Utugenzura cyangwa utugenzura imirasire y'izuba ni ibikoresho bikoreshwa mu matara akoresha imirasire y'izuba kugira ngo bigenzure umuyoboro w'amashanyarazi uva kuri panel y'izuba ujya kuri bateri. Utugenzura imirasire y'izuba na two dufite inshingano zo kugabanya umuyoboro uva kuri bateri ujya kuri LED. Muri sisitemu y'amatara y'izuba, utugenzura bigira uruhare runini mu gucunga umuyoboro n'amashanyarazi. Iyo panel z'izuba zihagaritse gutanga ingufu izuba rirenze, utugenzura dufasha guhindura LED.
Hari amahirwe ko amashanyarazi ashobora gutembera inyuma ava kuri bateri ajya kuri paneli iyo nta muyoboro w'amashanyarazi ukorwa nijoro, ibyo bikaba byakwangiza ubuzima bwa bateri. Imashini zigenzura umuriro zifasha mu gukumira ubu buryo bwo gusubira inyuma bw'amashanyarazi zimenya igihe nta muyoboro w'amashanyarazi uhari no gukuraho paneli zigenzura umuriro kuri bateri kugira ngo hirindwe ko ziyongera. Gushyira umuriro mwinshi bishobora kandi kugabanya igihe bateri zimara kandi imashini zigenzura umuriro zigezweho zifasha mu kongera igihe bateri imara mu kugabanya ingano y'umuriro ukoreshwa kuri bateri iyo yuzuye umuriro kandi bikanafasha mu guhindura voltage irenze umuyoboro w'amashanyarazi mo amperage.
Kuki ibikoresho bigenzura imirasire y'izuba bikenerwa mu matara akoresha imirasire y'izuba?
●Kugenzura ingufu z'amashanyarazi za bateri
●Kugira ngo hirindwe ko umugezi usubira inyuma
●Kwirinda gusharija cyane cyangwa gusharija bateri nkeya
●Kugaragaza igihe bateri ishaje
Ubwoko bw'ibikoresho bigenzura amashanyarazi akomoka ku mirasire y'izuba
Ibyuma bigenzura ubwinshi bw'amajwi (PWM)
PWM niyo controller ikoreshwa cyane kuko ikoresha ikoranabuhanga ryamaze igihe kinini rikoreshwa mu kugenzura urujya n'uruza rw'amashanyarazi. Ihindagurika ry'ubugari bw'umuvuduko w'amashanyarazi ribaho iyo bateri igeze ku rwego rwo gusharija rungana binyuze mu kugabanya umuvuduko w'amashanyarazi buhoro buhoro. Kwiyatsa umuriro ni ikibazo gikunze kugaragara muri bateri nyinshi zishobora kongera gusharija aho zikunze kubura ingufu iyo zimaze gusharija yuzuye. Controller ya PWM irakomeza gutanga ingufu nke buri gihe kugira ngo bateri ikomeze gusharija yuzuye kandi ikomeze gusharija, bityo ikirinda kwiyatsa umuriro.
Utwuma dupima PWM dufatwa nk'udukomeye cyane kandi dukora neza mu bihe bishyushye. Duhenze cyane kandi tuboneka mu bunini butandukanye mu bikorwa bitandukanye. Hamwe n'utwuma dupima PWM, ni ngombwa kugira panels z'izuba na bateri zifite voltage zihuye. PWM charge controller ni ubwoko busanzwe bwo kugenzura charger bukoreshwa mu matara yo ku muhanda akoresha imirasire y'izuba kandi bukwiriye cyane no ku tunyabutabire duto tw'izuba dufite panels nto na bateri.
Ibikoresho bigenzura amashanyarazi byihuta cyane (MPPT)
Udukoresho twa MPPT dutwara amashanyarazi ni amahitamo ahenze kandi agoye kuri sisitemu z'izuba; icyakora, kimwe mu byiza bikomeye by'izi mashini zitwara amashanyarazi ni uko bitandukanye na PWM, utwo dukoresho twa MPPT dushobora guhuza voltage zidahuye n'izuba na bateri. Ubuhanga bukoreshwa muri MPPT ni bushya butuma utwo dukoresho dukora ku ngufu ntarengwa. Kubera ingano itandukanye y'imirasire y'izuba umunsi wose, voltage y'izuba n'umuvuduko w'amashanyarazi bishobora gutandukana. Udukoresho twa MPPT duhindura voltage kugira ngo tubone ingufu ntarengwa uko ikirere cyaba kiri kose.
Abagenzuzi ba MPPT bashyushya vuba kandi bamara igihe kirekire. Bashobora guhindura uburyo bakoresha kugira ngo batangire ingufu nyinshi zishoboka ziturutse kuri paneli. Aba bagenzuzi barashobora guhindura imbaraga zisohoka kugira ngo zihuze n'imbaraga za bateri. Bagaragara ko bakora neza mu bihe bikonje kandi bafatwa nk'abakora neza kurusha abagenzuzi ba PWM.
Ni gute wahitamo icyuma gipima umuriro gikwiye?
Utwuma twombi twa PWM ndetse na MPPT dukoreshwa mu matara yo ku muhanda akoresha imirasire y'izuba. Utwuma twombi dukora nk'igikoresho cyo kurinda kandi tugakuramo ibyiza mu cyuma cyawe cy'izuba. Ukurikije ibi bikurikira, ugomba guhitamo icyuma gikoresha imirasire y'izuba gihuye n'amashanyarazi ya sisitemu yawe.
Igihe cyose cy'ubugenzuzi
Aho byashyizwe n'ubushyuhe bwabyo
Ibisabwa mu bijyanye n'ingufu n'ingengo y'imari
Ingufu z'izuba
Ingano rusange y'urumuri rw'izuba
Ubwoko bwa bateri ikoreshwa mu rumuri rw'izuba
Nkuko bigaragara ku ifoto, Zenith Lighting ni uruganda rw'umwuga rukora amatara yo ku muhanda y'ubwoko bwose, niba ufite ikibazo cyangwa umushinga, nyamuneka ntutindiganye kutuvugisha.
