Menene aMOSFET?
MOSFET, cikakken sunan Sinanci shine ƙarfe-oxide semiconductor filin tasirin transistor.Saboda ƙofofin wannan filin tasirin transistor an keɓe shi da wani Layer na insulating, ana kuma kiran shi transistor filin filin gate.MOSFET za a iya raba iri biyu: "N-type" da "P-type" bisa ga polarity na "tashar" (aiki m), yawanci kuma ake kira N MOSFET da P MOSFET.
MOSFET da kanta tana da diode nata na parasitic, wanda ake amfani da shi don hana MOSFET ƙonewa lokacin da VDD ta cika ƙarfin wuta.Domin kafin overvoltage ya haifar da lalacewa ga MOSFET, diode ya sake rushewa da farko kuma ya jagoranci babban wutar lantarki zuwa ƙasa, ta yadda ya hana MOSFET daga ƙonewa.
Menene IGBT?
IGBT (Insulated Gate Bipolar Transistor) na'ura ce mai haɗaɗɗiyar na'ura wacce ta ƙunshi transistor da MOSFET.
Alamun kewayawa na IGBT ba su haɗa kai ba tukuna.Lokacin zana zane-zane, alamomin triode da MOSFET gabaɗaya ana aro.A wannan lokacin, zaku iya yanke hukunci ko IGBT ne ko MOSFET daga ƙirar da aka yiwa alama akan zane.
A lokaci guda kuma, ya kamata ku kula da ko IGBT yana da diode jiki.Idan ba a yi alama a kan hoton ba, ba yana nufin cewa babu shi ba.Sai dai in bayanan hukuma sun nuna akasin haka, wannan diode yana nan.Diode na jikin da ke cikin IGBT ba parasitic bane, amma an saita shi musamman don kare juriyar ƙarfin jurewar IGBT.Ana kuma kiranta FWD (freewheeling diode).
Tsarin ciki na biyu ya bambanta
Sandunan MOSFET guda uku sune tushen (S), lambatu (D) da kofa (G).
Sanduna uku na IGBT sune masu tara (C), emitter (E) da kofa (G).
Ana gina IGBT ta ƙara ƙarin Layer zuwa magudanar MOSFET.Tsarinsu na ciki shine kamar haka:
Filayen aikace-aikacen biyu sun bambanta
Tsarin ciki na MOSFET da IGBT sun bambanta, wanda ke ƙayyade filayen aikace-aikacen su.
Saboda tsarin MOSFET, yawanci yana iya cimma babban halin yanzu, wanda zai iya isa KA, amma ƙarfin jurewar da ake buƙata ba shi da ƙarfi kamar IGBT.Babban wuraren aikace-aikacensa shine sauya kayan wuta, ballasts, dumama shigar da wutar lantarki, inverter walda injina, samar da wutar lantarki da sauran filayen samar da wutar lantarki mai girma.
IGBT na iya samar da wuta mai yawa, halin yanzu da ƙarfin lantarki, amma mitar ba ta da yawa.A halin yanzu, saurin sauyawa na IGBT zai iya kaiwa 100KHZ.Ana amfani da IGBT sosai a injunan walda, inverters, masu sauya mitar mita, kayan wutar lantarki na lantarki, dumama shigar da ultrasonic da sauran filayen.
Babban fasali na MOSFET da IGBT
MOSFET yana da halaye na babban shigarwar impedance, saurin sauyawa mai sauri, kwanciyar hankali mai kyau na thermal, ikon sarrafa wutar lantarki, da sauransu.
A matsayin sabon nau'in na'urar semiconductor na lantarki, IGBT yana da halaye na babban shigarwar shigarwa, ƙarancin ikon sarrafa wutar lantarki, da'irar sarrafawa mai sauƙi, juriya mai girma, da babban haƙuri na yanzu, kuma an yi amfani dashi sosai a cikin nau'ikan lantarki daban-daban.
Ana nuna madaidaicin da'irar IGBT a cikin hoton da ke ƙasa.IGBT haƙiƙa shine haɗin MOSFET da transistor.MOSFET tana da rashin lahani na babban juriya, amma IGBT ta shawo kan wannan gazawar.IGBT har yanzu yana da ƙarancin juriya a babban ƙarfin lantarki..
Gabaɗaya, fa'idar MOSFET ita ce tana da kyawawan halaye masu ƙarfi kuma tana iya aiki a mitar ɗaruruwan kHz har zuwa MHz.Rashin hasara shi ne cewa a kan juriya yana da girma kuma yawan amfani da wutar lantarki yana da girma a cikin babban ƙarfin lantarki da yanayin halin yanzu.IGBT yana aiki da kyau a cikin ƙananan mitar da manyan yanayi, tare da ƙananan juriya da ƙarfin juriya.
Zaɓi MOSFET ko IGBT
A cikin da'irar, ko za a zabi MOSFET a matsayin wutar lantarki ko IGBT tambaya ce da injiniyoyi sukan ci karo da su.Idan aka yi la'akari da abubuwa kamar ƙarfin lantarki, halin yanzu, da ikon sauya tsarin, za a iya taƙaita waɗannan abubuwan:
Sau da yawa mutane suna tambaya: "Shin MOSFET ko IGBT yafi kyau?"Hasali ma, babu bambanci mai kyau ko mara kyau a tsakanin su biyun.Abu mafi mahimmanci shine ganin ainihin aikace-aikacen sa.
Idan har yanzu kuna da tambayoyi game da bambanci tsakanin MOSFET da IGBT, kuna iya tuntuɓar Olukey don cikakkun bayanai.
