XaivicalCoupler
Tus kho qhov muag txuas (tseem hu ua OC) kuj tseem hu ua opto-isolator lossis optocoupler, raug xa mus ua optocoupler. Nws yog cov khoom siv uas xa cov hluav taws xob qhia los ntawm kev ua kom pom kev. Feem ntau, ib lub chaw taws teeb (duab teeb ci qhia teeb ci (LED)) thiab lub teeb txais hluav taws xob (photosensitive semiconductor tube) tau ntim rau hauv tib lub pob. Thaum lub davhlau ya nyob twg muaj hluav taws xob, lub chaw taws teeb ua kom muaj lub teeb ci, thiab tom qab tau txais lub teeb, photocurrent tsim tawm thiab ntws tawm ntawm cov zis kawg, yog li paub qhov" hluav taws xob-kho qhov muag-hluav taws xob" hloov dua siab tshiab. Lub tshuab optocoupler uas khub niam txiv cov lus taw qhia rau cov zis kawg nrog lub teeb ua qhov nruab nrab, vim nws qhov me me, lub neej ntev, tsis muaj kev sib cuag, muaj zog tiv thaiv kev cuam tshuam, muaj peev xwm tiv thaiv ntawm cov zis thiab cov lus qhia, ib-txoj kev xa ntawm cov paib, thiab lwm yam. Dav siv hauv kev ua haujlwm hauv circuits. Optocouplers tuaj yeem muab faib ua cov optocouplers nonlinear thiab kho qhov tso cai.
Tus khoos phis tawj xa cov hluav taws xob qhia hauv lub teeb ua lub nruab nrab. Nws muaj qhov sib cais zoo rau cov tswv yim thiab tawm hluav taws xob cov cim, yog li nws tau siv dav hauv ntau lub voj voog. Optocouplers tau dhau los ua ib qho ntawm ntau thiab ntau yam khoom siv optoelectronic. Tus pas ntsuas hluav taws xob txuas feem ntau muaj peb ntu: kev hloov kho lub teeb, txais tos lub teeb, thiab teeb liab ua kom nrov nrov. Cov hluav taws xob teeb liab nkag mus rau lub teeb hluav taws xob tso tawm (LED) ua rau muaj qee qhov hluav taws xob ntawm lub teeb, uas tau txais los ntawm photodetector los tsim photocurrent, uas ntxiv tau txuas ntxiv thiab tsim tawm. Qhov no ua tiav cov hluav taws xob hluav taws xob-kho qhov muag, thiaj li ua haujlwm tau raws li kev tawm tswv yim, tsim tawm, thiab cais tawm. Txij li cov tswv yim thiab cov khoom tawm ntawm optocoupler raug cais tawm ntawm ib qho, cov hluav taws xob teeb liab kis tau muaj cov yam ntxwv ntawm tsis ua haujlwm, thiab yog li muaj hluav taws xob zoo rwb thaiv tsev thiab muaj peev xwm tiv thaiv kev cuam tshuam. Yog li, nws muaj peev xwm txhim kho tau ntau lub teeb liab-kom nrov nrov raws li lub davhlau ya nyob twg cais nyob rau hauv cov kab ntev kis cov ntaub ntawv. Raws li lub teeb liab cais interface ntaus hauv computer kev sib txuas lus digital thiab kev tswj hwm lub sijhawm, kev ntseeg tau ntawm lub koos pij tawj tau ua tau zoo heev.
Ntxiv mus, txij li lub tswv yim xaus ntawm optocoupler belongs rau cov khoom tiv thaiv tsis tshua muaj kev tiv thaiv tam sim no hom kev ua haujlwm, nws muaj muaj zog ntau hom kev ua haujlwm muaj peev xwm.
Lub tshuab pa txuas ntxiv muaj cov yam ntxwv ntawm qhov loj me, lub neej ntev, tsis muaj kev sib cuag, muaj peev xwm tiv thaiv kev cuam tshuam, cais tawm ntawm cov khoom tawm thiab cov tswv yim, thiab ib-txoj kev sib kis ntawm cov paib, thiab qee zaum nws tuaj yeem hloov xa mus, hloov pauv, tsuav thiab lwm yam. [1] Siv dav hauv hluav taws xob rwb thaiv tsev, qib hloov chaw, txuas kev sib txuas, tsav hluav taws xob, hloov hluav taws xob, ntov, ntau yam, teeb liab cais, cais tawm kev sib cais, kaw lub suab nrov, kab hluav taws xob, lub ntsuas dej ntev, Lub teeb liab kis tau tus mob, pulse amplification, solid state relay ( SSR), twj paj nruag, khoom siv sib txuas lus thiab cuam tshuam computer. Hauv cov monolithic switching power supply, optocoupler tawm tswv yim Circuit Court tuaj yeem tsim lub tsev los ntawm kev siv cov kab hluav taws xob kho qhov muag, thiab lub luag haujlwm sib luag tau hloov los ntawm kev hloov kho qhov tam sim no ntawm lub davhlau ya nyob twg kom ua tiav lub hom phiaj ntawm kev ntsuas hluav taws xob.
