	1概述

        

        
	光耦(opticalcoupler)亦稱光電隔絕器、光耦合器或光電耦合器。它是以光為前言來傳輸電信號的器件，一般把發光器(紅外線發光二極管LED)與受光器(光敏半導體管)封裝在同一管殼內。當輸入端加電信號時發光二極管宣告光線，光敏三極管接受光線之后就發作光電流，從輸出端流出，然后完結了“電—光—電”變換。典型運用電路如下圖1-1所示。

        

        
	光耦的首要利益是：信號單向傳輸，輸入端與輸出端完全完結了前端與負載完全的電氣隔絕，輸出信號對輸入端無影響，減小電路攪擾，簡化電路規劃，作業安穩，無觸點，運用壽命長，傳輸效率高。光耦合器是70年代發展起來的新型器件，現已廣泛用于電氣絕緣、電平變換、級間耦合、驅動電路、開關電路、斬波器、多諧振蕩器、信號隔絕、級間隔絕、脈沖擴展電路、數字外表、遠距離信號傳輸、脈沖擴展、固態繼電器(SSR)、儀器外表、通訊設備及微機接口中。在單片開關電源中，運用線性光耦合器可構成光耦反響電路，經過調度控制端電流來改動占空比，抵達精密穩壓目的。

        

        
	 

        

        
	2光耦典型電路

        

        
	常用于反響的光耦類型有TLP521、PC817等。這兒以TLP521為例，介紹這類光耦的特性。圖2-1所示為光耦內部結構圖以及引腳圖。

        

        
	TLP521的原邊相當于一個發光二極管，原邊電流If越大，光強越強，副邊三極管的電流Ic越大。副邊三極管電流Ic與原邊二極管電流If的比值稱為光耦的電流擴展系數，該系數隨溫度改動而改動，且受溫度影響較大。作反運用的光耦正是運用“原邊電流改動將導致副邊電流改動”來完結反響，因而在環境溫度改動劇烈的場合，因為擴展系數的溫漂比較大，應盡量不經過光耦完結反響。此外，運用這類光耦有必要留心規劃外圍參數，使其作業在比較寬的線性帶內，否則電路對工作參數的敏感度太強，不利于電路的安穩作業。

        

        
	一般選擇TL431結合TLP521進行反響。這時，TL431的作業原理相當于一個內部基準為2.5 V的電壓過失擴展器（輸出的電壓進行過失擴展比較，然后將取樣電壓經過光電偶合器反響控制脈寬占空比，抵達安穩電壓的目的），所以在其1腳與3腳之間，要接補償網絡。

        

        
	 

        

        
	TL431是由德州儀器出產的可控精密穩壓源，什物如圖2-3所示。它的輸出電壓用兩個電阻就可以恣意的設置到從2.5V到36V范圍內的任何值。該器件的典型動態阻抗為0.2Ω，在許多運用中用它代替穩壓二極管，例如，數字電壓表，運放電路，可調壓電源，開關電源等。圖2-2所示為TL431引腳擺放與運用連線圖。

        

        
	 

        

        
	常見的光耦反響第1種接法。Vo為輸出電壓，Vd為芯片的供電電壓。com信號接芯片的過失擴展器輸出腳。留心左邊的地為輸出電壓地，右邊的地為芯片供電電壓地，兩者之間用光耦隔絕。圖2-3所示接法的作業原理如下：當輸出電壓升高時，TL431的1腳(相當于電壓過失擴展器的反向輸入端)電壓上升，3腳(相當于電壓過失擴展器的輸出腳) 電壓下降，光耦TLP521的原邊電流If增大，光耦的另一端輸出電流Ic增大，電阻R4上的電壓降增大，com引腳電壓下降，占空比減小，輸出電壓減�。环粗�，當輸出電壓下降時，調度進程類似。

        

        
	 

        

        
	高于反相端電位的方式，運用運放的一種特性—當運放輸出電流過大(超越運放電流輸出才干)時，運放的輸出電壓值將下降，輸出電流越大，輸出電壓下降越多。因而，選用這種接法的電路，一定要把PWM（脈沖寬度調制）芯片的過失擴展器的兩個輸入引腳接到固定電位上，且有必要是同向端電位高于反向端電位，使過失擴展器初始輸出電壓為高。圖2-3所示接法的作業原理是：當輸出電壓升高時，原邊電流If增大，輸出電流Ic增大，因為Ic現已超越了電壓過失擴展器的電流輸出才干，com腳電壓下降，占空比減小，輸出電壓減�。环粗�，當輸出電壓下降時，調度進程類似。

        

        
	常見的第3種接法，如圖2-4所示。與第一種底子類似，不同之處在于多了一個電阻R6，該電阻的作用是對TL431額外注入一個電流，避免TL431因注入電流過小而不能正常作業。實際上如恰當選取電阻值R3，電阻R6可以省掉。調度進程底子上同1接法一起。

        

        
	常見的第4種接法，如圖2-4所示。該接法與第2種接法類似，差異在于com端與光耦第4腳之間多接了一個電阻R4，其作用與第3種接法中的R6一起，其作業原理底子同接法2。

        

        
	 

        

        
	反響方法1、3適用于任何占空比（接通時間與周期之比）情況，而反響方法2、4比較適合于在占空比比較小的場合運用。

        

        
	3、小結

        

        
	開關電源的光耦首要是隔絕、供應反響信號和開關作用。開關電源電路中光耦的電源是從高頻變壓器次級電壓供應的，當輸出電壓低于穩壓管電壓是給信號光耦接通，加大占空比，使得輸出電壓升高；反之則關斷光耦減小占空比，使得輸出電壓下降。旦高頻變壓器次級負載超載或開關電路有毛病，就沒有光耦電源供應，光耦就控制著開關電路不能起振，然后保護開關管不至被擊穿焚毀。
