Kwindawo yamandla avuselelekayo, iiseli zelanga ze-photovoltaic (PV) ziye zavela njengephambili, zisebenzise amandla elanga ukuvelisa umbane. Nangona kunjalo, ezi zixhobo zibuthathaka zichaphazeleka kumonakalo ovela kwimisinga ebuyayo, enokuthi yenzeke ngenxa yomthunzi okanye iimodyuli ezingahambelaniyo. Ukukhusela iiseli zelanga kunye nokuqinisekisa ukusebenza kakuhle kwenkqubo, abahlaziyi beSchottky bangena njengabakhuseli abayimfuneko. Esi sithuba sebhlog sijonga indima ebalulekileyo ye-Schottky rectifiers kwiiseli zelanga ze-photovoltaic, ukuhlola iindlela zabo zokukhusela kunye neenzuzo abazizisa kwiinkqubo zamandla elanga.
Ukuqonda uMsongelo wokuReverse Currents
Imisinga ebuyela umva ibeka isoyikiso esibalulekileyo kwiiseli zelanga, ezivela kwiimeko ezinje:
I-Shading: Xa inxalenye yepaneli yelanga ifakwe i-shaded, inokuvelisa amandla amancinci kuneeseli ezingafakwanga, ezikhokelela kumbane ojikelezayo ojikelezayo kwiseli enomthunzi.
Iimodyuli ezingahambelaniyo: Umahluko ekusebenzeni kwemodyuli okanye ukuguga kunokubangela ukungahambi kakuhle ekuveliseni amandla, okukhokelela kwimisinga ebuyela umva ehamba ngeemodyuli ezingasebenzi kakuhle.
Iimpazamo eziGround: Ukumisa okungahambi kakuhle okanye ukwaphuka kwe-insulation kunokwazisa imisinga ebuyela umva kuluhlu lwelanga, ezinokuthi zonakalise iiseli ezidityanisiweyo.
Ikhaka loKhuselo: Schottky Rectifiers
I-Schottky rectifiers isebenza njengemiqobo ekhuselayo, ikhusela imisinga enobungozi ukuba ihambe ngeeseli zelanga. Iimpawu zabo ezizodwa zibenza balungele lo msebenzi ubalulekileyo:
Ukuhla kweVoltage ePhambili ePhambili: Izihlaziyi zeSchottky zibonisa ukuhla kwamandla ombane asezantsi kakhulu xa kuthelekiswa nezihlaziyi zesilicon zemveli, ukunciphisa ilahleko yamandla kunye nokuphucula ukusebenza kakuhle kwenkqubo.
Isantya soTshintsho oluKhawuleza: Aba bahlaziyi banamandla okutshintsha ngokukhawuleza, okubavumela ukuba baphathe okukhawulezayo kwangoku okudibana nabo kwiinkqubo zePV.
Ukuvuza okuNgena phantsi okuNgenisayo kwangoku: Ukuvuza okuncinci okubuyela umva ngoku kuqinisekisa ukuchithwa kwamandla okuncinci kunye nokugcina ukusebenza kakuhle kwenkqubo.
Izibonelelo zeSchottky Rectifiers kuKhuseleko lweSolar Cell
Ukukhusela iiSeli zeSolar: Izilungisi ze-Schottky zithintela ngokufanelekileyo imisinga ebuyayo ekonakalisa iiseli zelanga, zandisa ubomi bazo kunye nokugcina ukusebenza kwenkqubo.
Ukomelezwa kweNkqubo yokuSebenza: Ngokunciphisa ilahleko yamandla ngenxa yokuhla kwamandla ombane asezantsi ngaphambili kunye nokuvuza okubuyela umva ngoku, izihlaziyi zeSchottky zinegalelo kwinkqubo yamandla elanga esebenza ngakumbi.
Ukuphucula ukuthembeka kweNkqubo: Ukukhusela iiseli zelanga ukusuka kwi-reverse currents kunciphisa umngcipheko wokungaphumeleli kunye nexesha lokuphumla, ukuqinisekisa inkqubo yamandla elanga ethembekileyo.
Ukusetyenziswa kwe-Schottky Rectifiers kwiiNkqubo zeSolar
I-Bypass Diodes: I-Schottky rectifiers isetyenziswa ngokubanzi njenge-bypass diode ukukhusela iiseli zelanga ezizimeleyo ezibangelwa kumthunzi okanye ukungaphumeleli kwemodyuli.
I-Freewheeling Diode: Kwi-DC-DC converters, i-Schottky rectifiers isebenza njenge-freewheeling diode ukukhusela i-inductor kickback kunye nokuphucula ukusebenza kakuhle kwesiguquli.
Ukhuseleko lokutshaja ibhetri: Izilungisi ze-Schottky zikhusela iibhetri ukusuka kwimisinga ebuyayo ngexesha lokutshaja.
Iziguquli zeSola: Izilungisi zeSchottky zisetyenziswa kwiziguquli zelanga ukulungisa imveliso ye-DC ukusuka kuluhlu lwelanga ukuya kumandla e-AC kuqhagamshelo lwegridi.
Ukuqukumbela: Abakhuseli abayimfuneko kwiSolar Realm
I-Schottky rectifiers ziye zazimisela ngokwazo njengamacandelo abalulekileyo kwiinkqubo zelanga ze-photovoltaic (PV), ezibonelela ngokhuseleko oluqinileyo kwimiphumo eyingozi ye-reverse currents. Ukuhla kwabo kwamandla ombane asezantsi, isantya sokutshintsha ngokukhawuleza, ukuvuza okusezantsi okubuyela umva ngoku, ubungakanani obubambeneyo, kunye nokusebenza kakuhle kweendleko kubenza babe lolona khetho lukhethwayo lokukhusela iiseli zelanga kunye nokuphucula ukusebenza kakuhle kwenkqubo. Njengoko imfuno yamandla ahlaziyekayo iqhubeka nokunyuka, abahlaziyi beSchottky bakulungele ukudlala indima ebaluleke kakhulu ekukhuseleni ukusebenza kunye nokuthembeka kweenkqubo zamandla elanga, ukunika amandla ikamva elizinzileyo.
