Kugwiritsa ntchito
Ma wafer a HPSI SiC ndi ofunikira kwambiri poyambitsa zida zamagetsi za m'badwo wotsatira, zomwe zimagwiritsidwa ntchito m'njira zosiyanasiyana zogwirira ntchito bwino:
Machitidwe Osinthira Mphamvu: Ma wafer a SiC amagwiritsidwa ntchito ngati zinthu zofunika kwambiri pazida zamagetsi monga ma MOSFET amphamvu, ma diode, ndi ma IGBT, zomwe ndizofunikira kwambiri pakusintha mphamvu bwino m'mabwalo amagetsi. Zigawozi zimapezeka mumagetsi amphamvu kwambiri, ma mota, ndi ma inverter amafakitale.
Magalimoto Amagetsi (ma EV):Kufunika kwakukulu kwa magalimoto amagetsi kumafuna kugwiritsa ntchito magetsi amphamvu kwambiri, ndipo ma wafer a SiC ali patsogolo pa kusinthaku. Mu ma electrotrain amagetsi, ma wafer awa amapereka mphamvu zambiri komanso kusinthana mwachangu, zomwe zimathandiza kuti nthawi yochaja ichepe mwachangu, ikhale yayitali, komanso kuti magalimoto azigwira bwino ntchito.
Mphamvu Zongowonjezedwanso:Mu makina ogwiritsira ntchito mphamvu zongowonjezwdwa monga mphamvu ya dzuwa ndi mphepo, ma wafer a SiC amagwiritsidwa ntchito mu ma inverter ndi ma converter omwe amalola kuti mphamvu zigwire bwino ntchito komanso kugawidwa bwino. Kuchuluka kwa kutentha ndi mphamvu ya SiC yotsika kwambiri kumatsimikizira kuti makinawa amagwira ntchito modalirika, ngakhale pansi pa nyengo yovuta kwambiri.
Makina Odzipangira Okha ndi Ma Robotic:Zipangizo zamagetsi zamagetsi zogwira ntchito bwino kwambiri m'makina odziyimira pawokha a mafakitale ndi maloboti zimafuna zida zomwe zimatha kusintha mwachangu, kuthana ndi katundu wambiri wamagetsi, komanso kugwira ntchito movutikira kwambiri. Ma semiconductor okhala ndi SiC amakwaniritsa zofunikira izi popereka magwiridwe antchito apamwamba komanso olimba, ngakhale m'malo ovuta ogwirira ntchito.
Machitidwe Olumikizirana:Mu zomangamanga zamatelefoni, komwe kudalirika kwambiri komanso kusintha mphamvu moyenera ndikofunikira kwambiri, ma wafer a SiC amagwiritsidwa ntchito mumagetsi ndi ma converter a DC-DC. Zipangizo za SiC zimathandiza kuchepetsa kugwiritsa ntchito mphamvu ndikuwonjezera magwiridwe antchito a makina m'malo osungira deta ndi ma network olumikizirana.
Mwa kupereka maziko olimba a ntchito zamagetsi amphamvu kwambiri, HPSI SiC wafer imathandiza kupanga zipangizo zogwiritsa ntchito mphamvu moyenera, kuthandiza mafakitale kusintha kukhala njira zobiriwira komanso zokhazikika.

Ubwino Waukulu
Kugwira Ntchito Kwambiri kwa Kutentha: Kuthamanga kwa kutentha kwa SiC kumatsimikizira kuti kutentha kumataya bwino muzipangizo zamagetsi, zomwe zimawathandiza kuti azigwira ntchito pamlingo wapamwamba komanso pafupipafupi popanda kutentha kwambiri. Izi zikutanthauza kuti makina ang'onoang'ono, ogwira ntchito bwino komanso nthawi yayitali yogwira ntchito.
Volti Yowonongeka Kwambiri: Ndi bandgap yayikulu poyerekeza ndi silicon, ma wafer a SiC amathandizira kugwiritsa ntchito ma voltage apamwamba, zomwe zimapangitsa kuti akhale abwino kwambiri pazinthu zamagetsi zamagetsi zomwe zimafunikira kupirira ma voltage okwera kwambiri, monga magalimoto amagetsi, makina amagetsi a gridi, ndi makina amagetsi obwezerezedwanso.
Kuchepa kwa Mphamvu: Kuchepa kwa mphamvu zomwe zimagwiritsidwa ntchito komanso kuthamanga kwachangu kwa zida za SiC kumapangitsa kuti mphamvu zichepe panthawi yogwira ntchito. Izi sizimangowonjezera mphamvu zokha komanso zimawonjezera ndalama zomwe zimagwiritsidwa ntchito posungira mphamvu zonse m'makina omwe zimagwiritsidwa ntchito.
Kudalirika Kwambiri M'malo Ovuta: Kapangidwe kake kolimba ka zinthu za SiC kamathandiza kuti igwire ntchito bwino kwambiri, monga kutentha kwambiri (mpaka 600°C), magetsi amphamvu, komanso ma frequency apamwamba. Izi zimapangitsa ma wafer a SiC kukhala oyenera kugwiritsidwa ntchito m'mafakitale, m'magalimoto, komanso m'magetsi.
Kugwiritsa Ntchito Mphamvu Moyenera: Zipangizo za SiC zimapereka mphamvu zambiri kuposa zipangizo zachikhalidwe zopangidwa ndi silicon, zomwe zimachepetsa kukula ndi kulemera kwa makina amagetsi amphamvu pomwe zikuwonjezera magwiridwe antchito awo onse. Izi zimapangitsa kuti pakhale ndalama zochepa komanso kuchepetsa kuwonongeka kwa chilengedwe pakugwiritsa ntchito mphamvu zongowonjezwdwanso ndi magalimoto amagetsi.
Kukula: Kukula kwa mainchesi atatu m'mimba mwake komanso kulekerera kolondola kwa kupanga kwa wafer ya HPSI SiC kumatsimikizira kuti ikhoza kukulitsidwa popanga zinthu zambiri, kukwaniritsa zofunikira zonse za kafukufuku komanso zamalonda.
Mapeto
Wafer ya HPSI SiC, yokhala ndi mainchesi 3 m'mimba mwake ndi makulidwe a 350 µm ± 25 µm, ndi chinthu chabwino kwambiri pa zipangizo zamagetsi zamagetsi zomwe zimagwira ntchito bwino kwambiri. Kuphatikiza kwake kwapadera kwa kutentha, magetsi owonongeka kwambiri, kutayika kwa mphamvu zochepa, komanso kudalirika pamikhalidwe yovuta kwambiri kumapangitsa kuti ikhale gawo lofunikira kwambiri pakugwiritsa ntchito mphamvu zosiyanasiyana, mphamvu zongowonjezwdwanso, magalimoto amagetsi, machitidwe amafakitale, ndi kulumikizana kwa mafoni.
Wafer iyi ya SiC ndi yoyenera kwambiri m'mafakitale omwe akufuna kupeza magwiridwe antchito apamwamba, kusunga mphamvu zambiri, komanso kudalirika kwa makina. Pamene ukadaulo wa zamagetsi ukupitilira kusintha, wafer ya HPSI SiC imapereka maziko oti pakhale njira zatsopano zogwiritsira ntchito mphamvu moyenera, zomwe zimapangitsa kuti pakhale tsogolo lokhazikika komanso lopanda mpweya wambiri.
