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-
