Dab tsi yog kev siv ntawm silicon carbide?
Silicon carbide (SiC), raws li cov khoom siv semiconductor tshiab, muaj qhov zoo ntawm silicon carbide: ntim me me, muaj txiaj ntsig zoo, ua tiav kev tshem tawm ntawm kev hloov pauv, tsis muaj dej ntws tam sim no, ntau zaus hloov pauv ntau dua li cov txheej txheem semiconductors (ntshiab silicon semiconductors), thiab muaj peev xwm. ua hauj lwm saum 125 ° C hlws ris kub ntawm silicon carbide qauv.
Lub silicon carbide rau pem hauv ntej tus neeg xyuas pib ua qhov kev hloov pauv sai ntawm qhov siab tam sim no thiab rov qab txiav tawm kV voltage, thiab qhov kev ua tau zoo no tsim nyog sim. Thawj daim ntawv thov kev vam meej ntawm SiC thiab daim ntawv thov tseem ceeb ntawm cov plaub hau diodes yog siv nyob rau hauv tsheb headlights thiab lwm yam twj paj nruag vaj huam sib luag teeb pom kev zoo. Lwm qhov kev lag luam suav nrog hloov cov khoom siv hluav taws xob thiab Schottky barrier diodes. Cov ntawv thov yav tom ntej suav nrog hybrid tsheb, lub zog hloov pauv (kom txo qhov ntim ntawm cov khoom siv ua ntej) thiab AC / DC lub cev muaj zog tswj.
Cov ntawv thov xav tau ntau dua no tseem tsis tau ua lag luam vim lawv xav tau cov ntaub ntawv zoo thiab cov khoom lag luam loj los txo cov nqi. Thoob plaws ntiaj teb, cov nyiaj tshawb fawb tseem ceeb tau nqis peev hauv cov tuam txhab, cov chaw sim, thiab tsoomfwv cov chaw ua kom SiC siv tau zoo dua. Qee cov kws tshaj lij kwv yees tias kev lag luam, kev lag luam thiab kev siv tub rog ntawm SiC thev naus laus zis yuav dhau los ua qhov tseeb hauv 2 txog 5 xyoo lossis ntau dua.
