Tare da ci gaban fasaha na zamani, fitowar inverter ya samar da sauƙi ga rayuwar kowa, to menene inverter?Ta yaya inverter ke aiki?Abokai masu sha'awar wannan, ku zo ku gano tare.
Menene inverter:
Inverter yana canza ikon DC (baturi, baturin ajiya) zuwa ikon AC (gaba ɗaya 220V, 50Hz sine wave).Ya ƙunshi gada inverter, sarrafa dabaru da kuma tace kewaye.An yi amfani da shi sosai a cikin injin kwandishan, gidajen wasan kwaikwayo, ƙafafun niƙa na lantarki, kayan aikin lantarki, injin ɗinki, DVD, VCD, kwamfutoci, TV, injin wanki, hoods, firiji, VCRs, massagers, fan, hasken wuta, da sauransu. zuwa yawan shigar motoci, ana iya amfani da injin inverter don haɗa baturi don fitar da na'urorin lantarki da kayan aiki daban-daban don aiki yayin fita aiki ko tafiya.
Ka'idodin aikin inverter:
Mai jujjuyawar wutar lantarki ce ta DC zuwa AC, wanda a zahiri tsari ne na juyar da wutar lantarki tare da mai canzawa.Mai jujjuya yana jujjuya wutar lantarki ta AC na grid ɗin wutar lantarki zuwa ingantaccen fitarwa na 12V DC, yayin da inverter yana jujjuya fitowar wutar lantarki ta 12V DC ta Adafta zuwa babban ƙarfin wutar lantarki mai ƙarfi AC;Dukan sassan biyu kuma suna amfani da fasaha mafi yawan amfani da fasahar bugun bugun jini (PWM).Babban ɓangaren sa shine haɗin haɗin PWM, Adaftar yana amfani da UC3842, kuma inverter yana amfani da guntu TL5001.Aiki irin ƙarfin lantarki kewayon TL5001 ne 3.6 ~ 40V.An sanye shi da amplifier na kuskure, mai daidaitawa, oscillator, janareta na PWM mai kula da yankin da ya mutu, da'irar kariyar ƙarancin wuta da kuma gajeriyar da'irar kariyar da'ira.
Bangaren shigar da bayanai:Akwai sigina 3 a cikin ɓangaren shigarwa, 12V DC shigarwar VIN, aiki yana ba da ƙarfin lantarki ENB da siginar sarrafawa na yanzu DIM.Ana samar da VIN ta hanyar Adafta, ENB na lantarki yana samar da MCU akan motherboard, ƙimarsa shine 0 ko 3V, lokacin da ENB=0, inverter baya aiki, kuma lokacin ENB=3V, inverter yana cikin yanayin aiki na yau da kullun;yayin da DIM ƙarfin lantarki Ya samar da babban allon, kewayon bambancinsa yana tsakanin 0 da 5V.Daban-daban dabi'u na DIM ana mayar da su zuwa tashar martani na mai sarrafa PWM, kuma na yanzu wanda mai jujjuyawa ya bayar zuwa kaya shima zai bambanta.Karamin ƙimar DIM, ƙaramin abin fitarwa na inverter.girma.
Da'irar fara wutar lantarki:Lokacin da ENB yake a babban matakin, yana fitar da babban ƙarfin lantarki don haskaka bututun hasken baya na Panel.
PWM mai kula:Ya ƙunshi ayyuka masu zuwa: ƙarfin magana na ciki, amplifier kuskure, oscillator da PWM, kariyar overvoltage, kariya mara ƙarfi, gajeriyar kariyar da'ira, da transistor fitarwa.
Canza DC:Da'irar jujjuyawar wutar lantarki ta ƙunshi bututun sauya MOS da inductor ajiyar makamashi.Inductor yana ƙara ƙarfin bugun jini ta hanyar tura-pull amplifier sannan ya tura bututun MOS don aiwatar da canjin aiki, ta yadda wutar lantarki ta DC ta yi caji da fitar da inductor, ta yadda ɗayan ƙarshen inductor ya sami ƙarfin AC.
LC oscillation da fitarwa kewaye:tabbatar da wutar lantarki 1600V da ake buƙata don fitilar ta fara, da kuma rage ƙarfin lantarki zuwa 800V bayan an fara fitilar.
Ra'ayin wutar lantarki na fitarwa:Lokacin da nauyin ke aiki, ana dawo da ƙarfin samfurin don daidaita ƙarfin wutar lantarki na inverter.
