Dab tsi yog Anti rov qab diode nyob rau hauv lub hnub ci zog?

一, cov tub ntxhais muaj nuj nqi ntawm anti rov qab diode: "Valve Kev Nyab Xeeb" rau Unidirectional Tswj Tam Sim No
1. Tiv Thaiv Rov Qab Tawm Ntawm Lub Roj Teeb
Thaum lub hnub ci cell array nres generating hluav taws xob nyob rau cov roj teeb, qhov hluav taws xob ntawm lub roj teeb tuaj, ua rau muaj cov vaj huam sib luag tam sim no. Anti rov qab txoj kev diodes tau txuas nyob rau hauv Circuit Court, siv lawv cov unidirectional conduction los tsuas yog cia cov roj teeb rau lub roj teeb, thaiv cov ntws rov qab. Piv txwv li, hauv cov ntaub ntawv ywj pheej thaij duab, yog tias anti rov qab despes, tab sis kuj ua rau lub hnub ci tsis zoo, tsis yog hlawv tawm rau cov khoom siv tam sim no, ua kom luv rau cov khoom siv lub neej tam sim no.
2. SUPPpress Backflow tam sim no ntawm cov ceg ntawm cov array
Nyob rau hauv loj photovoltaic lub hwj chim nroj tsuag, lub roj teeb array feem ntau yog muaj ntawm ntau cov ceg sib piv. Vim muaj qhov sib txawv ntawm kev teeb pom kev zoo thiab kev ua haujlwm sib xyaw ntawm cov ceg sib txawv, cov zis voltage yuav tsis zoo ib yam. Qhov tam sim no los ntawm qhov siab - voltage ceg yuav ntws rov qab mus rau qhov kev cuam tshuam tag nrho ntawm lub siab tam sim no tej zaum yuav raug puas vim vim kev kub ntxhov hauv ib cheeb tsam. Anti rov qab txoj kev diodes tau txuas nyob rau hauv txhua ceg kom ntseeg tau tias tsuas yog ntws los ntawm lub siab voltage kawg, tsis txhob cuam tshuam ntawm kev cuam tshuam ntawm nruab nrab ntawm ceg. Piv txwv li, lub chaw nres tsheb 10mw hluav taws xob nce los ntawm kev ua haujlwm hauv 3% thiab cov hluav taws xob txhua xyoo los ntawm kwv yees li 300000 los ntawm kev txhim kho anti thim rov qab rau txhua ceg.
3. Kev tiv thaiv dhau los thiab kev tiv thaiv ntawm thermal khiav khiav
Thaum cov roj teeb lossis kev ua haujlwm tsis zoo, lawv cov zis hluav taws xob yuav poob nrawm, ua "load" hauv Circuit Court. Txij ntawm no, tus bypass diodes kev sib txuas ntawm ob xaus ntawm cov kev ua txhaum, zam kev puas tsuaj rau lwm yam kev puas tsuaj vim yog overvoltage. Piv txwv li, hauv photovoltaic cov nroj tsuag fais fab nroj tsuag hauv thaj chaw suab puam, cov hniav nyiaj xuab zeb yuav ua rau muaj kev txo hwj chim ntawm qee cov khoom siv. Bypass Uiodes tuaj yeem nthuav tawm cov neeg ua haujlwm tsis raug hluav taws xob thiab tiv thaiv cov thermal khiav tawm ntawm kis mus rau tag nrho cov array.
2, Xaiv cov qauv rau anti thim rov qab diiodes: kev kos duab ntawm ntsuas ntsuas thiab raug nqi
1. Khab parameter txuam
Qhov siab tshaj plaws rau pem hauv ntej (yog tias): nws yuav tsum muaj ntau dua qhov kev ua haujlwm ntau tshaj plaws ntawm lub system. Piv txwv li, hauv 100kw photovoltaic, yog qhov kev ua haujlwm ntau tshaj plaws yog 200a, diodes nrog yog li ntau dua lossis sib npaug los ntawm 250 leej neeg yuav tsum tau xaiv kom muaj kev nyab xeeb npoo.
Rov qab Peak voltage (VRRM): Nws xav tau ntau dua qhov kev thim rov qab ntau tshaj plaws ntawm cov kab ke. Nyob rau hauv high {- cheeb tsam, vim qhov hluav taws xob siab dua, qhib Circuit Court yuav mus txog rau ntau dua 1000V. Nyob rau lub sijhawm no, diodes nrog VRRM ntau dua los yog sib npaug rau 1200V yuav tsum tau xaiv.
Kev tso hluav taws xob zoo (VF): cuam tshuam ncaj qha rau kev ua tau zoo. Tus VF ntawm cov paai rectifier diodes yog hais txog 0.7v, thaum lub VF ntawm Schottky diodes yuav muaj tsawg li 0.3V. Nyob rau hauv cov nroj tsuag loj loj, siv schottky diodes tuaj yeem txo qis kab poob thiab nce ntau tiam neeg.
2. Cov khoom siv thiab cov qauv ua kom zoo
Fast rov qab ua Diode (FRD): haum rau high- zaus hloov mus rau lub sijhawm (TRR) tsuas yog siv ob peb lub sijhawm rov qab los, uas tuaj yeem txo cov khoom poob. Hauv daim phiaj sib txuas photovoltaic inverters, FRD tuaj yeem txhim kho kev ua tau zoo hloov tau 98%.
Silicon carbide (sic) diodes: cim los ntawm kev tiv thaiv siab tiv taus, qis tsis kam. Nyob rau hauv high {- sov suab puam ntawm cov sic dic
Modular tsim: kev sib xyaw ua ke ntau dodes rau tib lub pob tuaj yeem yooj yim muab cov txheej txheem hluav taws xob thiab txo parasitic inductance. Piv txwv li, MDK250AA0600V DIES MODULE tau pib los ntawm qee hom lag luam muaj 40% txo hauv cov khoom siv txiav txim siab thiab 30% nce hauv kev teeb tsa kev txhim kho.
3, Raug Daim Ntawv Teev Npe Li Qub: Pab them tag nrho los ntawm tsev neeg rau kev lag luam thiab ua lag luam
1. Tsev Neeg photovoltaic system
Hauv cov rooftop me me photovoltaic tshuab, Anti Rov Qab Uiodes feem ntau yog feem ntau ua ke hauv lub photovoltaic maub los. Piv txwv li, qee hom tswj hwm tsev ntawm 5KW cov kev tswj hwm tsev siv cov yam ntxwv Sciodes, uas nws cov yam ntxwv tsawg dua los ntawm kev ua tau zoo los ntawm 1.5% thiab nce siab dua txhua xyoo txhawb nqa raws li xyoo 200 degrees. Nyob rau tib lub sijhawm, lub tsim tsa - hauv kev tiv thaiv kev tiv thaiv kev ua haujlwm ntawm cov khoom siv hluav taws xob, txuas lub sijhawm lav tau rau 5 xyoos.
2. Kev lag luam thiab cov lag luam photovoltaic fais fab nroj tsuag
Hauv cov chaw nres tsheb loj, tiv thaiv kev thim rov qab diodes tau siv dav hauv cov khoom tseem ceeb xws li cov thawv sib xyaw thiab inverters. Piv txwv li, ib qho chaw nres tsheb muaj 20mw Ib qho ntxiv, los ntawm kev soj ntsuam qhov kub ntawm cov diode hauv tiag tiag- lub sij hawm tuaj yeem muab cov kev ua txhaum thaum ntxov thiab tsis muaj peev xwm ua tsis tiav.
3. Cov ntawv thov ib puag ncig tshwj xeeb
Nyob rau hauv cov cheeb tsam txias txias (xws li Arctic lub voj voog), tsawg kub tej zaum yuav ua rau cov VF kom nce, cuam tshuam kev ua haujlwm. Qhov qis - kub schottky diode tsim los ntawm qee hom ntawm {5} Ib puag ncig, ua haujlwm ruaj khov ntawm cov txheej txheem huab cua. Hauv ntug dej ntawm ntug dej photshore, Diode modules nrog anti-corrosion txheej corrosion thiab muaj ib lub neej dhau los ntawm 25 xyoos.
4, Kev Lag Luam Cov Qauv thiab Yav Tom Ntej Txawv: Technology Iyeration Drives Kev Nyab Xeeb Kev Ruaj Ntseg
1. Lub teb chaws tus qauv thiab daim ntawv pov thawj yuav tsum muaj
Tus lej Suav "tsim qauv rau photovoltaic fais fab tuag uas yuav tsum tsis txhob tsawg tshaj li 1.5 npaug ntawm qhov ntsuas hluav taws xob ntawm lub cev. In addition, the product needs to pass international certifications such as T Ü V and UL to ensure compliance with mandatory standards such as safety and environmental protection.
2. Raws li kev txawj ntse thiab kev sib koom ua ke
Nyob rau hauv lub neej yav tom ntej, anti rov qab diodes yuav txhim kho mus rau kev txawj ntse thiab kev sib koom ua ke. Piv txwv li, los ntawm kev daws teeb meem kub thiab kev sib txuas lus tau upload lawv cov xwm txheej ua haujlwm hauv tiag tiag- lub sijhawm rau huab, ua txhaum kev tshuaj xyuas cov chaw taws teeb thiab kev ua txhaum Nyob rau tib lub sijhawm, kev tsim qauv sib xyaw nrog cov khoom siv fais fab xws li Mosfets thiab IGBTS tuaj yeem txo cov khoom loj thiab cov nqi qis dua.
3. Kev tawg hauv cov ntaub ntawv tshiab thiab cov txheej txheem
Nrog rau kev paub tab ntawm peb -}} tiam semiconductor cov ntaub ntawv (ganium nitride (gan) dongs yuav tsum tau siv dav hauv lub photovoltaic. Nws lub sijhawm rov qab rov qab tuaj yeem ua kom luv dua li 10 nanoseconds, muab kev txhawb nqa tseem ceeb rau cov khoom siv hluav taws xob ua kom muaj txiaj ntsig zoo.
