Overview:
The power supply of the DC stabilized power supply is mostly AC power. When the voltage or load resistance of the AC power supply changes, the DC output voltage of the regulator will remain stable. With the development of high-precision, high-stability and high-reliability of electronic equipment, DC stabilized power supply places high demands on the power supply of electronic equipment. This paper takes the single-chip AT89C51 as the core, and constitutes a digitally controlled DC stabilized power supply that can simultaneously control 6 positive and negative outputs and has functions such as fixed point display and tour display.
