Dab tsi yog qhov siab tshaj plaws transistor?

Txheej txheem cej luam ntawm transistor ntsuam xyuas
Cov nqi ntsuas ntawm cov transistors, suav nrog qhov siab tshaj plaws kev khiav hauj lwm voltage, siab tshaj plaws tam sim no, siab tshaj plaws tso cai dissipated hwj chim, thiab siab tshaj plaws kev khiav hauj lwm qhov kub thiab txias, yog txiav txim los ntawm tej yam xws li cov khoom vaj tse, structural tsim, tsim theem, thiab manufacturing txheej txheem ntawm lub transistor. Cov nqi ntsuas no tsis tsuas yog cuam tshuam qhov kev ua tau zoo ntawm cov transistors, tab sis kuj ncaj qha cuam tshuam rau kev ruaj ntseg thiab kev ntseeg siab ntawm transistors hauv kev siv tswv yim.
Hom transistor nrog tus nqi siab tshaj plaws
Ntawm ntau hom transistors, Giant Transistor (GTR) sawv tawm los ua ib qho ntawm cov khoom siv hluav taws xob siab tshaj plaws vim nws qhov hluav taws xob siab thiab siab tam sim no tsis kam. GTR, tseem hu ua Hwj chim BJT, nws yog ib tug bipolar hlws ris transistor (BJT) nrog nws tus kheej tig tawm muaj peev xwm, dav siv nyob rau hauv nruab nrab muaj peev xwm thiab nruab nrab zaus circuits xws li cov khoom siv fais fab, lub cev muaj zog tswj, thiab dav inverters.
Kev piav qhia ntxaws txog tus nqi ntsuas
1. Kev ua haujlwm siab tshaj plaws
Qhov siab tshaj plaws kev khiav hauj lwm voltage ntawm GTR yog qhov siab tshaj plaws tus nqi ntawm cov khoom siv hluav taws xob uas nws tuaj yeem tiv taus, tseem hu ua cov khoom tawg hluav taws xob. Qhov kev ntsuas no tsis tsuas yog txawv nyob ntawm lub cuab yeej, tab sis txawm rau tib lub cuab yeej, nws kuj tseem tuaj yeem hloov pauv vim muaj qhov sib txawv ntawm lub hauv paus Circuit Court. Tam sim no, qee qhov high-end GTRs ntawm kev ua lag luam muaj qhov ntsuas qhov siab tshaj plaws ntawm kev ua haujlwm ntawm 1800V lossis siab dua, uas ua rau lawv ua haujlwm ruaj khov hauv qhov chaw muaj hluav taws xob siab.
2. Qhov siab tshaj plaws tso cai tam sim no ntawm cov khoom siv
Qhov siab tshaj plaws tso cai tam sim no (ICM) yog qhov nruab nrab ntawm qhov siab tshaj plaws DC lossis AC tam sim no uas GTR tuaj yeem tiv taus raws li kev ua haujlwm ib txwm muaj. Qhov kev ntsuas no ncaj qha txiav txim siab txog kev ua haujlwm tam sim no ntawm GTR. Txhawm rau kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm GTR nyob rau lub sijhawm ntev, tus nqi siv tam sim no yuav tsum qis dua li qhov ntsuas no. Tsis tas li ntawd, qhov ntsuas tus nqi ntawm cov mem tes tam sim no kuj yog qhov tseem ceeb ntawm GTR, uas qhia txog GTR lub peev xwm los tiv thaiv cov mem tes loads.
3. Qhov siab tshaj plaws tso cai dissipated hwj chim
Qhov siab tshaj plaws tso cai dissipated hwj chim (PCM) yog hais txog lub zog dissipated sib haum mus rau qhov siab tshaj plaws kev sib tshuam kub ntawm GTR. Vim tias cov cua sov tsim tawm thaum lub sijhawm ua haujlwm ntawm GTR, qhov loj ntawm nws lub zog dissipated ncaj qha cuam tshuam rau nws cov cua kub dissipation kev ua tau zoo thiab ruaj khov. GTRs nrog cov nqi ruaj khov feem ntau muaj qhov zoo dua cov cua kub dissipation tsim kom ntseeg tau tias kev ua haujlwm ruaj khov nyob rau hauv high-power loads.
4. Ua haujlwm kub siab tshaj plaws
Qhov siab tshaj plaws ua haujlwm kub sib txuas (TJM) yog qhov siab tshaj plaws sab hauv uas GTR tuaj yeem tiv taus. Qhov kev ntsuas no yog txiav txim siab los ntawm cov khoom xws li cov khoom siv semiconductor, cov txheej txheem passivation ntawm cov khoom siv, cov khoom ntim zoo, thiab kev ntseeg siab. GTRs nrog cov nqi ruaj khov siab feem ntau muaj qhov siab tshaj qhov kev khiav hauj lwm qhov kub thiab txias, uas txhais tau tias lawv tuaj yeem ua haujlwm ntawm qhov kub thiab txias dua yam tsis muaj kev puas tsuaj.
Daim ntawv thov ntawm cov transistor nrog cov nqi siab tshaj plaws
Lub transistor nrog tus nqi siab tshaj plaws muaj cov ntawv thov dav dav hauv thaj chaw xws li hluav taws xob hluav taws xob, kev lag luam automation, thiab lub zog tshiab. Piv txwv li, hauv kev lag luam hluav taws xob hluav taws xob, tus nqi ruaj khov GTR tuaj yeem siv rau hauv high-voltage direct tam sim no kis tau tus mob, lub zog hloov dua siab tshiab thiab lwm yam systems los txhim kho system efficiency thiab stability; Hauv kev lag luam automation, lawv tuaj yeem siv rau hauv cov tshuab xws li kev tswj xyuas lub cev muaj zog thiab kev tswj xyuas qhov sib txawv ntawm qhov ceev kom ua tiav kev tswj hwm thiab kev txuag hluav taws xob; Nyob rau hauv lub tshav pob ntawm lub zog tshiab, tus nqi ruaj khov GTR tuaj yeem siv rau hauv cov khoom siv xws li hnub ci photovoltaic inverters thiab cua fais fab converters los txhim kho lub zog conversion efficiency thiab kev pab lub neej.
