摘要
直流电源应用非常广泛, 其好坏直接影响着电气设备或控制系统的工作性能, 目前, 市场上各直流电源的基本环节大致相同,都包括交流电源、交流变压器、整流电路、滤波稳压电路等。直流电源应用非常广泛, 其好坏直接影响着电气设备或控制系统的工作性能。直流稳压电源是电子技术常用的设备之一,广泛的应用于教学、科研等领域。本设计AC-DC多路直流电压输出电源设计,不仅在稳定性可靠性上引入桥式整流、电容滤波,同时增加多路输出改善以往单路输出转换效率低的问题。并且还引入单片机AT89S52控制,使其在功能上具有一定智能化。在硬件方面,除了变压器外,还将使用LED数码管来进行显示。目前,电源以小型、轻量和高效率的特点被广泛应用于以电子计算机为主导的各种终端设备、通信设备等几乎所有的电子设备,是当今电子信息产业飞速发展所不可缺少的。

ABSTRACT
The rapid development of electronic technology, the DC power is widely used, have a direct impact on the electrical equipment or the control system performance, at present, the DC power supply on the market in virtually the same as the basic aspects, including the exchange of power, AC adapter, converter, filter regulator circuit. DC power is widely used, have a direct impact on the electrical equipment or the control system performance. DC power supply electronic technology is one of monly used equipment, widely used in teaching, research and other fields. In this design the power of AC-DC multiplexer direct current output voltage is not only import the Bridge rectifier and capacitor filter but also it add multiplexer of output enhance the simple output diversion efficiency , and import the AT89S52 control of its functions on a certain intelligence. In terms of hardware, in addition to transformers, will be used to control LED digital display. At present, the power source develop in small part, the featherweight and the high efficiency's characteristic is widely applied in by the electronic accounting machine as the leading each kind of terminal device, munication facility and so on nearly all electronic installation, the electronic information industry can not lake of it in today development.
Keywords: transformers, Bridge rectifier, capacitor filter, LED,power supply
