Cov khoom siv hluav taws xob sab saud ntawm cov khoom siv hluav taws xob khaws cia muaj xws li IGBT, capacitance, tsis kam, hluav taws xob tsis kam, PCB, thiab lwm yam. Ntawm lawv, IGBT tseem yog nyob ntawm kev xa khoom. Tseem muaj qhov sib txawv ntawm IGBT hauv tsev ntawm qib thev naus laus zis thiab qib ua hauv ntiaj teb. Txawm li cas los xij, nrog txoj kev loj hlob sai ntawm Tuam Tshoj lub zog cia kev lag luam, cov txheej txheem domesticization ntawm IGBT kuj tseem xav kom nrawm.

IGBT lub zog cia daim ntawv thov tus nqi

Piv nrog rau photovoltaic, tus nqi ntawm lub zog cia IGBT yog qhov siab. Lub zog cia siv ntau dua IGBT thiab SIC, suav nrog ob qhov txuas: DCDC thiab DCAC, suav nrog ob txoj kev daws teeb meem, uas yog cov khoom siv kho qhov muag sib xyaw thiab cais lub zog cia. Kev ywj pheej lub zog cia, tus nqi ntawm cov khoom siv hluav taws xob semiconductor yog li 1.5 npaug ntawm photovoltaic. Tam sim no, kho qhov muag cia yuav suav txog ntau dua 60-70%, thiab cov khoom siv hluav taws xob sib cais tso nyiaj rau 30%.

IGBT muaj ntau yam ntawm daim ntawv thov txheej, uas yog qhov zoo dua li MOSFET hauv lub zog cia inverter. Hauv cov haujlwm tiag tiag, IGBT tau maj mam hloov MOSFET ua cov cuab yeej tseem ceeb ntawm photovoltaic inverters thiab cua zog tsim. Kev loj hlob sai ntawm lub zog tshiab lub zog tsim kev lag luam yuav dhau los ua lub zog tshiab rau kev lag luam IGBT.

IGBT yog cov cuab yeej tseem ceeb rau kev hloov hluav taws xob thiab kev sib kis

IGBT tuaj yeem nkag siab tag nrho raws li lub transistor uas tswj hluav taws xob ob-txoj kev (ntau-directional) ntws nrog valve tswj.

IGBT yog qhov sib xyaw ua ke tag nrho-control voltage-driven fais fab semiconductor ntaus ntawv tsim los ntawm BJT bipolar triode thiab insulating grid field effect raj. Qhov zoo ntawm ob yam ntawm kev poob siab.

Kev hloov pauv ntawm IGBT yog tsim cov channel los ntawm kev ntxiv qhov zoo rau lub rooj vag voltage los muab lub hauv paus tam sim no rau PNP transistor los tsav IGBT. Hloov pauv, ntxiv qhov hluav taws xob rov qab qhov rooj kom tshem tawm cov channel, ntws los ntawm qhov rov qab puag tam sim no, thiab tig IGBT tawm. Txoj kev tsav tsheb ntawm IGBT yog qhov pib zoo ib yam li ntawm MOSFET. Nws tsuas yog yuav tsum tau tswj lub tswv yim ncej N ib-channel MOSFET, yog li nws muaj cov yam ntxwv siab impedance.

IGBT yog cov cuab yeej tseem ceeb ntawm kev hloov pauv hluav taws xob thiab kev sib kis. Nws yog feem ntau hu ua "CPU" ntawm cov khoom siv hluav taws xob hluav taws xob. Raws li lub teb chaws txoj kev lag luam tawm tswv yim, nws tau siv dav hauv cov cuab yeej siv hluav taws xob tshiab thiab lwm yam kev lag luam.

IGBT muaj ntau yam zoo xws li cov input impedance siab, tsis tshua muaj zog tswj, yooj yim tsav Circuit Court, ceev hloov ceev, loj-lub xeev tam sim no, txo kev hloov siab, thiab me me poob. Yog li ntawd, nws muaj qhov zoo tshaj plaws hauv kev lag luam ib puag ncig tam sim no.

Yog li ntawd, IGBT tau dhau los ua qhov tseem ceeb tshaj plaws ntawm kev lag luam hluav taws xob semiconductor tam sim no. Nws yog dav siv nyob rau hauv ntau qhov chaw xws li kev tsim hluav taws xob tshiab, tsheb hluav taws xob thiab cov khoom siv hluav taws xob, cov nkoj hluav taws xob, DC kis tau tus mob, lub zog cia, muaj hluav taws xob tswj thiab txuag hluav taws xob.

Kev faib tawm IGBT

Raws li cov khoom sib txawv, IGBT muaj peb hom: ib leeg-pipe, IGBT module thiab ntse zog module IPM.

(Charge pawg) thiab lwm qhov chaw (feem ntau xws li cov khoom lag luam modular muag hauv khw tam sim no). Lub tshuab hluav taws xob ntse IPM feem ntau yog siv dav hauv cov khoom siv hauv tsev dawb xws li inverter cua txias thiab zaus hloov tshuab ntxhua khaub ncaws.

Nyob ntawm qhov voltage ntawm daim ntawv thov scenario, IGBT muaj hom xws li ultra-low voltage, low voltage, medium voltage thiab high voltage.

Ntawm lawv, IGBT siv los ntawm cov tsheb tshiab lub zog, kev tswj hwm kev lag luam, thiab cov khoom siv hauv tsev yog qhov nruab nrab ntawm qhov nruab nrab, thaum kev tsheb ciav hlau, kev tsim hluav taws xob tshiab thiab cov phiajcim ntse muaj qhov xav tau ntau dua, feem ntau yog siv high-voltage IGBT.

IGBT feem ntau tshwm nyob rau hauv daim ntawv ntawm modules. IHS cov ntaub ntawv qhia tau hais tias qhov kev faib ua feem ntawm cov modules thiab ib lub raj yog 3: 1. Lub module yog ib qho khoom siv semiconductor modular tsim los ntawm IGBT nti thiab FWD (txuas ntxiv diode nti) los ntawm ib qho kev hloov kho Circuit Court choj, thiab los ntawm cov yas thav ntawv, substrates thiab substrates. , lwm.
