课 程 设 计 说 明 书 程设计名称: 电子技术课程设计 题 目: 多路输出开关电源 学 生 姓 名: 专 业: 学 号: 指 导 教师: 日期:2010 年 7 月 2 日 成绩 多路开关输出电源 摘 要:在我们的身边,经常接触到很多关于电子线路的设备。在电子电路及设备中,一般都需要稳定的直流电源供电。所以直流稳压电源是电子系统中经常应用到的。本设计将通过多路输出直流稳压电源是设计说明稳压电路的工作原理和稳压的电源的指标及其测试方式。在电子线路设计中通常都需要电压稳定的直流电源供电,其往往采用交流电源经过转换得到的,其性能的好坏直接影响整个电子设备,一般电源主要由电源变压器, 整流电路,滤波电路和稳压电路四部分组成。一般地,开关电源大致由输入电路、变换器、控制电路、输出电路四个主体组成。 关键词:直流稳压电源, 电源变压器 ,整流电路,滤波电路,稳压电路。 Abstract: Around us, often exposed to a lot of equipment on the electronic circuit. Electronic circuits and devices, generally requires a stable DC power supply. Therefore, DC power supply is often applied to the electronic system's. This design will be through a multi-output DC power supply regulator circuit is designed to explain the principle and regulator of the power indicator and test methods. In the design of electronic circuits requiring voltage stability is usually DC power supply, which often use AC power through transform be of, the direct impact of their affect all electronic equipment, general power main You power transformer, rectifier, analog filter and regulator circuit composed of four parts. Keywords: DC regulated power supply , power transform, rectifying circuit,filter circuit,voltage stabilizing circuit. 目 录 1 前言 ........................................................................................................................................................ 1 1.1 设计背景 ........................................ 错误!未定义书签。 1.2 设计概述 .....
