HPSI SiC wafer dia: 3inch makulidwe: 350um ± 25 µm ya Power Electronics

Kufotokozera Kwachidule:

Wafa wa HPSI (High-Purity Silicon Carbide) SiC wokhala ndi mainchesi atatu m'mimba mwake ndi makulidwe a 350 µm ± 25 µm wapangidwa makamaka kuti azigwiritsidwa ntchito zamagetsi zamagetsi zomwe zimafuna zinthu zogwirira ntchito bwino. Wafa wa SiC uwu umapereka mphamvu yoyendetsera kutentha, mphamvu yowononga kwambiri, komanso kugwira ntchito bwino pa kutentha kwakukulu, zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri pakufunika kwakukulu kwa zida zamagetsi zamagetsi zogwiritsa ntchito mphamvu zochepa komanso zolimba. Ma wafa a SiC ndi oyenera kwambiri kugwiritsa ntchito mphamvu zambiri, mphamvu yothamanga kwambiri, komanso nthawi zambiri, pomwe zinthu zogwiritsidwa ntchito za silicon zachikhalidwe sizikwaniritsa zofunikira pa ntchito.
Wafer yathu ya HPSI SiC, yopangidwa pogwiritsa ntchito njira zamakono zotsogola mumakampani, imapezeka m'magawo angapo, iliyonse yopangidwa kuti ikwaniritse zofunikira zinazake zopangira. Wafer iyi imasonyeza kulimba kwa kapangidwe kake, mphamvu zamagetsi, ndi khalidwe la pamwamba, kuonetsetsa kuti ikhoza kupereka magwiridwe antchito odalirika pakugwiritsa ntchito molimbika, kuphatikiza ma semiconductor amagetsi, magalimoto amagetsi (EV), makina amagetsi obwezerezedwanso, ndi kusintha kwa mphamvu zamafakitale.

Kugwiritsa ntchito

Ma wafer a HPSI SiC amagwiritsidwa ntchito m'njira zosiyanasiyana zamagetsi, kuphatikizapo:

Ma semiconductor amphamvu:Ma wafer a SiC amagwiritsidwa ntchito kwambiri popanga ma power diode, ma transistors (MOSFETs, IGBTs), ndi ma thyristors. Ma semiconductor awa amagwiritsidwa ntchito kwambiri pakusintha mphamvu zomwe zimafuna kugwira ntchito bwino komanso kudalirika, monga m'magalimoto amagetsi amakampani, magetsi, ndi ma inverter amagetsi obwezerezedwanso.
Magalimoto Amagetsi (ma EV):Mu magetsi amagetsi a magalimoto, zida zamagetsi zochokera ku SiC zimapereka liwiro losinthira mwachangu, kugwiritsa ntchito mphamvu moyenera, komanso kuchepetsa kutayika kwa kutentha. Zigawo za SiC ndizoyenera kugwiritsidwa ntchito mu machitidwe oyang'anira mabatire (BMS), zomangamanga zochajira, ndi zochajira zomwe zili mkati (OBCs), komwe kuchepetsa kulemera ndikukulitsa kugwiritsa ntchito mphamvu moyenera ndikofunikira.

Machitidwe a Mphamvu Zobwezerezedwanso:Ma wafer a SiC akugwiritsidwa ntchito kwambiri mu ma inverter a dzuwa, ma jenereta a wind turbine, ndi makina osungira mphamvu, komwe kugwira ntchito bwino komanso kulimba ndikofunikira. Zigawo zochokera ku SiC zimathandiza kuti mphamvu zikhale zambiri komanso kuti ntchito izi zigwire bwino ntchito, zomwe zimapangitsa kuti mphamvu zonse zisinthe.

Zamagetsi Zamagetsi Zamakampani:Mu mafakitale ogwira ntchito bwino kwambiri, monga ma motor drive, ma robotic, ndi magetsi akuluakulu, kugwiritsa ntchito ma SiC wafers kumathandiza kuti zinthu ziziyenda bwino, kudalirika, komanso kuyang'anira kutentha. Zipangizo za SiC zimatha kugwira ntchito ndi ma switching frequency okwera komanso kutentha kwambiri, zomwe zimapangitsa kuti zikhale zoyenera malo ovuta.

Malo Olumikizirana ndi Ma Deta:SiC imagwiritsidwa ntchito popanga magetsi pazida zolumikizirana ndi malo osungira deta, komwe kudalirika kwambiri komanso kusintha mphamvu moyenera ndikofunikira. Zipangizo zamagetsi zochokera ku SiC zimathandiza kuti magetsi azigwira ntchito bwino kwambiri pazing'onozing'ono, zomwe zimapangitsa kuti magetsi azigwiritsidwa ntchito pang'ono komanso kuti aziziziritsa bwino m'malo akuluakulu.

Mphamvu yamagetsi yotsika kwambiri, kukana pang'ono, komanso kutentha kwabwino kwa ma wafer a SiC kumapangitsa kuti akhale abwino kwambiri pa ntchito zapamwambazi, zomwe zimathandiza kupanga zida zamagetsi zamagetsi za m'badwo wotsatira zomwe zimagwiritsa ntchito mphamvu moyenera.

Ubwino Waukulu

Kutentha Kwambiri:Ma wafer a SiC amadziwika ndi luso lawo lapadera lochotsa kutentha, zomwe zimathandiza zipangizo zamagetsi kugwira ntchito bwino kwambiri komanso kuthana ndi mafunde amphamvu popanda kutentha kwambiri. Izi ndizofunikira kwambiri pa zamagetsi zamagetsi komwe kuyang'anira kutentha ndi vuto lalikulu.
Kuwonongeka Kwambiri kwa Voliyumu:Kusiyana kwakukulu kwa SiC kumathandiza zipangizo kupirira mphamvu zamagetsi zambiri, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito ndi magetsi amphamvu monga ma gridi amagetsi, magalimoto amagetsi, ndi makina amafakitale.
Kuchita Bwino Kwambiri:Kuphatikiza kwa ma frequency osinthasintha kwambiri komanso kukana pang'ono kumapangitsa kuti zipangizo zikhale ndi mphamvu zochepa, zomwe zimapangitsa kuti mphamvu zisinthe bwino komanso kuchepetsa kufunika kwa makina ozizira ovuta.
Kudalirika M'malo Ovuta:SiC imatha kugwira ntchito kutentha kwambiri (mpaka 600°C), zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'malo omwe angawononge zida zachikhalidwe zopangidwa ndi silicon.
Kusunga Mphamvu:Zipangizo zamagetsi za SiC zimathandiza kuti mphamvu zigwiritsidwe ntchito moyenera, zomwe ndizofunikira kwambiri pochepetsa kugwiritsa ntchito mphamvu, makamaka m'makina akuluakulu monga ma converter amagetsi a mafakitale, magalimoto amagetsi, ndi zomangamanga za mphamvu zongowonjezwdwanso.
