简易数控直流电源

摘要：本实验设计了一个以单片机89C51为基本控制核心的简易数控直流电源。.该设计包括直流电源输入及输出两部分，可完成0~15V之间各不同幅值的电压的输出，能够预置数，能够自动扫描输出电压并直接显示到LED数码显示管上，并可扩展输出三角波等波型。其中电压输出部分，既可手动的每按”+””-”键一下进行每0.1V大小的上下调整，也可长按”+””-”键使其自动的递增或者递减，直到需要的数值。预置数时用切换键切换预置个位或小数位，按”+””-”键进行微调。单片机编程部分是基于WAVE6000软件上设计，并在实物上进行仿真。.该系统具有抗干扰性能好，可靠性高，及最终输出电压值与真实显示值精确度较高等优点。

-DC Power Abstract : The experimental design of a 89 C51 microcontroller to control the basic core of the NC simple DC power supply. . The design includes DC power input and output of two parts. be completed between 0 ~ 15V different amplitude of the output voltage to a few preset, can automatically scan and output voltage direct digital LED display to demonstrate, can expand output triangular wave-wave. Which part of the output voltage can manually by each "" "-" button for about every 0.1 V size of the next adjustment, can be set at a "" "-" key to make it an automatic increase or decrease until the required values. Preferences to use a few key switching Preferences switch-digit or decimal point and click "," the "-" key to fine-
