I-inverter yingqondo kunye nentliziyo yenkqubo yokuvelisa amandla e-photovoltaic.Kwinkqubo ye-solar photovoltaic power generation, amandla aveliswa yi-photovoltaic array yi-DC amandla.Nangona kunjalo, imithwalo emininzi ifuna amandla e-AC, kwaye inkqubo yonikezelo lwamandla yeDC inemida enkulu kwaye ayilunganga ukuguqula umbane., Uluhlu lwesicelo somthwalo lukhawulelwe, ngaphandle komthwalo okhethekileyo wamandla, ii-inverters ziyafuneka ukuguqula amandla e-DC kumandla e-AC.I-photovoltaic inverter yintliziyo yenkqubo yokuvelisa amandla elanga ye-photovoltaic, eguqula i-current ngqo eyenziwa yimodyuli ye-photovoltaic kwi-alternating current, kwaye idlulisele kumthwalo wendawo okanye igridi, kwaye i-electronic device enamandla kunye nemisebenzi ehambelanayo yokukhusela.
I-inverter yelanga iqulethwe kakhulu iimodyuli zamandla, iibhodi zeesekethe zokulawula, i-breakers circuit, izihlungi, i-reactors, i-transformers, i-contactors kunye neekhabhinethi.Inkqubo yokuvelisa ibandakanya iinxalenye ze-electronic pre-processing, indibano epheleleyo yomatshini, uvavanyo kunye nokupakishwa komatshini.Uphuhliso lwayo luxhomekeke kuphuhliso lobuchwepheshe be-elektroniki yamandla, itekhnoloji yesixhobo se-semiconductor kunye neteknoloji yolawulo lwangoku.
Kwii-inverters zelanga, ukuphucula ukuguqulwa kokusebenza kombane kuyisihloko esingunaphakade, kodwa xa ukusebenza kakuhle kwenkqubo kuphakama nangaphezulu, phantse kusondele kwi-100%, ukuphuculwa okuqhubekayo kokusebenza kuya kuhamba kunye nokusebenza kweendleko eziphantsi.Ngoko ke, indlela yokugcina Ukusebenza okuphezulu, kodwa kunye nokugcina ukukhuphisana kwexabiso elihle kuya kuba sisihloko esibalulekileyo ngoku.
Xa kuthelekiswa neenzame zokuphucula ukusebenza kakuhle kwe-inverter, indlela yokuphucula ukusebenza kakuhle kwenkqubo yonke ye-inverter ngokuthe ngcembe ibe yinto ebalulekileyo kwiinkqubo zamandla elanga.Kuluhlu lwelanga, xa indawo ye-2% -3% yendawo yesithunzi ibonakala, kwi-inverter esebenzisa umsebenzi weMPPT, amandla emveliso yenkqubo ngeli xesha anokwehla malunga ne-20% xa amandla okuphuma engalunganga. .Ukuze ulungelelanise ngcono imeko efana nale, yindlela esebenzayo kakhulu yokusebenzisa i-MPPT enye okanye enye imisebenzi yokulawula i-MPPT kwiimodyuli zelanga enye okanye inxalenye.
Ekubeni inkqubo ye-inverter ikwimeko yokusebenza kwegridi edibeneyo, ukuvuza kwenkqubo emhlabeni kuya kubangela iingxaki ezinzulu zokhuseleko;ukongeza, ukuze kuphuculwe ukusebenza kakuhle kwenkqubo, uninzi lwezixhobo zelanga ziya kudityaniswa kuthotho ukwenza i-voltage ephezulu ye-DC;Ngenxa yokwenzeka kweemeko ezingaqhelekanga phakathi kwee-electrodes, kulula ukuvelisa i-DC arc.Ngenxa yombane ophezulu we-DC, kunzima kakhulu ukucima i-arc, kwaye kulula kakhulu ukubangela umlilo.Ngokwamkelwa ngokubanzi kweenkqubo ze-inverter zelanga, umba wokhuseleko lwenkqubo uya kuba yinxalenye ebalulekileyo yetekhnoloji ye-inverter.
