Menene inverter?

Injin canza wutar lantarki na DC zuwa AC ne, wanda a zahiri tsari ne na juyawar wutar lantarki tare da mai canza wutar lantarki. Mai canza wutar lantarki na AC na grid ɗin wutar lantarki zuwa fitarwa mai ƙarfi na DC 12V, yayin da mai canza wutar lantarki ke canza fitowar wutar lantarki na DC 12V ta hanyar mai adaftar zuwa AC mai ƙarfin lantarki mai ƙarfi; dukkan sassan kuma suna amfani da fasahar daidaitawar faɗin bugun jini (PWM) da aka fi amfani da ita. Babban ɓangaren shine mai sarrafawa mai haɗa PWM, mai adaftar yana amfani da UC3842, kuma mai canza wutar lantarki yana amfani da guntu na TL5001. Matsakaicin ƙarfin lantarki na TL5001 shine 3.6 ~ 40V, kuma yana da amplifier na kuskure, mai daidaitawa, mai juyawa, janareta na PWM tare da sarrafa yankin matattu, da'irar kariyar wutar lantarki mai ƙarancin ƙarfi da kuma da'irar kariyar da'ira ta gajere.

Sashen hanyar haɗawa ta shigarwa: Sashen shigarwar yana da sigina 3, VIN na shigarwar DC 12V, ENB mai kunna wutar lantarki da siginar sarrafa wutar lantarki ta Panel DIM. Adaftar yana samar da VIN, kuma ƙarfin ENB yana samar da shi ta MCU akan motherboard, kuma ƙimarsa 0 ko 3V ne. Lokacin da ENB = 0, inverter baya aiki, kuma lokacin da ENB = 3V, inverter yana cikin yanayin aiki na yau da kullun; kuma ƙarfin DIM yana samar da shi ta motherboard, kuma kewayon bambancinsa yana tsakanin 0 da 5V. Ana mayar da ƙimar DIM daban-daban zuwa ƙarshen martani na mai sarrafa PWM, kuma ƙarfin da inverter ke bayarwa ga kaya shima zai bambanta. Ƙaramin ƙimar DIM, mafi girman fitowar wutar lantarki ta inverter.

Madaurin farawa na ƙarfin lantarki: Lokacin da ENB ya yi yawa, ana fitar da babban ƙarfin lantarki don haskaka bututun hasken baya na Panel.

Mai sarrafa PWM: Ya ƙunshi ayyuka masu zuwa: ƙarfin lantarki na ciki, ƙara ƙarfin kuskure, oscillator da PWM, kariyar ƙarfin lantarki mai yawa, kariyar ƙarancin wutar lantarki, kariyar da'ira ta gajere, da kuma transistor na fitarwa.

Canjin DC: Da'irar canza wutar lantarki ta ƙunshi bututun MOS da inductor na ajiyar makamashi. Ana ƙara ƙarfin shigarwar ta hanyar amplifier na turawa kuma yana tura bututun MOS don yin aikin sauyawa, don haka ƙarfin wutar lantarki na DC yana caji da fitar da inductor, ta yadda ɗayan ƙarshen inductor ɗin zai iya samun ƙarfin AC.

Da'irar juyawa da fitarwa ta LC: tabbatar da ƙarfin lantarki na 1600V da ake buƙata don fitilar ta fara, kuma rage ƙarfin lantarki zuwa 800V bayan fitilar ta fara.

Ra'ayin wutar lantarki na fitarwa: lokacin da nauyin ke aiki, ana mayar da wutar lantarki ta samfurin don daidaita fitowar wutar lantarki na inverter I.

aiki
Injin canza wutar lantarki (inverter) yana canza wutar lantarki ta DC (batir, batirin ajiya) zuwa wutar AC (galibi 220v50HZ sine ko square wave). A taƙaice, injin canza wutar lantarki (inverter) na'ura ce da ke canza wutar lantarki kai tsaye (DC) zuwa wutar lantarki mai canzawa (AC). Ya ƙunshi gadar inverter, dabaru na sarrafawa da kuma da'irar tacewa.
A taƙaice dai, inverter na'ura ce ta lantarki wadda ke canza wutar lantarki mai ƙarancin wutar lantarki (volt 12 ko 24 ko volt 48) zuwa wutar AC mai ƙarfin volt 220. Domin kuwa wutar AC mai ƙarfin volt 220 yawanci ana gyara ta zuwa wutar DC don amfani, kuma rawar da inverter ke takawa akasin haka ne, shi ya sa ake kiranta. A zamanin "motsi", ofishin wayar hannu, sadarwa ta wayar hannu, nishaɗi da nishaɗi. Lokacin da ake tafiya, ba wai kawai ana buƙatar wutar lantarki mai ƙarancin wutar lantarki daga batura ko batirin ajiya ba, har ma da wutar lantarki mai ƙarfin volt 220, wanda ba makawa ne a rayuwar yau da kullun. Inverters na iya biyan waɗannan buƙatu.
