charging unit. The principle of inner-loop for current detecting and outer loop for the control of character of constant current/constant voltage has been introduced in details.
