摘要
本论文主要阐述了输出电压采用分档切换方式的高性能直流稳压电源,该电源不仅具有开关电源体积小,损耗低的优点,还具有线性电源输出电压纹波小,输出特性好的优点。并且引入单片机控制,使其在功能上具有一定智能化。众所周知,许多科学实验都离不开电,并且在这些实验中经常会对通电时间、电压高低、电流大小以及动态指标有着特殊的要求,因此,如果实验电源不仅具有良好的输出质量而且还具有多功能以及一定的智能化,那么就省去了许多不精确的人为操作,取而代之的是精确的微机控制,而我们所要做的就是在实验开始前对一些参数进行预设。本论文主要阐述了有关直流稳压电源的开关电源由于本身工作特性使得电磁干扰问题相当突出。从开关电源电磁干扰的模型入手论述了开关电源电磁兼容问题产生的原因及种类,并给出了常用的抑制开关电源电磁干扰的措施、滤波器设计及参数选择。

Abstract
This paper expounds the output voltage by means of high-performance sub-file to switch DC power supply, switching power supply of the power not only small size, low loss advantages, also has a linear power supply output voltage ripple, output characteristics of a good advantage . And the introduction of SCM, it has some intelligence in function. As we all know, many scientific experiments can not do without electricity, and often in these experiments will power the time, voltage level, current and the dynamic parameters had special requirements, therefore, if the experiment Dian Yuan not only has good output quality, but also with multiple functions, and some intelligence, then save a lot of imprecise human action and replace it with a puter control, and we need to do is to test some parameters before the start of the default. This thesis described the DC regulated power supply switching power supply, because of their characteristics make the work of ic interference has been outstanding. ic interference from the switching power supply model of the switching power supply patibility discussed the causes and types of questions, and gives monly used switching power supply ic interference suppression measures, filter design and parameter selection
