Tam sim no, kev lag luam semiconductor tseem nyob hauv lub voj voog qis,kev lag luam chipyog feem ntau ntsib lub siab ntawm cov neeg muas zaub txiav kev txiav txim thiab poob cov khoom nqi, tab sis IGBT yog nyob rau hauv ob lub ntsiab kev siv ntawm hluav taws xob tsheb thiab hnub ci photovoltaic thov, chim siab ntawm cov khoom, tsis ntev los no tsis txaus loj, tsis tsuas yog tus nqi tau nce mus rau lub ntuj, kev lag luam tsis yog "tus nqi siab npaum li cas ntawm qhov teeb meem, tab sis tsuas yog tsis tuaj yeem yuav" los piav txog qhov xwm txheej tsis txaus.
IGBT yog tib pawg ntawm cov khoom siv semiconductor uas muaj peev xwm nce nws tus nqi thiab tshaj qhov kev thov txhua txoj hauv kev, feem ntau yog vim muaj cov khoom lag luam tsawg nyob rau theem no, tab sis kev tsim kho vwm ntawm lub hnub ci fais fab nroj tsuag, lawv cov inverters muaj qhov loj. Kev thov rau IGBTs, ua ke nrog kev thov siab rau IGBTs hauv tsheb fais fab, cov tuam txhab tsheb loj tau nquag snapped lawv.
Nws tau tshaj tawm tias IGBT yog lub zog hloov hluav taws xob, nrog lub koob npe nrov ntawm "lub zog hluav taws xob CPU", yog lub zog tsav hluav taws xob semiconductor lub zog tsim los ntawm BJT (bipolar junction transistor) thiab MOSFET (kub oxygen ib nrab teb cov nyhuv transistor), nrog rau qhov zoo. ntawm siab input impedance, siab withstand voltage thiab tsawg on-lub xeev voltage poob.
Nrog kev nce ntawm lub zog tshiab tsheb, qhov kev thov rau high voltage tau nce ntau heev, thiab IGBTs tau dhau los ua qhov tseem ceeb ntawm kev tsim kho kev lag luam.Tus naj npawb ntawm IGBTs siv nyob rau hauv ib lub tsheb fais fab yog siab li ntau pua, uas yog xya mus rau kaum npaug ntawm cov tsheb roj ib txwm muaj.Hauv cov ntawv thov kev lag luam, muaj AC servo motors, inverters, cua thiab hnub ci tsim hluav taws xob thiab lwm yam kev siv hluav taws xob ntsuab, thiab nyob rau hauv cov hluav taws xob siab, muaj cov kev tsheb ciav hlau ceev thiab lwm yam kev tsheb ciav hlau thiab daim phiaj siv hluav taws xob.
Raws li rau daim ntawv thov ntawmIGBTsnyob rau hauv lub hnub ci teb, nws yog nyob rau hauv lub inverter.Raws li lub zog hloov hluav taws xob, lub inverter tuaj yeem hloov lub zog khaws cia hauv lub hnub ci vaj huam sib luag mus rau qhov muaj hluav taws xob feem ntau, tsis muaj lub inverter, lub zog cog tsis tuaj yeem ua haujlwm thiab muaj qhov tseem ceeb hauv kev tsim kho lub hnub ci fais fab nroj tsuag.
Lub hnub ci kev lag luam tau taw qhia tias nrog kev hloov pauv ntawm lub hnub ci hluav taws xob tsim hluav taws xob ntau ntxiv, lub zog hluav taws xob siab tau ua lub hauv paus kev lag luam, thiab tuaj yeem txhim kho kev rov qab los ntawm kev nqis peev ntawm cov tswv lag luam fais fab, yog li ntau lub hnub ci inverters tam sim no import IGBT raws li kev lag luam. lub zog tivthaiv, qhov kev thov kuj tau pib vam meej.
Tham txog qhov luv ntawm IGBT?Moody's Thawj Tswj Hwm Ye Zhengxian bluntly hais tias tus nqi nce tsis yog qhov tshiab, tsis yog qhov teeb meem ntawm tus nqi siab, tab sis tsuas yog tsis tuaj yeem yuav, txoj kev tshawb fawb xaus lus tias nthwv dej ntawm kev tsis txaus yuav txuas ntxiv mus ib ntus.
Tsis tas li ntawd, raws li cov khoom lag luam, Hanlei tau nce tus nqi tsim khoom ntawm IGBT cov kab ntau lawm los ntawm 10% ua ntej lub xyoo no, thiab thaum lub wafer foundry muab feem ntau hloov rov qab, Hanlei nce tus nqi tawm tsam tus qauv, qhia txog cov kev lag luam kub. .
Raws li "2023 Q1 Chip Market Report" cov ntaub ntawv tso tawm los ntawm Yav Tom Ntej Electronics thaum Lub Ob Hlis 17, 2023, IGBT Q1 ntawm ST (STMicroelectronics), Microsemi, Infineon, IXYS thiabFairchild(Fairchild Semiconductor), tsib lub npe tseem ceeb, tseem nyob hauv ib yam li lub sijhawm xa khoom ntawm 2022 Q4, nrog rau lub sijhawm xa khoom tseem nruj ntawm 54 lub lis piam ntev tshaj plaws.
Tshwj xeeb, hauv thawj peb lub hlis twg ntawm 2023, ST's IGBT lub sij hawm coj mus kuaj yog 47-52 lub lis piam, Microsemi's IGBT lub sij hawm coj mus kuaj yog 42-52 lub lis piam, IXYS lub sij hawm IGBT yog 50-54 lub lis piam, Infineon's IGBT lead lub sij hawm yog 39-50 lub lis piam, thiab Fairchild lub sijhawm IGBT yog 39-52 lub lis piam.Txawm li cas los xij, cov khoom xa tuaj thiab cov nqi sib txawv ntawm cov 5 lub npe loj no ruaj khov, tsis muaj kev nce siab.
Kev lag luam tsom xam, muaj ob lub laj thawj tseem ceeb rau qhov tsis txaus ntawm IGBTs, thawj yog qhov feem pua ntawm hnub ci inverters siv IGBTs tau nce ntau.Qhov thib ob yog tias kev lag luam semiconductor tam sim no nyob rau hauv lub sijhawm hloov kho, tsis yog tsuas yog lub peev xwm txwv xwb, tab sis kuj muaj ntau lub peev xwm tau raug tshem tawm los ntawm cov tuam txhab hluav taws xob tsheb, uas ua rau muaj qhov tsis txaus loj ntawm IGBTs hauv qab cov neeg coob coob.
