Lub tshuab tshiab ua rau kev lag luam
Rau 60 xyoo, Mitsubishi Electric tau tuav nws txoj haujlwm hauv kev lag luam rau kev sib nraus thiab kev tshawb fawb thiab kev tsim kho.
Raws li lub hauv paus ntawm lub hwj chim Cheebtsam, qhov tseem ceeb ntawm IGBT chips yog nws tus kheej. Nyob rau hauv kev loj hlob ntawm qhov tseeb technology ntawm fais fab tuag semiconductors, Mitsubishi Electric lub IGBT nti technology tau nce. Qhov thib peb tiam IGBT yog ib hom kab xaum tsev, ib tiam neeg IGBT yog ib lub qauv kev sib tsoo, thib tsib cim yog CSTBTTM, thiab lub thib rau tiam yog ultra-nyias. CSTBTTM, kev siv xya lub cim IGBT yog ntau dua ua kom zoo dua thiab ultra-nyias CSTBTTM.
Los ntawm Performance Performance Index (FOM) ntawm IGBT nti, lub thib rau cim tau nce los ntawm 16 lub sij hawm piv nrog thawj tiam, thiab lub xya tiam tau nce los ntawm 26 lub sij hawm piv nrog thawj tiam. Los ntawm kev xav ntawm lub tshuab ntim tshuab, nyob rau hauv cov khoom siv tsawg DIPIPMTM, Mitsubishi Electric tau txais ib lub hnab ntim tshuaj molding. Hauv nruab nrab lub peev txheej khoom tsim thiab fais fab kev tsheb khoom, ib lub thawv ntawv pob tau txais yuav. Cov khoom muaj zog, tshwj xeeb tshaj yog cov siv los ntawm kev tsheb ciav hlau, kev ua haujlwm zoo tshaj plaws ntawm silicon carbide aluminium substrates yog siv, uas tom qab ntawd muab ntim rau hauv lub thawv ntawv.
Nyob rau tib lub sij hawm ntawm huab hwm coj ntau thiab khoom, Mitsubishi Electric kuj yog kev ua haujlwm rau cov lus nug ntxiv tawg tawg. Ib ncig ntawm 2022, Mitsubishi Electric yuav xav txog peev ntawm 12-nti hluav taws xob cov khoom tsim kab. Nyob rau hauv kev pom ntawm Dr. Gourab Majumdar, IGBT nti kev lag luam yuav loj hlob ntau hauv 2020-2022.
SiC yog cov tub ntxhais siv tshuab kev ua haujlwm ntawm cov cim txuas ntxiv mus rau lwm tiam. Piv nrog rau tsoos Si-IGBT modules, lub ntsiab zoo ntawm SiC zog modules yog tias switching losses yog heev txo. Rau cov kev siv inverter tshwj xeeb, qhov kev zoo dua no tuaj yeem txo cov inverter loj, nce qhov kev ua kom zoo zog thiab muaj kev hloov ntau zaus. Tam sim no, daim ntawv thov kev lag luam ntawm cov khoom siv hluav taws xob xws li SiC fais fab kev lag luam yog nthuav tawm. Txawm li cas los xij, vim tias muaj nqi dab tsi, txoj kev lag luam tam sim no ntawm SiC fais fab tuag yog qhov tsawg heev. Nrog rau kev siv technology, cov nqi ntawm silicon carbide yuav poob sai, thiab lub neej yav tom ntej yuav yog cov khoom hauv cov khoom hauv qhov hluav taws xob cov khoom hluav taws xob.
"Silicon carbide zog module tuaj yeem nthuav ntau daim ntawv sau npe vim nws qhov kev kub taub hau, kev siv zog tsawg thiab kev ntseeg siab. Silicon carbide yog qhov kev xaiv zoo tshaj plaws rau kev tshawb cov kev lag luam tshiab yav tom ntej, "said Dr. Gourab Majumdar.
Mitsubishi Electric tau qhia thawj lub cim ntawm silicon carbide fais fab ua txij thaum 2013. Nyob rau hauv qhov tseeb, raws li thaum ntxov li 1994, Mitsubishi Electric pib tsim SiC technology; txij thaum xyoo 2015, SiC fais fab tuag tau nkag ntau cov ntawv teb tshiab. Nyob rau hauv tib lub xyoo, Mitsubishi Electric tau tsim thawj lub koob thawm SiC zog, uas yog nruab nrog lub lag luam traction rau installation ntawm Shinkansen hauv Nyij Pooj. Mitsubishi Electric's SiC fais fab module khoom khis rau cov dej ntws los ntawm 15A mus rau 1200A thiab cov suab paj nruag ntawm 600V txog 3300V. Cov qauv no muaj tam sim no.
Vim qhov kev nce ceev hauv kev xav tau ntawm silicon carbide, Mitsubishi Electric tau siv nyob rau hauv 6-nti wafer ntau lawm kab hauv 2017 los txo cov chip loj nrog cov tshuab tshiab. Tam sim no, cov kab ntau lawm tab tom npaj raws li tau npaj cia, thiab ntau lawm yuav tsum yog xyoo 2019.
Lub zog electronics kev lag luam yuav tsum muaj rau cov khoom siv hluav taws xob muaj ntau dua hauv kev txhim kho kev lag luam thiab txo cov hwj huam loj, yog li cov tshiab SiCMOSFET fais fab yuav tau txais ntau dua thiab ntau daim ntaub ntawv. Yuav kom ua tau raws li qhov yuav tsum tau ua ntawm lub hwj huam hluav taws xob kev lag luam rau cov suab qis, kev ua haujlwm siab, kev loj me thiab kev nyhav, Mitsubishi Electric tau cog lus rau kev tshawb nrhiav thiab kev tsim cov khoom siv high-tech. Txoj kev loj hlob ntawm lub cim tshiab ntawm kev tshem tawm lub tsho tiv thaiv SiC MOSFET technology yog tsim tau, uas yuav ntxiv kev txhim kho ntawm kev sib raug zoo ntawm cov khoom siv ntawm lub caij ua haujlwm thiab kev tawm tsam, thiab cov kev npaj ua lag luam los ua lag luam tshiab SiC MOSFET module los ntawm 2020.
