| 摘 要： | 以AT89S52单片机为主控制器,通过键盘来设置直流电源的输出电压,设置步进等级可达0.1V,输出电压范围为0-12V,并可以显示电压的输出值。系统由单片机控制ADC0832输出所需的模拟量,再经过运算放大器进行放大,控制输出功率管的基极,随着功率管的基极电压的变化而输出不同的电压。

| Abstract: | Singlechip AT89S52 is the main controller of this system,by setting the output voltage of the power supply through a keyboard,its stepping level can reach to 0.1v,Output voltage range at 0 ～ 12V,and displaying the output voltage.The output analog signal is provided by the IC ADC0832,and is amplified by the operational amplifier,through controlling the base of output power transistor,then different voltage with the change of power transistor base pin is output. |
