摘　　要：该设计主要利用可调式稳压器LM317实现直流稳压电源的正负输出可调性。整个电源主要由变压器、整流电路、滤波电路,以及稳压电路几部分组成。其体积小,稳定性好且性价比较高。主要介绍其具体实现及原理,并分析具体硬件电路的工作原理及具体实现方法。结合单片机原理以及其他相关集成电路模块的相关原理实现了直流稳压电源的显示等具体功能。经反复实验,结果表明其具有灵活的可调性,控制效果良好。该电源可广泛运用于电力电子、仪表、控制等实验场合。DC regulated power supply＇s adjustion was controlled by LM317. It was mainly composed of Transformer, Rectifier circuit, Filter circuit and Regulator circuit. The size is small, the stability is good,the Cost-effective is perfect. It＇s mainly introduced about its concrete realization and principle. And the analysis of the specific working principle of hardware circuits and ways to achieve specific. The principle of combining single-chip integrated circuits and other re- lated modules realize the relevance of the principle of a DC regulated power supply,such as the specific function of the display. It is demonstrated that its flexible adjustion and so great effect of controlling. The power can be widely applied to power electronics, instrumentation, control and other experimental occasions.
