Inverter, wanda kuma aka sani da mai sarrafa wutar lantarki da mai sarrafa wutar lantarki, wani yanki ne mai mahimmanci na tsarin hotovoltaic.Babban aikin inverter na photovoltaic shine don canza halin yanzu kai tsaye ta hanyar hasken rana zuwa yanayin da ake amfani da shi ta kayan aikin gida.Ta hanyar da'irar cikakken gada, ana amfani da na'ura na SPWM gabaɗaya don daidaitawa, tacewa, haɓakawa, da sauransu, don samun wutar lantarki ta sinusoidal AC wacce ta dace da mitar nauyin haske, ƙimar ƙarfin lantarki, da sauransu don ƙarshen mai amfani da tsarin.Tare da inverter, ana iya amfani da baturin DC don samar da wutar AC ga na'urar.
Tsarin samar da wutar lantarki na AC na hasken rana yana kunshe da bangarorin hasken rana, masu kula da caji, inverters da batura;tsarin samar da wutar lantarki na hasken rana DC ba ya haɗa da inverters.Hanyar canza wutar AC zuwa wutar DC ita ake kira gyarawa, da’ira da ke kammala aikin gyaran ita ake kira da’ira mai gyarawa, ita kuma na’urar da ta gane tsarin gyara ana kiranta da na’urar gyara ko gyara.Hakazalika, tsarin juya wutar lantarkin DC zuwa AC shine ake kira inverter, da kewayen da ke kammala aikin inverter ana kiranta inverter circuit, kuma na'urar da ta gane tsarin inverter ana kiranta inverter equipment ko inverter.
Jigon na'urar inverter shine inverter switch circuit, wanda ake kira da'irar inverter a takaice.Da'irar tana kammala aikin inverter ta hanyar kunnawa da kashe wutar lantarki.Kashewar na'urori masu sauya wutar lantarki na buƙatar wasu ƙwanƙwasa tuƙi, kuma ana iya daidaita waɗannan bugunan ta canza siginar wutar lantarki.Matsalolin da ke haifarwa da yanayin bugun jini ana kiransu da'irori masu sarrafawa ko madaukai masu sarrafawa.Asalin tsarin na'urar inverter ya haɗa da na'ura mai kariya, da'irar fitarwa, da'irar shigarwa, da'irar fitarwa, da makamantansu baya ga na'urar inverter da aka ambata a sama.
Mai jujjuyawar ba wai kawai yana da aikin jujjuyawar DC-AC ba, har ma yana da aikin haɓaka aikin tantanin halitta da aikin kariyar gazawar tsarin.A taƙaice, akwai aiki ta atomatik da aikin kashewa, matsakaicin aikin sarrafa ikon sa ido, aikin anti-mai zaman kanta (don tsarin haɗin grid), aikin daidaita wutar lantarki ta atomatik (don tsarin haɗin grid), aikin gano DC (don haɗin grid). tsarin), Ayyukan gano ƙasa na DC (don tsarin haɗin grid).Anan akwai taƙaitacciyar gabatarwa ga aiki ta atomatik da ayyukan kashewa da matsakaicin aikin sarrafa wutar lantarki.
1. Aiki ta atomatik da aikin rufewa: Bayan fitowar rana da safe, ƙarfin hasken rana yana ƙaruwa a hankali, kuma fitowar tantanin rana shima yana ƙaruwa.Lokacin da ƙarfin fitarwa da ake buƙata na aikin inverter ya isa, inverter yana fara aiki ta atomatik.Bayan shigar da aiki, inverter zai kula da fitarwa na tsarin hasken rana a kowane lokaci.Matukar ƙarfin fitarwa na tsarin hasken rana ya fi ƙarfin fitarwa da aikin inverter ke buƙata, injin inverter zai ci gaba da aiki;Har ila yau, injin inverter na iya gudu a ranakun damina.Lokacin da fitarwa na tsarin hasken rana ya zama ƙarami kuma fitarwar inverter yana kusa da 0, mai inverter yana samar da yanayin jiran aiki.
2.
