文档介绍：毕业设计论文题目:单片机控制可调直流稳压电源的设计姓名:学号:专业班级:2013/12/1广东交通职业技术学院内容摘要本文介绍了一种基于单片机的直流稳压电源设计方案,该系统由初步整流稳压部分、单片机控制部分、DAC、稳压部分和显示部分组成。该稳压电源可步进调节、实时显示,弥补了传统稳压电源的不足,其核心技术是通过单片机控制数模转换来改变其后稳压模块的输出。利用单片机控制数模转换芯片DAC0832输出电压作为稳压电路的参考电压;单片机通过键控改变DAC0832的输出电压,作为参考电压发生改变,稳压电路调整管的压降也会相应地发生变化,从而改变输出电压。································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································································、初步稳压·································································································································································································································19设计心得参考文献附录1引言随着电力电子技术的迅速发展,直流电源应用非常
