摘要
随着时代进步,电子科学技术日新月异的高速发展,电子产品已成为人们日常生产生活中的必需品,现代化电子产品各种性能提高的同时,对其电源性能要求也越来越高。针对传统电源只能输出单一电压、电压稳定度不高的问题,设计了一种数控直流电源,本系统由AT89S52单片机作为控制器核心,通过键盘控制电路输出并在LCD上显示输出电压值,从而实现数控电源输出。该电源设计具有相对简单、操作方便、效率高、性能稳定等优势。
With the progress of the times and the rapid development of electronic science and technology,electronic products have become necessities in people’s daily production and life.While the various performances of modern electronic products have improved,their power supply performance requirements have also become higher and higher.Aiming at the problem that the traditional power supply can only output a single voltage and the voltage stability is not high,designed a numerically controlled DC power supply.This system uses the AT89S52 microcontroller as the controller core.It realizes numerical control power output though the keyboard control circuit and displays the output voltage value on the LCD.The power supply design has the advantages of relatively simple,convenient operation,high efficiency,and stable performance.
