开关电源的光耦首要是隔绝、供应反响信号和开关作用。开关电源电路中光耦的电源是从高频变压器次级电压供应的，当输出电压低于稳压管电压是给信号光耦接通，加大占空比，使得输出电压升高；反之则关断光耦减小占空比，使得输出电压下降。旦高频变压器次级负载超载或开关电路有毛病，就没有光耦电源供应，光耦就控制着开关电路不能起振，然后保护开关管不至被击穿焚毁。
1概述
光耦(opticalcoupler)亦称光电隔绝器、光耦合器或光电耦合器。它是以光为前言来传输电信号的器件，一般把发光器(红外线发光二极管LED)与受光器(光敏半导体管)封装在同一管壳内。当输入端加电信号时发光二极管宣告光线，光敏三极管接受光线之后就发作光电流，从输出端流出，然后完结了“电—光—电”变换。典型运用电路如下图1-1所示。
光耦的首要利益是：信号单向传输，输入端与输出端完全完结了前端与负载完全的电气隔绝，输出信号对输入端无影响，减小电路搅扰，简化电路规划，作业安稳，无触点，运用寿命长，传输效率高。光耦合器是70年代发展起来的新型器件，现已广泛用于电气绝缘、电平变换、级间耦合、驱动电路、开关电路、斩波器、多谐振荡器、信号隔绝、级间隔绝、脉冲扩展电路、数字外表、远距离信号传输、脉冲扩展、固态继电器(SSR)、仪器外表、通讯设备及微机接口中。在单片开关电源中，运用线性光耦合器可构成光耦反响电路，经过调度控制端电流来改动占空比，抵达精密稳压目的。
2光耦典型电路
常用于反响的光耦类型有TLP521、PC817等。这儿以TLP521为例，介绍这类光耦的特性。图2-1所示为光耦内部结构图以及引脚图。
TLP521的原边相当于一个发光二极管，原边电流If越大，光强越强，副边三极管的电流Ic越大。副边三极管电流Ic与原边二极管电流If的比值称为光耦的电流扩展系数，该系数随温度改动而改动，且受温度影响较大。作反运用的光耦正是运用“原边电流改动将导致副边电流改动”来完结反响，因而在环境温度改动剧烈的场合，因为扩展系数的温漂比较大，应尽量不经过光耦完结反响。此外，运用这类光耦有必要留心规划外围参数，使其作业在比较宽的线性带内，否则电路对工作参数的敏感度太强，不利于电路的安稳作业。
一般选择TL431结合TLP521进行反响。这时，TL431的作业原理相当于一个内部基准为2.5 V的电压过失扩展器（输出的电压进行过失扩展比较，然后将取样电压经过光电偶合器反响控制脉宽占空比，抵达安稳电压的目的），所以在其1脚与3脚之间，要接补偿网络。
TL431是由德州仪器出产的可控精密稳压源，什物如图2-3所示。它的输出电压用两个电阻就可以恣意的设置到从2.5V到36V范围内的任何值。该器件的典型动态阻抗为0.2Ω，在许多运用中用它代替稳压二极管，例如，数字电压表，运放电路，可调压电源，开关电源等。图2-2所示为TL431引脚摆放与运用连线图。
常见的光耦反响第1种接法。Vo为输出电压，Vd为芯片的供电电压。com信号接芯片的过失扩展器输出脚。留心左边的地为输出电压地，右边的地为芯片供电电压地，两者之间用光耦隔绝。图2-3所示接法的作业原理如下：当输出电压升高时，TL431的1脚(相当于电压过失扩展器的反向输入端)电压上升，3脚(相当于电压过失扩展器的输出脚) 电压下降，光耦TLP521的原边电流If增大，光耦的另一端输出电流Ic增大，电阻R4上的电压降增大，com引脚电压下降，占空比减小，输出电压减小；反之，当输出电压下降时，调度进程类似。
高于反相端电位的方式，运用运放的一种特性—当运放输出电流过大(超越运放电流输出才干)时，运放的输出电压值将下降，输出电流越大，输出电压下降越多。因而，选用这种接法的电路，一定要把PWM（脉冲宽度调制）芯片的过失扩展器的两个输入引脚接到固定电位上，且有必要是同向端电位高于反向端电位，使过失扩展器初始输出电压为高。图2-3所示接法的作业原理是：当输出电压升高时，原边电流If增大，输出电流Ic增大，因为Ic现已超越了电压过失扩展器的电流输出才干，com脚电压下降，占空比减小，输出电压减小；反之，当输出电压下降时，调度进程类似。
常见的第3种接法，如图2-4所示。与第一种底子类似，不同之处在于多了一个电阻R6，该电阻的作用是对TL431额外注入一个电流，避免TL431因注入电流过小而不能正常作业。实际上如恰当选取电阻值R3，电阻R6可以省掉。调度进程底子上同1接法一起。
常见的第4种接法，如图2-4所示。该接法与第2种接法类似，差异在于com端与光耦第4脚之间多接了一个电阻R4，其作用与第3种接法中的R6一起，其作业原理底子同接法2。
反响方法1、3适用于任何占空比（接通时间与周期之比）情况，而反响方法2、4比较适合于在占空比比较小的场合运用。
