网络教育学院《电源技术》课程设计题目：±5V简易直流稳压电源的设计学习中心：玉溪奥鹏层次：高起专专业：电气工程及其自动化年级：2013年春季学号：************学生：高炳成完成日期：2014年6月10日±5V简易直流稳压电源的设计内容摘要根据课设规定，设计并制作有一定输出电压调节范围和功能的数控直流稳压电源。可用于输出直流电压调节范围5~15V，纹波小于10mV输出电流为止500mA.稳压系数小于0.2。直流电源内阻小于0.5Ω。输出直流电压能步进调节，步进值为1V。由“+”、“-”两键分别控制输出电压步进增的减。该简易直流稳压电源主要包括三大部分：1.数控部分，即通过数字电路调节控制稳压电源、2.D/A变换器3.可调稳压电源。具体工作原理为：通过数字控制部分控制可逆二进制计数器，再由二进制计数器的输出输入到D/A变换器，经D/A变换器转换成相应的电压，此电压经过放大到合适的电压值后，去控制稳压电源的输出，使稳压电源的输出电压以1V的步进值增或减。I±5V简易直流稳压电源的设计目录内容摘要·····························································································I引言·····························································································1一、简易直流稳压电源相关参数·······························································2二、简易直流稳压电源工作原理·······························································2三、简易直流稳压电源电路设计·······························································23.1．整流、滤波电路·······································································23.2．可调稳压电路··········································································43.3．D/A转换器电路········································································43.4．数字控制电路··········································································53.5．辅助电源电路··········································································6四、简易直流稳压电源的相关调试····························································64.1．辅助电源的安装调试·································································64.2．单脉冲及计数器调试·································································74.3．D/A变换器电路调试··································································74.4．可调稳压电源部分调试······························································7参考文献·····························································································8II±5V简易直流稳压电源的设计引言在电子电路和电气设备中，通常都需要电压稳定的直流电源供电，直流电源。当今社会人们极大的享受着电子设
