介绍了一种以单片机为核心的智能化高精度直流稳压电源的设计，通过集成有A/D、

D/A的单片机、三端稳压源、霍尔传感器和上位机组成闭环系统，实现高精度宽范围可调稳

定电压的输出，特别适用于各种有较高精度要求的场合，该电源工作可靠，性能良好，现已

成功用于某导弹遥测系统测试设备。-Abstract：The design was introduced which make single－chip microcomputer as the core of the intelligent high－precision

DC power supply， this closed－loop system is composed of integrated A/D， D/A of the microcontroller、three－terminal

regulator source、Hall sensors and host computer． it has achieved high－precision wide－range adjustable voltage

output， this power supply is especially suitable for a variety of occasions when it meet high precision， because the

power supply is reliable， and has good performance， it has been successfully used in test equipment named some

missile telemetry system．
