| Abstract: | With the development of combination technique between power electronic and MCU, researches on regulated power supply through MCU interest many researchers. Due to its good properties, regulated DC Power supply based on MCU can control energy consumption of electrical equipments, and gets good reputation from engineers. The system uses AT89s51MCU as main eontrbller, AD7543 as control module of output voltage to adjust output DC voltage. With keyboard input technology as the system＇s man-machine interface, switch and display of output voltage signal by nixie tube, voltage step up to 0.1V, the range of DC voltage supply is greatly improved, and intelligent regulation of DC supply and control are available. |
