Igikorwa nyamukuru cya optocoupler mumashanyarazi atangwa ni ukumenya kwigunga mugihe guhinduranya amashanyarazi no kwirinda kwivanga.Imikorere yo guhagarika iragaragara cyane muruziga.
Ikimenyetso kigenda mu cyerekezo kimwe.Iyinjiza n'ibisohoka bitandukanijwe rwose n'amashanyarazi.Ibisohoka bisohoka nta ngaruka bigira.Ubushobozi bukomeye bwo kurwanya-kwivanga, imikorere ihamye, ntaho uhurira, ubuzima bwa serivisi ndende no gukora neza.Optocoupler nigikoresho gishya cyakozwe mu myaka ya za 70.Kugeza ubu, irakoreshwa cyane mugukwirakwiza amashanyarazi, guhinduranya urwego, guhuza interstage, guhuza ibinyabiziga, guhinduranya umuzunguruko, chopper, multivibrator, kwigunga ibimenyetso, kwigunga hagati ya interineti, kuzunguruka kwa pulse, ibikoresho bya digitale, gukwirakwiza ibimenyetso birebire, gukwirakwiza impiswi, bikomeye -igikoresho cya leta, reta ya reta (SSR), ibikoresho, ibikoresho byitumanaho hamwe na interineti ya microcomputer.Muri monolithic guhinduranya amashanyarazi, umurongo wa optocoupler ukoreshwa mugutanga ibitekerezo bya optocoupler, kandi urwego rwinshingano rwahinduwe muguhindura imiyoboro igenzura kugirango igere kumigambi yo kugenzura neza voltage.
Igikorwa nyamukuru cya optocoupler muguhindura amashanyarazi ni ukwitandukanya, gutanga ibimenyetso byerekana no guhinduranya.Amashanyarazi ya optocoupler muburyo bwo guhinduranya amashanyarazi atangwa na voltage ya kabiri ya transformateur yumurongo mwinshi.Iyo voltage isohoka iri munsi ya voltage ya zener, fungura ibimenyetso optocoupler hanyuma wongere urwego rwinshingano kugirango wongere ingufu za voltage.Ibinyuranye, kuzimya optocoupler bizagabanya urwego rwinshingano kandi bigabanye ingufu za voltage.Iyo umutwaro wa kabiri wa transformateur yumurongo mwinshi uremerewe cyane cyangwa umuzunguruko wananiranye, nta mashanyarazi ya optocoupler, kandi optocoupler igenzura umuzunguruko kugirango itanyeganyega, kugirango irinde umuyoboro utwikwa.Optocoupler isanzwe ikoreshwa na TL431.Kurwanya byombi byapimwe muburyo bukurikirana kuri 431r kugirango ugereranye nuwagereranya imbere.Noneho, ukurikije ibimenyetso byo kugereranya, kurwanya ubutaka bwa 431k impera (iherezo aho anode ihujwe na optocoupler) iragenzurwa, hanyuma hakagenzurwa umucyo wa diode itanga urumuri muri optocoupler.(hari diode isohora urumuri kuruhande rumwe rwa optocoupler na Phototransistors kurundi ruhande) ubukana bwurumuri runyura.Igenzura guhangana na CE iherezo rya transistor kurundi ruhande, uhindure chip ya LED yamashanyarazi, hanyuma uhite uhindura urwego rwinshingano rwibimenyetso bisohoka kugirango ugere ku ntego yo guhagarika ingufu za voltage.
Iyo ubushyuhe bwibidukikije buhindutse cyane, ubushyuhe bwubushyuhe bwikintu kinini ni kinini, butagomba kugerwaho na optocoupler.Inzira ya Optocoupler nigice cyingenzi cyo guhinduranya amashanyarazi.
