Yog hais tias lub transistor tuaj yeem hu ua qhov kev tsim khoom loj tshaj plaws ntawm lub xyoo pua 20th, ces tsis muaj kev ntseeg tias qhovMOSFET nyob rau hauv uas ib tug loj deal ntawm credit. Xyoo 1925, ntawm cov hauv paus ntsiab lus ntawm MOSFET patents luam tawm xyoo 1959, Bell Labs tau tsim lub hauv paus ntsiab lus ntawm MOSFET raws li kev tsim qauv. Txog niaj hnub no, loj rau lub zog hloov pauv, me me rau lub cim xeeb, CPU thiab lwm yam khoom siv hluav taws xob cov khoom siv hluav taws xob, tsis muaj leej twg tsis siv rau MOSFET. Yog li tom ntej no peb nkag siab txog kev ua haujlwm ntawm cov qauv ntawm MOSFET nws! MOSFET lub npe tag nrho yog Hlau-Oxide-Semiconductor Field-Effect Transistor.
1. Cov haujlwm tseem ceeb ntawm MOSFETs
Cov ntsiab lus tseem ceeb ntawm MOSFET yog - semiconductor, thiab semiconductor yog ib hom khoom siv hlau, nws tuaj yeem ua hluav taws xob, tab sis qhov tseeb, nws kuj tuaj yeem raug insulated.MOSFET yog ib hom khoom siv semiconductor, peb xav tau nws kom paub txog kev ua haujlwm yooj yim. yog tsuas yog yuav tsum muaj peev xwm xyuas kom meej tias kev ncig ntawm lub voj voog, thiab tseem tuaj yeem paub txog lub voj voog ntawm kev thaiv.
2. Cov qauv tsim ntawm MOSFETs
MOSFET yog ib qho khoom siv hluav taws xob ntau yam vim nws lub rooj vag qis tsav lub zog, kev hloov pauv ceev thiab muaj zog ua haujlwm sib luag. Ntau lub zog MOSFETs muaj cov qauv ntsug ntsug ntev, nrog rau qhov chaw thiab ntws tawm hauv cov dav hlau sib txawv ntawm cov wafer, tso cai rau cov dej ntws loj thiab cov hluav taws xob siab.
3. MOSFETs yog siv los ua cov khoom siv hluav taws xob loj hauv ob lub teb
(1), qhov yuav tsum tau ua ntawm kev khiav hauj lwm zaus ntawm 10kHz thiab 70kHz, thaum lub hwj chim tso zis yuav tsum tsawg tshaj li 5kw nyob rau hauv lub tshav pob, nyob rau hauv feem ntau ntawm cov ntaub ntawv no, txawm lub IGBT thiab lub hwj chim.MOSFETs tuaj yeem ua tiav cov haujlwm sib xws, tab sis lub zog MOSFETs zoo li tso siab rau qhov kev hloov pauv qis dua, qhov loj me thiab tus nqi qis los ua qhov kev xaiv zoo tshaj plaws, cov ntawv thov sawv cev yog LCD TV boards, induction cookers thiab lwm yam.
(2), qhov yuav tsum tau ua ntawm kev khiav hauj lwm zaus yog siab tshaj qhov zaus siab tshaj plaws uas tuaj yeem ua tiav los ntawm lwm cov khoom siv hluav taws xob, qhov siab tshaj plaws tam sim no feem ntau yog nyob rau hauv 70kHz los yog li ntawd, nyob rau hauv cheeb tsam no lub hwj chim.MOSFET tau dhau los ua qhov kev xaiv nkaus xwb, cov ntawv thov sawv cev yog inverters, khoom siv suab, thiab lwm yam.
