| Abstract: | In order to achieve DC regulated power supply output voltage NC adjusting,using single-chip AT89S51 design for the regulation of regulated power supply and using AT89S51 as the core, power control circuit designs the d/a conver- sion,amplification,the voltage regulator and system hardware such as power circuit. There are many advantages of a brief,quick response, good stability, high efficiency and over current protection for designed numerical control power. Tested by an experiment,it has adjustable output voltage 0h 18 V, stepping value as 0.05V, the error as less than 0. 1%, the adjustment rate of output voltage as 0.05%. |
