Design and Simulation of Precise 12V Automatic Recharger

本文首先描述了电子工作平台EWB的菜单和工作命令以及使用方法，其次详细论述了精确的12V自动充电器的工作原理，并对其每个模块进行了分析，此外还介绍了自动充电器的应用。最后给出了电路原理图并对其进行仿真，仿真结果表明，实测值与理论值的误差不大。

This paper firstly describes the menus and working instructions as well as the usages of the electronics workbench （EWB）, and then elaborates the working principle of the accurate 12V automatic charger and analyzes all modules of the charger, and moreover introduces its application. Finally, the schematic diagram of the circuit is given and its simulation is conducted, the simulated result shows that the error between the measured value and the theoretical value is smaller.
