Akamaro ka diode ya Photovoltaque mukubyara izuba

Muburyo bwa kare ya selile yizuba, diode nigikoresho gisanzwe cyane, diode ikoreshwa cyane ni silicon rectifier diode, muguhitamo ibisobanuro kugirango ubike ibipimo, kugirango wirinde kwangirika.Mubisanzwe, rever ya peak breakdown voltage hamwe nigikorwa kinini cyo gukora kigomba kuba kirenze inshuro 2 za voltage nini nini ikora.Hariho ubwoko bubiri bwingenzi bwa diode muri sisitemu yo gufotora.

Diode yo gukumira kwishyuza kwinyuma (gukumira imiyoboro ihindagurika)

Imwe mumikorere ya Diode mukurinda gukumira kwishyurwa kwinyuma (kubuza kwishyuza inyuma) nukwirinda ko ingirabuzimafatizo yizuba idasubira mumirasire yizuba cyangwa umurongo wa kare mugihe ingirabuzimafatizo yizuba cyangwa umurongo wa kare utabyara amashanyarazi Iya kabiri Uruhare ruri muri bateri yumurongo, kugirango wirinde ikigezweho hagati yamashami yikurikiranya.Ibi ni ukubera ko ibisohoka biva muri buri shami murukurikirane bidashobora kuba bingana rwose, burigihe hariho itandukaniro hagati yumuvuduko mwinshi kandi muto wa buri shami, cyangwa ingufu ziva mumashami ziramanuka kubera amakosa yishami rimwe, igicucu , etc.Iyi phenomenon irashobora kwirindwa muguhuza anti-back-kuzuza diode murukurikirane muri buri shami.

Kwimuka'sKurwanya Diodeifite voltage yagereranijwe ya 1600V, amashanyarazi y’amashanyarazi agera kuri 3100V hagati ya chip na substrate, chip passivated chip yagurishijwe, ibiranga ubushyuhe buhebuje nubushobozi bwo gusiganwa ku magare, hamwe na diode ya karubide ya silicon, kuruta gukoresha ingufu za diode zisanzwe zikoresha 15 zirenga 15 %.Ikigereranyo kigezweho kugeza kuri 55 A. Niba sisitemu yawe ifite igipimo kirenze 12A, iyi diode irasabwa kurinda ibice byawe.

Bypass diode

Iyo imirasire y'izuba myinshi ihujwe mukurikirane kugirango igire ishami ryingirabuzimafatizo cyangwa selile, selile imwe (cyangwa ebyiri cyangwa eshatu) igomba guhuzwa muburyo bubangikanye nibintu byiza kandi bibi biva muri buri panel, iyi diode , ihujwe mu buryo bubangikanye ku mpande zombi z'Inteko, yitwa diode ya bypass.

Uruhare rwa byode ya diode ni ukurinda igice cyangwa igice cyibigize murwego rwa kare umurongo utagira igicucu cyangwa ugahagarikwa kubyara amashanyarazi mugihe habaye kunanirwa, urukurikirane rwibintu bigize ibice bikuraho ibice bitari byiza kandi bikanyura muri diode nta bigira ingaruka kumashanyarazi yibindi bice bisanzwe, mugihe nanone irinda ibice byambukiranya kubogama hejuru cyangwa kwangirika bitewe“Ingaruka ishyushye”gushyushya.

Bypass diode isanzwe ishyirwaho muburyo butaziguye mu gasanduku gahuza, ukurikije ingano yimbaraga zigizwe numubare wa bateri, kwishyiriraho diode 1 ~ 3.

By-pass ya diode ntabwo isabwa mubihe byose, mugihe ibice bikoreshwa byonyine cyangwa muburyo bubangikanye, ntabwo ari ngombwa guhuza diode.Kubice bike murukurikirane hamwe nibikorwa byiza bikora, urashobora kandi gutekereza kumikoreshereze ya diode ya bypass.
