串联型直流稳压电源设计报告 一、设计题目 题目:串联型直流稳压电源 二、设计任务:设计并制作用晶体管、集成运算放大器电阻、电阻器、电容组成的串联型直流稳压电源。 指标:1、输入电压: 2、输出电压:3- 6V、6-9V、9-12V三档直流电压; 3、输出电流:最大电流为1A; 4、保护电路:过流保护、短路保护。 三、理电路和程序设计: 一电路原理方框图: 二原理说明: (1)单相桥式整流电路可以将单相交流电变换为直流电; (2)整流后的电压脉动较大.需要滤波后变为交流分量较小的直流电压用来供电; (3)滤波后的输出电压容易随电网电压和负载的变化波动不利于设备的稳定运行; (4)将输出电压经过稳压电路后输出电压不会随电网和负载的变化而变化从而提高设备的稳定性和可靠性.保障设备的正常

使用; (5) 关于输出电压在不同档位之间的变换.可以将稳压电源的电 压设置为标准电压再对其进行变换.电压在档位间的调节可以通过调节电位器来进行调节.从而实现对输出电压的调节。 四:方案选择 一:变压、滤波电路 方案一和方案二的变压电路和滤波电路相同.二者的差别主要体现在稳压电路部分。 图1 变压和滤波电路 二:稳压电路 方案一:此方案以稳压管D1的电压作为三极管Q1的基准电压.电路 引入电压负反馈.当电网电压波动引起R 2两端电压的变化增大(减小)时.晶体管发射极电位将随着升高(降低).而稳压管端的电压基本不变.故基极电位不变.所以由E B BE U U U -=可知 BE U 将减小(升高)导致基极电流和发射极电流的减小(增大). 使得R 两端的电压降低(升高).从而达到稳压的效果。负电源部分与正电源相对称.原理一样。

串联型直流稳压电源设计报告 一、设计任务与要求 要求:设计并制作用晶体管和集成运算放大器组成的串联型直流稳压电源。 指标:1、输出电压6V 、9V 两档,同时具备正负极性输出; 2、输出电流:额定电流为150mA ,最大电流为500mA ; 3、在最大输出电流的时候纹波电压峰值▲V op-p ≤5mv ; 任务:1、了解带有的组成和工作原理: 2、识别的电路图: 3、仿真电路并选取元器件: 4、安装调试带有放大环节串联型稳压电路: 5、用仪器仪表对电路调试和测量相关参数: 6、撰写设计报告、调试。 二、电路原理分析与方案设计 采用变压器、二极管、集成运放、电阻、稳压管、三极管等元器件。220V 的交流电经变压器变压后变成电压值较小的电流,再经桥式整流电路和滤波电路形成直流稳压部分采用串联型稳压电路。比例运算电路的输入电压为稳定电压,且比例系数可调,所以输出电压也可以调节:同时,为了扩大输出电流,集成运放输出端加晶体管,并保持射级输出形式就构成了具有放大环节的串联型稳压电路。 1、方案比较 方案一: 先对输入电压进行降压,然后用单相桥式二极管对其进行整流,整流后利用电容的充放电效应,用电解电容对其进行滤波,将脉动的直流电压变为更加平滑的直流电压,稳压部分的单元电路由稳压管和三极管组成(如图1),以稳压管D1电压作为三极管Q1的基准电压,电路引入电压负反馈,当电网电压波动引起R 2两端电压的变化增大(减小)时,晶体管发射极电位将随着升高(降低),而稳压管端的电压基本不变,故基极电位不变,所以由E B BE U U U -=可知BE U 将

分立式串联稳压电源

第一章串联反馈型稳压电源整体简介制作串联反馈型稳压电源的目的要求 一、基本目的 此次工程训练选择使用分立式元器件构成串联反馈型直流稳压电源。学生通过实训了解相关分立式元器件的基本结构、工作原理、特性和参数以及由它们构成的串联型直流稳压电源的工作原理、原理图的设计和参数的计算、元器件的选用、计算机软件实现硬件的仿真、PCB板的设计、电路的安装和调试,最后完成达到技术指标要求的标准产品。 二、基本要求 1、依据性能指标和器件状况,设计稳压电源电子电路,并计算器件参数确定选择器件。(含散热设计); 2、以本工程训练为实例先学习Protel99SE基本知识,并运用其绘制电源sch原理图和PCB图; 3、学习Proteus知识,对本电源电路进行仿真,最终确定sch和pcb图; 4、掌握电子电路板制作的全过程,实现电源的制作; 5、测量电源相关各项技术指标,完成系统调试。 基本知识介绍 一、电源变压器知识 1.初级(Primary Winding):是指电源变压器的电源输入端。 2.次级(Secondary Winding):是指电源变压器的输出端。

3.额定输入电压U:是指电源变压器的初级所接上的电压,也就是电源变压器的工作电压。对GS变压器来说,U=230V;对BS变压器来说,U=240V。 4.空载电流I:是指电源变压器的初级接上额定输入电压U而次级不带负载(即开路)时,流过初级的电流。I与变压器的设计有关,即使是两个不同厂家生产的相同规格的电源变压器,其I也可能不同。 5.空载电压U:是指变压器初级接受上额定输入电压U次级不带负载(即开路)时,次级两端的电压。U与变压器的设计有关,即使是两个不同厂家生产的相同规格的电源变压器,其U也可能不同。 6.负载电流I:是指变压器初级接上额定输入电压U,次级接上额定负载时,流过负载的电流。 7.负载电压U:是指变压器初级接上额定输入电压U,次级接上额定负载时,负载两端的电压。 8.定输出功率P:是指变压器在额定输入电压U时的输出功率,它表示变压器传送能量的大小。一般来说,在相同频率下,P越大,变压器的尺寸越大;P相同,即使输出电压U不同,变压器的尺寸也相同,即变压器的价格也应相差无几。 由公式P=U*I可知若输出功率P一定,若输出电压U越高,则输出电流I越低。举例来说,一个输出功率P=10VA的变压器,若输出电压U=24V,则输出电流I= P/U=10VA/24V =;若U=12V,则输出电流I=。 电源变压器:将电网交流电压变为整流电路所需的交流电压,一般次级电压u2较小。 变压器副边与原边的功率比为P2/ P1=η,式中η是变压器的效率。 对于本次工程训练对电源变压器的要求主要为次级空载电压大小,额定输出功率,变压器的额定容量,所以在本次工程训练中选择的是小型单相式变压器,有四组输出线分别为7V、

The king asked his daughter how much she loved him. She said that she loved him as much as she loved 36 . Her answer made the king very happy. Salt is a simple thing, 37 it is very important. So the king thought his daughter cared a lot about him. Salt has many 38 . Our bodied need salt. If we don’t have enough, our bodies can’t work properly. We put salt on icy roads to make them 39 . We also use salt to produce other products, like paper and glass. But for many years, salt’s most important job was to 40 food. Like other living things, most bacteria (细菌) need water to live . Salt takes in plenty of water, so most bacteria cannot live 41 a salty environment. As a result, salt protects food and many other things. For much of human history, this ability has made salt 42 . Every ancient culture from Egypt to China depended on salt. Even today, the hard-working, useful people are 43 as “the salt of the earth”. For centuries, salt was also hard to 44 . Its usefulness, together with rarity (稀有) made it very expensive. Salt could even be used like 45 . In fact, the word salary (薪水) comes
