Ukubaluleka kwee-photovoltaic diodes ekuveliseni amandla elanga

Kwi-square array yeseli yelanga, i-diode sisixhobo esixhaphake kakhulu, i-diode esetyenziswa ngokuqhelekileyo yi-silicon rectifier diode, ekukhethweni kweenkcukacha zokugcina iiparitha, ukukhusela umonakalo wokuphuka.Ngokuqhelekileyo, i-voltage ye-reverse peak breakdown kunye neyona ndlela yokusebenza ephezulu kufuneka ibe ngaphezu kwamaxesha ama-2 ombane osebenzayo kunye nokusebenza ngoku.Kukho iintlobo ezimbini eziphambili zediode kwiinkqubo ze-photovoltaics.

I-Diode yokuthintela ukutshaja umva (ukuthintela umva ngoku)

Omnye wemisebenzi yeDiode yokuthintela ukutshaja umva (ukuthintela ukutshaja umva) kukuthintela umbane weseli yelanga ukuba uguqulwe kwiseli yelanga okanye i-square array xa iseli yelanga okanye i-square array ingavelisi umbane. Indima ikuluhlu lwebhetri, ukuthintela okwangoku phakathi kwamasebe oluhlu olubuyiselwe umva.Oku kungenxa yokuba amandla ombane aphumayo kwisebe ngalinye kuthotho akakwazi ukulingana ngokupheleleyo, kusoloko kukho umahluko phakathi kwamandla ombane aphezulu naphantsi kwisebe ngalinye, okanye amandla ombane aphumayo esebe athotywa ngenxa yempazamo yesebe elinye, ukuthungatha. , njl. njlLe nto inokuphetshwa ngokudibanisa i-anti-back-filling diodes kwichungechunge kwisebe ngalinye.

Slocable'sI-Anti-Reverse Diodeinomthamo olinganiselweyo we-1600V, amandla ombane wokuhlukanisa umbane ukuya kuthi ga kwi-3100V phakathi kwetshiphu kunye ne-substrate, i-glass passivated chip soldered, iimpawu zobushushu ezibalaseleyo kunye namandla okuhamba ngebhayisikile, kunye ne-silicon carbide diode, kunosetyenziso lwamandla lwe-diode oluqhelekileyo olungaphezulu kwe-15. % .Ilinganiswe ngoku ukuya kwi-55 A. Ukuba inkqubo yakho inomlinganiselo wangoku ongaphezu kwe-12A, le diode iyacetyiswa ukukhusela amacandelo akho.

I-Bypass diode

Xa iimodyuli ezininzi zeeseli zelanga ziqhagamshelwe kuthotho ukwenza isebe loluhlu lweeseli okanye uluhlu lweeseli, enye (okanye ezimbini okanye ezintathu) iidiode kufuneka zidityaniswe ngokuhambelana ngokulandelelanayo kwitheminali elungileyo nengalunganga yephaneli nganye, le diode. , edityaniswe ngokufanayo kuzo zombini iziphelo zeNdibano, ibizwa ngokuba yi-bypass diode.

Indima ye-bypass diodes kukuthintela icandelo okanye inxalenye yecandelo kuluhlu lwesikwere ukuba libe nomthunzi okanye ukumiswa kwimveliso yamandla xa kukho ukusilela, uthotho lwangoku lwamacandelo ludlula amacandelo angalunganga kwaye luqukuqele kwidiode ngaphandle kokusilela. ichaphazela ukuveliswa kwamandla kwamanye amacandelo aqhelekileyo, ngeli lixa ikwakhusela amacandelo ekugqithwa kuwo ukusuka kumkhethe ophambili okanye umonakalo ngenxa“Isiphumo sendawo eshushu”ukufudumeza.

I-Bypass diodes ifakwe ngokubanzi ngokuthe ngqo kwibhokisi ye-junction, ngokobukhulu becandelo lamandla kunye nenani leebhetri, ukufakwa kwe-1 ~ 3 diode.

I-diode yokudlula ayifuni nakweyiphi na imeko, xa amacandelo asetyenziswa yedwa okanye ngokufanayo, akuyimfuneko ukudibanisa i-diode.Kumacandelo ambalwa kuthotho kunye nendawo elungileyo yokusebenza, unokuqwalasela kwakhona ukusetyenziswa kweediode ze-bypass.
