Emkhakheni wamandla avuselelekayo, amangqamuzana elanga e-photovoltaic (PV) aqhamuke njengangaphambili, esebenzisa amandla elanga ukuze akhiqize ugesi. Kodwa-ke, lawa madivayisi athambile asengozini yokulimala kusuka kumaza abuyela emuva, okungenzeka ngenxa yokufiphaza noma amamojula angafani. Ukuze kuvikelwe amaseli elanga nokuqinisekisa ukusebenza kahle kwesistimu, izilungisi ze-Schottky ziyangena njengezivikeli ezibalulekile. Lokhu okuthunyelwe kwebhulogi kucubungula indima ebalulekile ye-Schottky rectifiers kumaseli elanga e-photovoltaic, ihlola izindlela zabo zokuzivikela kanye nezinzuzo ezizilethayo ezinhlelweni zamandla elanga.
Ukuqonda Usongo Lwama-Reverse Currents
Imisinga ehlehlayo ibeka usongo olukhulu kumaseli elanga, avela ezimweni ezifana nalezi:
I-Shading: Uma ingxenye yephaneli yelanga ifakwe umthunzi, ingakwazi ukukhiqiza amandla amancane kunamaseli angafakwanga umthunzi, okuholela emisinga ehlehlayo egeleza kuseli elinomthunzi.
Amamojula Angafani: Umehluko ekusebenzeni kwemojuli noma ukuguga kungabangela ukungafani ekukhiqizeni amandla, okuholela ekutheni ama-currents ahlehlayo ageleze ngamamojula asebenza kancane.
Amaphutha Aphansi: Ukubekwa phansi okunephutha noma ukwehlukana kwe-insulation kungangenisa amaza ahlehlayo kuhlelo lwelanga, okungase kulimaze amaseli axhunyiwe.
I-Protective Shield: I-Schottky Rectifiers
Ama-rectifiers e-Schottky asebenza njengezithiyo ezivikelayo, ezivimbela amaza ayingozi ahlehlayo ukuthi angagelezi kumaseli elanga. Izici zabo ezihlukile zibenza balungele lo msebenzi obalulekile:
I-Low Forward Voltage Drop: Izilungisi ze-Schottky zibonisa ukwehla kwamandla kagesi aya phambili okuphansi kakhulu uma kuqhathaniswa nezilungisi ze-silicon ezivamile, ezinciphisa ukulahleka kwamandla nokuthuthukisa ukusebenza kahle kwesistimu.
Isivinini Sokushintsha Okusheshayo: Lezi zilungisi zinamandla okushintsha ngokushesha, okuzivumela ukuthi zikwazi ukuphatha izinto ezidlulayo ezisheshayo ezitholwe kumasistimu e-PV.
Ukuvuza Okuhlehla Okuphansi Kwamanje: Ukuvuza okuhlanekezela okuphansi kwamanje kuqinisekisa ukuchithwa kwamandla okuncane futhi kugcina ukusebenza kahle kohlelo lonke.
Izinzuzo ze-Schottky Rectifiers ekuvikelweni kwamaseli eSolar
Ukuvikela Amangqamuzana Elanga: Izilungisi ze-Schottky zivimbela ngempumelelo ama-currents abuyela emuva emonakalweni wamaseli elanga, andise ubude bazo bempilo kanye nokulondoloza ukusebenza kwesistimu.
Ukusebenza Kwesistimu Okuthuthukisiwe: Ngokunciphisa ukulahleka kwamandla ngenxa yokwehla kwe-voltage eya phambili ephansi nokuvuza kwamanje, izihlungi ze-Schottky zifaka isandla kusistimu yamandla elanga esebenza kahle kakhulu.
Ukuthembeka Kwesistimu Okuthuthukisiwe: Ukuvikela amangqamuzana elanga emisinga ehlehlayo kunciphisa ubungozi bokuhluleka kanye nesikhathi sokuphumula, kuqinisekisa uhlelo lwamandla elanga oluthembeke kakhulu.
Izicelo ze-Schottky Rectifiers ku-Solar Systems
Ama-Bypass Diode: Izihlungi ze-Schottky zisetshenziswa kabanzi njengama-bypass diode ukuze kuvikelwe amaseli elanga angawodwana kumaza abuyela emuva abangelwa ukufiphala kwe-shading noma amamojula.
Ama-Freewheeling Diode: Kuziguquli ze-DC-DC, izihlungi ze-Schottky zisebenza njengama-freewheeling diode ukuvimbela i-inductor kickback futhi kuthuthukise ukusebenza kahle kwesiguquli.
Ukuvikela Ukushaja Ibhethri: Izilungisi ze-Schottky zivikela amabhethri kusuka kumaza abuyela emuva phakathi nemijikelezo yokushaja.
Iziguquli Zelanga: Izilungisi ze-Schottky zisetshenziswa kuziguquli zelanga ukuze kulungiswe ukuphuma kwe-DC kusuka kuhlelo lwelanga kuya kumandla e-AC okuxhumana kwegridi.
Isiphetho: Abavikeli Ababalulekile endaweni yeSolar
I-Schottky rectifiers izenzele njengezingxenye ezibalulekile kumasistimu elanga e-photovoltaic (PV), ehlinzeka ngokuzivikela okuqinile emiphumeleni eyingozi yemisinga ehlehlayo. Ukwehla kwamandla kagesi aya phambili aphansi, isivinini sokushintsha ngokushesha, ukuvuza okuhlanekezela okuphansi kwamanje, usayizi ohlangene, kanye nokusebenza kahle kwezindleko kuwenza abe yinketho ekhethwayo yokuvikela amaseli elanga nokuthuthukisa ukusebenza kahle kwesistimu. Njengoba isidingo samandla avuselelekayo siqhubeka nokwanda, izilungisi ze-Schottky zikulungele ukudlala indima ebaluleke kakhulu ekuvikeleni ukusebenza nokuthembeka kwezinhlelo zamandla elanga, ukunika amandla ikusasa elisimeme.
