基于STC单片机的智能数控电源

Intelligent CNC Power Based on STC Single Chip

介绍了以STC89C52RC、STC12C5A60S2单片机为控制中心的智能电源系统。该系统利用单片机的智能性和灵活性设计了一款集恒压、恒流、恒压恒流于一体的智能电源,可以根据负载的变化及时调整电源的输出,以获得较好的输出特性。同时用户通过键盘设定本机的各个参数,并存入公用的EEPROM供多个单片机共享,STC12C5A60S2通过读取公共记忆体的数值,对实时的电压不断进行控制校正,以达到设定的输出精度。

This paper introduces a kind of digital intelligent power system which is based on the STC89C52RC,STC12C5A60S2 single chip.This system is an intelligent power which focuses on a set of constant voltage,constant current,and constant voltage constant current.It is produced by microcomputer＇s intelligent and flexible function and can adjust output according to changes in load,then gets the very good output characteristics in time.The users can set the parameters of the machine through the keyboard and put them into the public EEPROM for sharing with multiple SCM.
