Pamalo a mphamvu zongowonjezereka, ma cell a solar a photovoltaic (PV) atuluka ngati otsogola, akugwiritsa ntchito mphamvu ya dzuwa kupanga magetsi. Komabe, zida zolimba izi zimatha kuwonongeka chifukwa cha mafunde obwerera kumbuyo, omwe amatha kuchitika chifukwa cha shading kapena ma module osagwirizana. Kuti muteteze ma cell a solar ndikuwonetsetsa kuti machitidwe akuyenda bwino, okonzanso a Schottky amalowamo ngati oteteza ofunikira. Cholemba chabuloguchi chikuwunikiranso za ntchito yofunika kwambiri ya Schottky rectifiers mu cell solar photovoltaic, ndikuwunika njira zawo zodzitetezera komanso mapindu omwe amabweretsa kumagetsi adzuwa.
Kumvetsetsa Chiwopsezo cha Reverse Currents
Mafunde obwerera kumbuyo amawopseza kwambiri ma cell a solar, omwe amayamba chifukwa cha zinthu monga:
Shading: Gawo la solar likakhala ndi mthunzi, limatha kupanga mphamvu zochepa kuposa ma cell osasunthika, zomwe zimapangitsa kuti mafunde obwerera m'mbuyo akuyenda mu cell yamthunzi.
Ma module Osafananirana: Kusiyanasiyana kwa magwiridwe antchito kapena ukalamba kungayambitse kusagwirizana pakupanga mphamvu, zomwe zimapangitsa kuti mafunde obwerera m'mbuyo aziyenda kudzera m'ma module osagwira ntchito.
Zowonongeka Pansi: Kuyika kolakwika kwa nthaka kapena kutsekeka kungathe kuyambitsa mafunde ozungulira munjira ya solar, zomwe zitha kuwononga ma cell olumikizidwa.
Chitetezo Choteteza: Schottky Rectifiers
Schottky rectifiers amachita ngati zotchinga zoteteza, kuteteza mafunde oyipa kuti asadutse ma cell adzuwa. Makhalidwe awo apadera amawapangitsa kukhala abwino pantchito yovutayi:
Low Forward Voltage Drop: Schottky rectifiers amawonetsa kutsika kotsika kwambiri kwa voliyumu yakutsogolo poyerekeza ndi zokonzanso zachikhalidwe za silicon, kuchepetsa kutayika kwa mphamvu ndikuwonjezera mphamvu zamakina.
Kuthamanga Kwachangu: Okonzansowa ali ndi kuthekera kosintha mwachangu, kuwapangitsa kuti athe kuthana ndi zosintha zomwe zikuchitika mu makina a PV.
Low Reverse Leakage Current: Kutsika pang'ono kwapang'onopang'ono kumapangitsa kuti mphamvu iwonongeke pang'ono ndikusunga magwiridwe antchito onse.
Ubwino wa Schottky Rectifiers mu Solar Cell Protection
Kuteteza Maselo a Dzuwa: Schottky rectifiers amateteza bwino mafunde obwerera kumbuyo kuti asawononge ma cell adzuwa, kumatalikitsa moyo wawo ndikusunga magwiridwe antchito.
Kukhathamiritsa Kwadongosolo Kwadongosolo: Pochepetsa kutayika kwa magetsi chifukwa cha kutsika kwamagetsi akutsogolo komanso kutsika kwaposachedwa, Schottky rectifiers amathandizira kuti pakhale mphamvu yoyendera dzuwa.
Kudalirika Kwadongosolo Kwadongosolo: Kuteteza ma cell a solar ku mafunde obwerera kumbuyo kumachepetsa chiopsezo cha kulephera ndi kutsika, kuonetsetsa kuti mphamvu ya dzuwa idali yodalirika.
Kugwiritsa ntchito kwa Schottky Rectifiers mu Solar Systems
Bypass Diode: Schottky rectifiers amagwiritsidwa ntchito kwambiri ngati ma bypass diode kuti ateteze ma cell a solar pawokha ku mafunde obwerera kumbuyo chifukwa cha kulephera kwa shading kapena ma module.
Ma diode a Freewheeling: Mu ma converter a DC-DC, ma Schottky rectifiers amagwira ntchito ngati ma diode aulere kuti apewe kubweza kwa inductor komanso kupititsa patsogolo luso losinthira.
Kuteteza Battery Charging: Schottky rectifiers amateteza mabatire ku mafunde obwerera kumbuyo panthawi yolipiritsa.
Ma Solar Inverters: Ma Schottky rectifiers amagwiritsidwa ntchito mu ma inverter a solar kuti akonzenso kutulutsa kwa DC kuchokera pagulu la solar kukhala mphamvu ya AC yolumikizira grid.
Kutsiliza: Oteteza Ofunika Kwambiri mu Dziko la Solar
Schottky rectifiers adzipanga okha ngati zigawo zofunika kwambiri mu solar system photovoltaic (PV), kupereka chitetezo champhamvu ku zotsatira zowononga za mafunde obwerera. Kutsika kwawo kwamagetsi otsika, kuthamanga kwachangu, kutsika kwapang'onopang'ono, kukula kwapang'onopang'ono, komanso kukwera mtengo kwake kumawapangitsa kukhala chisankho chomwe amakonda kuteteza ma cell a solar ndikupititsa patsogolo magwiridwe antchito. Pomwe kufunikira kwa mphamvu zongowonjezedwanso kukukulirakulira, okonzanso a Schottky ali okonzeka kutenga gawo lofunikira kwambiri pakuteteza magwiridwe antchito ndi kudalirika kwamagetsi amagetsi adzuwa, ndikupangitsa tsogolo lokhazikika.
