HPSI SiC wafer dia:3inch botenya:350um± 25 µm bakeng sa Power Electronics

Tlhaloso e Khutšoanyane:

Sephaphatha sa HPSI (High-Purity Silicon Carbide) SiC se bophara ba lisenthimithara tse 3 le botenya ba 350 µm ± 25 µm se etselitsoe ka ho khetheha lisebelisoa tsa motlakase tsa motlakase tse hlokang li-substrate tse sebetsang hantle. Sephaphatha sena sa SiC se fana ka conductivity e phahameng ea mocheso, matla a phahameng a ho senyeha, le bokhoni bo phahameng ba mocheso o sebetsang, e leng se etsang hore e be khetho e nepahetseng bakeng sa tlhokahalo e ntseng e eketseha ea lisebelisoa tsa elektroniki tse sebetsang hantle le tse matla. Li-wafers tsa SiC li loketse ka ho khetheha bakeng sa lisebelisoa tse phahameng tsa motlakase, tsa morao-rao, le tsa maqhubu a phahameng, moo likaroloana tsa silicon tsa setso li hlōlehang ho finyella litlhoko tsa ts'ebetso.
Sephaphatha sa rona sa HPSI SiC, se entsoeng ka ho sebelisa mekhoa ea morao-rao e etellang pele indastering, se fumaneha ka limaraka tse 'maloa, e' ngoe le e 'ngoe e etselitsoe ho fihlela litlhoko tse khethehileng tsa tlhahiso. Wafer e bonts'a bots'epehi bo ikhethang ba sebopeho, thepa ea motlakase, le boleng ba bokaholimo, ho netefatsa hore e ka fana ka ts'ebetso e ts'epahalang lits'ebetsong tse batloang, ho kenyeletsoa li-semiconductors tsa motlakase, likoloi tsa motlakase (EVs), lisebelisoa tse nchafalitsoeng tsa matla le phetolo ea matla a indasteri.

Li-wafers tsa HPSI SiC li sebelisoa mefuteng e mengata ea lisebelisoa tsa elektroniki, ho kenyelletsa:

Li-Semiconductors tsa Matla:Li-wafers tsa SiC hangata li sebelisoa ho hlahisa li-diode tsa matla, li-transistors (MOSFETs, IGBTs), le thyristors. Li-semiconductors tsena li sebelisoa haholo lits'ebetsong tsa phetolo ea matla tse hlokang ts'ebetso e phahameng le ts'epahalo, joalo ka li-drive tsa liindasteri, lisebelisoa tsa motlakase le li-inverters bakeng sa lits'ebetso tsa matla a ka nchafatsoang.
Likoloi tsa Motlakase (EVs):Likarolong tsa motlakase tsa likoloi tsa motlakase, lisebelisoa tsa motlakase tse thehiloeng ho SiC li fana ka lebelo la ho fetoha ka potlako, matla a phahameng a matla, le tahlehelo e fokotsehileng ea mocheso. Likarolo tsa SiC li loketse lits'ebetso tsa lits'ebetso tsa taolo ea betri (BMS), lits'ebetso tsa ho tjhaja, le li-charger tsa on-board (OBCs), moo ho fokotsa boima ba 'mele le ho eketsa ts'ebetso e nepahetseng ea ho fetola matla ho bohlokoa.

Sistimi ea Matla a Tsosolositsoeng:Li-wafers tsa SiC li ntse li sebelisoa haholo ho li-inverters tsa letsatsi, lijenereithara tsa turbine tsa moea, le lits'ebetso tsa polokelo ea matla, moo ts'ebetso e phahameng le matla a hlokahalang. Likarolo tse thehiloeng ho SiC li thusa matla a phahameng a matla le ts'ebetso e ntlafetseng lits'ebetsong tsena, ho ntlafatsa katleho ea ho fetola matla ka kakaretso.

Lisebelisoa tsa SiC li khona ho sebetsana le maqhubu a phahameng a ho feto-fetoha le mocheso o phahameng, li etsa hore li tšoanelehe bakeng sa maemo a boima.

Litsi tsa Mehala le Boitsebiso:SiC e sebelisoa phepelong ea motlakase bakeng sa lisebelisoa tsa mehala ea mehala le litsi tsa data, moo ho ts'eptjoang haholo le phetoho e sebetsang ea matla e leng bohlokoa. Lisebelisoa tsa motlakase tse thehiloeng ho SiC li etsa hore ho be le ts'ebetso e phahameng ka boholo bo nyane, e fetolelang tšebeliso e fokotsehileng ea matla le ts'ebetso e ntle ea ho pholisa lits'ebetsong tse kholo.
