Design of Supervision Software for Programmable Power Supply Based on Virtual Instrument

Based on the development environment of virtual instrument language,this paper completes supervision software for programmable power supply.The software enables the supervision system to control the output of the programmable power supply through GPIB and SCPI command.This paper discusses the total design idea of the supervision software,the method of program and the flow of power control.With the advantages of modularization design and friendly UGI,the software could be conveniently transplanted to other testing systems for output control,signal monitoring,the parameter setting of programmable power supply.
