I-Inverter, eyaziwa ngokuba ngumlawuli wamandla, umlawuli wamandla, uyinxalenye ebalulekileyo yenkqubo ye-photovoltaic.Umsebenzi obaluleke kakhulu we-photovoltaic inverter kukuguqula amandla e-DC aveliswa yipaneli yelanga kumandla e-AC asetyenziswa zixhobo zasekhaya.Wonke umbane oveliswa yipaneli yelanga unokuthunyelwa kumazwe angaphandle ngonyango lwe-inverter.through-full-bridge circuit, ngokuqhelekileyo ithatha iprosesa ye-SPWM ngokumodareyitha, ukucoca, ukunyuswa kwamandla ombane, njl., Ukufumana inkqubo ye-AC ye-sinusoidal ehambelana nokukhanya. umthamo wokulayisha, umbane olinganisiweyo kubasebenzisi bokugqibela.Nge-inverter, ibhetri ye-DC ingasetyenziselwa ukubonelela ngamandla e-AC kwisixhobo.

Inkqubo yokuvelisa amandla eSolar AC iqukethe iipaneli zelanga, isilawuli sokutshaja, i-inverter kunye nebhetri;Inkqubo yokuvelisa amandla elanga ye-DC ayibandakanyi i-inverter.Inkqubo yokuguqula amandla ombane e-AC kumandla ombane e-DC kuthiwa lulungiso, umjikelo ogqibezela umsebenzi wokulungisa ubizwa ngokuba yi-rectifier circuit, kunye nesixhobo esiqonda inkqubo yolungiso. eyaziwa njengesixhobo sokulungisa okanye isilungisi. Ngokuhambelanayo, inkqubo yokuguqula amandla ombane e-DC kumandla ombane e-AC kuthiwa yi-inverter, isekethe egqibezela umsebenzi wokuguqula ibizwa ngokuba yi-inverter circuit, kunye nesixhobo esiqonda inkqubo yoguqulo. ibizwa ngokuba sisixhobo sokuguqula izinto okanye isiguquli.
Undoqo wesixhobo se-inverter yisekethe yokutshintsha i-inverter, ngokulula i-inverter circuit.Isekethe igqibezela umsebenzi wokuguqula ngokuvula kunye nokucima umbane we-electronic switch.Ukucinywa kwamandla okutshintsha kwezixhobo zombane kufuna ii-pulses ezithile zokuqhuba, ezinokuthi ilawulwa ngokutshintsha isignali ye-voltage.Iijikelezo ezivelisa kunye nokulawula i-pulses zibizwa ngokuqhelekileyo ngokuba yi-control circuit okanye i-control circuit.Isakhiwo esisisiseko se-inverter device, ngaphezu kwe-inverter circuit ekhankanywe ngasentla kunye nesekethe yokulawula, nayo inayo isekethe yokukhusela, isiphaluka semveliso, isiphaluka semveliso, isiphaluka semveliso kunye nokunye.

I-inverter esembindini isetyenziswa ngokubanzi kwiinkqubo ezinezikhululo zamandla ephotovoltaic ezinkulu (> 10kW).Amaqela amaninzi e-photovoltaic ahambelanayo axhunyiwe kwigalelo le-DC ye-inverter efanayo ephakathi.Ngokuqhelekileyo, amandla amakhulu asebenzisa imodyuli yamandla e-IGBT yesigaba sesithathu, amandla amancinci asebenzisa i-transistors ye-field effect, kwaye asebenzise isilawuli sokuguqulwa kwe-DSP ukuphucula umgangatho wamandla ombane wokuphuma kombane, okwenza ukuba usondele kakhulu kwi-sinusoidal wave current.Eyona nto inkulu yinto ephakamileyo ephezulu. amandla kunye neendleko eziphantsi.Nangona kunjalo, ngenxa yokulinganisa uchungechunge lweqela le-photovoltaic kunye ne-shading inxalenye, kukhokelela ekusebenzeni kakuhle kunye namandla ombane wenkqubo yonke ye-photovoltaic.Ngexesha elifanayo, ukuthembeka kokuveliswa kwamandla kwenkqubo yonke ye-photovoltaic ukuchatshazelwa yimeko engasebenzi kakuhle yeqela elithile leyunithi ye-photovoltaic.Ulwalathiso lophando lwamva nje lulawulo lokumodareyitha kwee-vectors zendawo, kunye nokuphuhliswa koxhumo lwe-topological of inverters entsha ukuze kufumaneke ukusebenza okuphezulu kwiimeko zomthwalo wecala.Kwi-SolarMax (i-SolarMax) I-SowMac) inverter esembindini, ibhokisi yojongano lwe-photovoltaic array inokongezwa ukujonga uthotho ngalunye lwe-photovoltaic panel series.Ukuba iseti yazo ayisebenzi kakuhle, inkqubo iya kudlulisela ulwazi kwisilawuli esikude, kwaye inokumisa uthotho ngokulawula okude, ukuze kungabangela ukusilela ukunciphisa nokuchaphazela umsebenzi kunye nemveliso yamandla yonke. inkqubo ye-photovoltaic.
