摘要:

介绍了一种基于AT89C51的智能稳压电源的设计方案,其核心技术是通过AT89C51控制数模转换来改变其后稳压模块的输出。该系统由整流滤波初步稳压电路部分、AT89C51控制部分、DAC和显示部分组成,该稳压电源能连续步进可调,并可实时显示,弥补了传统稳压电源的不足。

关键词: AT89C51, 稳压电源, 连续步进可调, DAC

Abstract:

This paper introduces a single-chip microcomputer-based intelligent power supply design,which uses the MCU to control digital-to-analog converters to change the voltage regulator module subsequent output.The system consists of rectifier filter preliminary regulator of the MCU control of the DAC and display components.The power supply has continuously adjustable stepping with real-time display,overcoming the shortcomings of traditional voltage regulator power supply.

Key words: AT89C51;regulated power supply;stepping and adjustable row;DAC
