摘要

直流稳压电源一般由电源变压器,整流滤波电路及稳压电路所组成。变压器把市电交流电压变为所需要的低压交流电。整流器把交流电变为直流电。经滤波后,稳压器再把不稳定的直流电压变为稳定的直流电压输出。这次课程设计是在老师指导下独立查阅资料、设计、安装和调试特定功能的电子电路。综合设计实验有助于提高我们的电子工程素质和科学实验能力。直流稳压电源有很多优异特性,为获得可靠的直流电压,一个简易的办法就是将我国目前的市电电压通过一定的方法转化为我们需要的直流电。我们此次课程设计任务就是设计一个可靠的多路直流稳压电源。本设计主要采用多路输出直流稳压构成集成稳压电路,通过变压、整流、滤波、稳压过程将 220V交流电变为稳压直流电,并实现电压可在+~++12V/1A、-12V/1A、+5V/1A。

Abstract
Dc voltage source of power transformer, general rectifier voltage filter circuits and circuit. The mains ac voltage transformer to need low voltage ac. The alternating current to direct current rectifier. The filter, the unstable voltage dc voltage dc voltage output to stability. This course is designed under the guidance of teachers in independent data access, design, installation missioning of the specific function of electronic circuit. The integrated design experiments to improve our electronic engineering quality and scientific experiment ability. Dc voltage stabilizer has many excellent properties, for obtain reliable dc voltage, a simple method is to present the mains voltage through certain method into our needs. Our mission is to design the curriculum design of a reliable way of dc voltage stabilizer. This design is mainly adopts multiple output voltage dc voltage circuit, through the integration position, rectifier voltage regulator, filtering, will e voltage dc, ac 220V voltage and realize in + ~ + harmonizable fixed output voltage + 12 v/1A, -12V/1A, + 5V/1A.
