| 摘 要： | 系统以AT89C51单片机为主控制器,由电流源、DA转换、AD转换和LED数码管等模块组成。利用电流负反馈和键盘设置,实现数控直流电流源,并能将预设的电流值与实际值在数码管上交替显示,通过检测证明本系统输出电流稳定。

| Abstract: | The controller is made by AT89C51.It consists of permanent current source,D/A converter,A/D converter and LED digital code,It can realize numerical current source and the design of permanent current source by making use of negative feedbace and keyboard set up.It also can display the preserved current value and actual value in LED digital code in alternative.It can prove that the system exports steady current. |
