Ukubaluleka kwama-photovoltaic diode ekukhiqizeni amandla elanga

Ochungechungeni lwesikwele lwamaseli elanga, i-diode iyithuluzi elivame kakhulu, i-diode evame ukusetshenziswa ngokuyisisekelo i-silicon rectifier diode, ekukhethweni kwezicaciso zokulondoloza imingcele, ukuvimbela ukulimala kokuphuka.Ngokuvamile, i-voltage ehlehliswayo ephezulu ehlehlayo kanye nenani eliphezulu lokusebenza lamanje kufanele libe ngaphezu kwezikhathi ezi-2 ze-voltage ephezulu yokusebenza kanye namandla asebenzayo.Kunezinhlobo ezimbili eziyinhloko zama-diode ezinhlelweni ze-photovoltaics.

I-Diode yokuvimbela ukushaja okuhlehlayo (ukuvikela ukuhlehla kwamanje)

Omunye wemisebenzi ye-Diode yokuvimbela ukuvimbela ukushaja okubuyela emuva (ukuvimbela ukushaja ukuhlehla) ukuvimbela ukusebenza kweseli yelanga ukuthi iguqulwe kuseli yelanga noma i-square array lapho iseli yelanga noma i-square array ingakhiqizi ugesi. indima isendaweni yebhethri, ukuvimbela okwamanje phakathi kwamagatsha amalungu afanayo ahlehliswe.Lokhu kungenxa yokuthi i-voltage ephumayo yegatsha ngalinye ochungechungeni ayikwazi ukulingana ngokuphelele, kuhlale kunomehluko phakathi kwe-voltage ephezulu nephansi yegatsha ngalinye, noma i-voltage ephumayo yegatsha yehliswa ngenxa yephutha legatsha elilodwa, shading. , njll. , amandla amanje egatsha lamandla kagesi aphezulu azogeleza aye egatsheni lamandla kagesi aphansi futhi anciphise ngisho nesamba sevolthi yokukhiphayo yohlelo lwesikwele.Lesi simo singagwenywa ngokuxhuma ama-anti-back-filling diode ochungechungeni egatsheni ngalinye.

I-Slocable'sI-Anti-Reverse Diodeine-voltage elinganiselwe engu-1600V, i-voltage yokuhlukanisa kagesi efika ku-3100V phakathi kwe-chip ne-substrate, i-glass passivated chip edayisiwe, izici ezinhle kakhulu zokushisa namandla okuhamba ngamabhayisikili, kanye nama-silicon carbide diode, kunokusetshenziswa kwamandla we-diode evamile angaphezu kuka-15. %.Ikalwe okwamanje kufika ku-55 A. Uma isistimu yakho inezilinganiso zamanje ezingaphezu kuka-12A, le diode iyanconywa ukuvikela izingxenye zakho.

I-Bypass diode

Lapho amamojula amaseli elanga engeziwe exhunywe ochungechungeni ukuze akhe igatsha lohlu lwamaseli noma uhlu lwamaseli, ama-diode eyodwa (noma amabili noma amathathu) adinga ukuxhunywa ngokuphambana okuphambene kumatheminali okukhiphayo okuhle nokubi kwephaneli ngayinye, le diode. , exhunywe ngokuhambisana kuzo zombili iziphetho zoMkhandlu, ibizwa ngokuthi i-bypass diode.

Iqhaza lama-bypass diode ukuvimbela ingxenye noma ingxenye yengxenye ohlwini oluyisikwele ukuthi ifakwe umthunzi noma imiswe ekukhiqizeni amandla uma kwenzeka ukwehluleka, uchungechunge lwamanje lwezingxenye ludlula izingxenye ezinephutha futhi lugeleze ku-diode okuthinta ukukhiqizwa kwamandla kwezinye izingxenye ezivamile, kuyilapho futhi kuvikela izingxenye ezidlule ekuchemeni ukuya phambili okuphezulu noma ukulimala ngenxa“Umphumela wendawo eshisayo”ukushisa.

Ama-bypass diode ngokuvamile afakwa ngokuqondile ebhokisini lokuhlangana, ngokuya ngosayizi wengxenye yamandla kanye nenani lamabhethri, ukufakwa kwama-diode angu-1 ~ 3.

I-by-pass diode ayidingeki kunoma yisiphi isimo, lapho izingxenye zisetshenziswa zodwa noma ngokufana, akudingekile ukuxhuma i-diode.Ezingxenyeni ezimbalwa ochungechungeni kanye nendawo enhle yokusebenza, ungacabangela nokusetshenziswa kwama-bypass diode.
