Quwadda Sare ee IGBT Aluminium Heat Wasdhiga

Xakamaynta mootada dahaarka ah ee Gate Bipolar Transistor (Transistor Gate Bipolar Transistor, IGBT) waxqabadka kala daadinta kulaylka ayaa si isa soo taraysa u noqonaysa matoor IGBT hadda soo galaya suuqa elektiroonigga ah ee tamarta warshadaha, sida (alxanka) weelka kulaylka, rogaha jiidista, wadista baabuurta, iwm.Ruiqifengwaxay siisaa alaabada isku dhafka kulaylka IGBT taasoo u oggolaanaysa IGBT inay ku shaqeyso meel heerkul sare ah iyadoo lagu ilaalinayo heerkulka shaqada ee meel badbaado leh iyadoo la isku darayo iska caabbinta kulaylka hoose iyo Silikon Vce(on).

IGBT inta badan kiisaska waxay la shaqeysaa qalab koronto sare leh, awoodda sare waxay ka dhigan tahay kulaylka sareeyo, IGBT waxay u socotaa awoodda weyn, soo noqnoqda sare, fududahay in la wado, lumis hoose, modular, waxay tilmaamaysaa jihada horumarka, marka la barbardhigo qalabka kale ee korontada. Weelka kulaylka IGBT wuxuu leeyahay kalsooni sare, wadis fudud, fududahay in la ilaaliyo, ma jiro wareegga wareegga iyo inta jeer ee beddelidda, sidaas awgeed kuleylka IGBT ee suuqa elektiroonigga ah wuxuu noqdaa mid lagama maarmaan ah.Si loo gaaro waxqabadyadan sare, habab badan ayaa loo isticmaalaa wareegyada isku dhafan, sida epitaxy, implantation ion, lithography ganaax, iwm. Sanadihii la soo dhaafay, waxqabadka qalabka IGBT ee qalabka kuleylka kuleylka ayaa si degdeg ah loo hagaajiyay, hadda la qiimeeyay ayaa waxa uu gaadhay boqollaal amperes, tamarta adkaysiga u ah in ka badan 1500V, walina way soo hagaagaysaa.Maadaama aaladaha IGBT ay leeyihiin astaamo togan oo ah diode-ka PIN, astaamaha p-channel power IGBT weelka kulaylku aad ugama duwana kan n-channel IGBT, kaas oo aad ugu habboon in la qaato qaab-dhismeed dhammaystiran oo codsiga ah, sidaas awgeed way sii fidaysaa. codsigeeda dhanka ac iyo tignoolajiyada xakamaynta dhijitaalka ah.Faa'iidada ugu weyn ee IGBT waa in ay u adkeysan karto shoogga hadda jira ama xaalad wareeg ah oo gaaban.Xidhiidhka isbar-bar yaaca ah dhib malaha oo xidhiidhkiisu waa sahlan yahay daahitaanka gaabni awgeed.

Hababka kala wareejinta kulaylka IGBT inta badan waxaa ka mid ah qaboojinta hawada, qaboojinta biyaha, saxanka kulaylka naxaasta ama weelka kulaylka aluminium.Kuleylkeeda kuleylkeedu wuxuu ku salaysan yahay mabda'a aasaasiga ah ee wareejinta kulaylka, dariiqa socodka kulaylka leh heerkulka ugu hooseeya ayaa loogu talagalay qalabka si kulaylka uu soo saaro qalabku sida ugu dhakhsaha badan ee suurtogalka ah, si loo hubiyo in gudaha gudaha heerkulka isgoysyada qalabka waxaa had iyo jeer lagu hayaa gudaha heerkulka isgoysyada la ogol yahay.

Waqtigan xaadirka ah, tuubada kulaylka ee IGBT ee hadda jirta ee suuqa ku jirta inta badan waxaa ka mid ah finta kulaylka, tuubada kulaylka iyo substrate, kaas oo substrate-ka la siiyo tiro ka mid ah grooves barbar socda, ka dibna jeexdin waxaa lagu alxanayaa alxanka qaybta uumi-baxa tuubada kulaylka.Tiknoolajiyada saxanka kulaylka ee IGBT ee jira, qaybta uumi-baxa ee tuubada kulaylka ayaa lagu aasay godka substrate-ka oo si toos ah uguma habboona dusha IGBT.Habka shaqada, kulaylka ka imanaya dusha IGBT ayaa marka hore laga dhoofiyaa substrate ka dibna loo wareejiyaa tuubada kulaylka iyo weelka kulaylka.Ugu dambeyntii, kulaylka ka soo baxa kulaylka waxaa loo wareejiyaa hawada iyada oo la isku dhejiyo.Sababtoo ah substrate-ka laftiisa ayaa leh caabbinta kulaylka, iyo isku-dhafka kulaylka kuleylka ee tuubada kulaylka ayaa aad uga sarreeya tan saldhigga, waxtarka kuleylka kuleylka kuleylka kuleylka ayaa xaddidan, waxqabadka kuleylka kuleylka ayaa hoos u dhacaya.Weelka kulaylka IGBT waxay u wareejin kartaa kulaylka si siman oo ka soo baxa substrate ilaa fin, kaas oo si wax ku ool ah u xalin kara dhibaatada kuleylka kuleylka sare, ma aha oo kaliya waxtarka sare, laakiin sidoo kale qaab dhismeed isku dhafan oo aan lahayn qaybo dhaqdhaqaaqa, taas oo si dhab ah u xaqiijin karta dayactirka- bilaasha.
