The Design of Numerical Control Voltage-Stabilized Source
Base on Single-Chip Computer
ABSTRACT: With the development of the times, digital electronic technology has been popular in all of our lives, work, research, and all fields. This paper introduces a NC DC power supply, the power consists of analogue power supply, display circuit, control circuit, digital-to-analog converter and circuit amplifier. Accurately, analog power supplies voltage for chip power, the digital tube and amplifier; display circuit displays the output voltage. NC DC current source can reduce output error that caused by components aging, In terms of software it mainly uses the PID algorithm to achieve the precise control of output current. The system has good features of high reliability, small size, simple operation and friendly man-machine interface.
