Tlhaloso e Khutšoanyane:

The HPSI (High-Purity Silicon Carbide) SiC wafer, e bophara ba 3-inch le botenya ba 350 µm ± 25 µm, e entsoe bakeng sa lisebelisoa tsa motlakase tsa morao-rao. Li-wafers tsa SiC li tsebahala ka thepa ea tsona e ikhethang, joalo ka mocheso o phahameng oa mocheso, ho hanyetsa motlakase o phahameng, le tahlehelo e fokolang ea matla, e leng se etsang hore e be khetho e ratoang bakeng sa lisebelisoa tsa semiconductor ea matla. Li-wafers tsena li etselitsoe ho sebetsana le maemo a feteletseng, tse fanang ka ts'ebetso e ntlafetseng libakeng tse phahameng, tse nang le motlakase o phahameng, le maemo a mocheso o phahameng, kaofela ha tsona li netefatsa ho sebetsa hantle ha matla le ho tšoarella nako e telele.

Li-wafers tsa HPSI SiC li bohlokoa ho nolofatseng lisebelisoa tsa motlakase tsa moloko o latelang, tse sebelisoang mefuteng e fapaneng ea ts'ebetso e phahameng:
Sistimi ea Phetoho ea Matla: Li-wafers tsa SiC li sebetsa e le lisebelisoa tsa mantlha bakeng sa lisebelisoa tsa motlakase tse joalo ka li-MOSFET tsa matla, diode, le li-IGBT, tse bohlokoa bakeng sa phetolo ea matla e sebetsang lipotolohong tsa motlakase. Likarolo tsena li fumaneha lisebelisoa tsa motlakase tse sebetsang hantle haholo, li-drive tsa makoloi le li-inverters tsa indasteri.

Likoloi tsa Motlakase (EVs):Tlhokahalo e ntseng e eketseha ea likoloi tsa motlakase e hloka hore ho sebelisoe lisebelisoa tsa elektroniki tse sebetsang hantle, 'me li-wafer tsa SiC li ka pele ho phetoho ena. Ho li-powertrains tsa EV, li-wafers tsena li fana ka ts'ebetso e phahameng le bokhoni ba ho chencha kapele, bo kenyang letsoho ho nako ea ho tjhaja kapele, sebaka se selelele, le ts'ebetso e ntlafalitsoeng ea koloi ka kakaretso.

Matla a Tsosolositsoeng:Litsamaisong tsa matla tse nchafalitsoeng joalo ka matla a letsatsi le a moea, li-wafers tsa SiC li sebelisoa ho li-inverters le li-converter tse nolofalletsang ho hapa le ho ajoa ha matla haholoanyane. The high conductivity thermal conductivity and superior breakdown voltage of SiC etsa bonnete ba hore litsamaiso tsena li sebetsa ka botšepehi, esita le tlas'a maemo a feteletseng a tikoloho.

Indasteri ea Boiketsetso le Liroboto:Lisebelisoa tsa motlakase tse sebetsang hantle haholo lits'ebetsong tsa liindasteri le liroboto li hloka lisebelisoa tse khonang ho fetoha kapele, ho sebetsana le meroalo e meholo ea matla, le ho sebetsa tlasa khatello e matla. Li-semiconductors tse thehiloeng ho SiC li fihlela litlhoko tsena ka ho fana ka ts'ebetso e phahameng le matla, esita le maemong a thata a ts'ebetso.

Mecha ea puisano:Mehahong ea likhokahano tsa mehala, moo ho ts'eptjoang haholo le phetolo ea matla e sebetsang hantle, li-wafers tsa SiC li sebelisoa phepelong ea motlakase le li-converter tsa DC-DC. Lisebelisoa tsa SiC li thusa ho fokotsa tšebeliso ea matla le ho ntlafatsa ts'ebetso ea sistimi litsing tsa data le marang-rang a puisano.

Ka ho fana ka motheo o tiileng bakeng sa likopo tsa matla a phahameng, sephaphatha sa HPSI SiC se nolofalletsa nts'etsopele ea lisebelisoa tse bolokang matla, ho thusa liindasteri ho fetela ho litharollo tse tala, tse tsitsitseng haholoanyane.
