摘要
为使监控电路在主电源掉电后能够正常工作,因此设计一种简单、通用、廉价的不间断直流供电单元是十分必要的。本文在研究了铅酸电池的充电常识后,描述了一种基于UC3906的充电管理电路,此电路不但能够进行高效率高精度的充电,还能完成备用电源的投入与切断。最后对开发调试过程中得到的经验进行总结。
In order to let the monitor unit keep running when the power supply missed, it is necessary to design a general-purpose, simple and cheap UPS. After studied the basic knowledge of Lead-Acid Battery charging course, this paper describes a Lead-Acid battery charger circuit, which not only achieves the high charging effective and accuracy, but also completes the shifting between the power supply and the backup battery. In the end, the paper includes the experiences that were gotten in the course of design and debug.
