HPSI SiC wafer dia: 3inch thickness: 350um ± 25 µm yePower Electronics

Tsananguro pfupi:

Wafer yeHPSI (High-Purity Silicon Carbide) SiC ine dhayamita yemainji matatu uye ukobvu hwe350 µm ± 25 µm yakagadzirirwa zvakananga mashandisirwo emagetsi emagetsi anoda ma substrate anoshanda zvakanyanya. Iyi wafer yeSiC inopa conductivity yepamusoro yekupisa, voltage yakanyanya kupwanyika, uye kushanda zvakanaka pakupisa kwakanyanya, zvichiita kuti ive sarudzo yakakodzera kudiwa kuri kukura kwemidziyo yemagetsi inoshanda nesimba uye yakasimba. Mawafer eSiC anonyanya kukodzera mashandisirwo emagetsi ane voltage yakawanda, high-current, uye high-frequency, uko ma substrate echinyakare esilicon asingakwanise kusangana nezvinodiwa zvekushanda.
Wafer yedu yeHPSI SiC, yakagadzirwa uchishandisa matekiniki matsva anotungamira muindasitiri, inowanikwa mumhando dzakasiyana-siyana, imwe neimwe yakagadzirirwa kusangana nezvinodiwa zvekugadzira. Wafer iyi inoratidza kunaka kwechimiro, hunhu hwemagetsi, uye kunaka kwepamusoro, zvichiita kuti ikwanise kupa mashandiro akavimbika mukushandiswa kwakasimba, kusanganisira ma semiconductor emagetsi, mota dzemagetsi (EV), masisitimu esimba rinogona kudzokororwa, uye kushandurwa kwesimba remaindasitiri.

Kushandiswa

Mawafer eHPSI SiC anoshandiswa mumhando dzakasiyana dzemagetsi emagetsi, kusanganisira:

MaSemiconductor eSimba:Mawafer eSiC anowanzo shandiswa mukugadzira ma power diodes, transistors (MOSFETs, IGBTs), uye thyristors. Ma semiconductor aya anoshandiswa zvakanyanya mukushandiswa kwesimba rinoda kushanda nesimba uye kuvimbika, senge muma industrial motor drives, magetsi, uye ma inverters emagetsi anodzokororwa.
Mota dzemagetsi (mota dzemagetsi):Mumagetsi emotokari dzemagetsi, zvishandiso zvemagetsi zvinobva kuSiC zvinopa kumhanya kwekuchinja nekukurumidza, kushanda nesimba kwakanyanya, uye kurasikirwa nekupisa kushoma. Zvikamu zveSiC zvakanakira kushandiswa mumasisitimu ekugadzirisa mabhatiri (BMS), zvivakwa zvekuchaja, uye machaja ari mubhodhi (OBCs), uko kuderedza huremu uye kuwedzera kushanda kwesimba rekushandura simba kwakakosha.

Masisitimu Esimba Rinodzokororwa:Mawafer eSiC ari kushandiswa zvakanyanya muma solar inverters, ma wind turbine generators, uye masisitimu ekuchengetera simba, uko kushanda nesimba kwakanyanya uye kusimba kwakakosha. Zvikamu zveSiC zvinogonesa kuwanda kwesimba uye kushanda kwakawedzerwa mumashandisirwo aya, zvichivandudza kushanda kwese kwekushandura simba.

Magetsi Emagetsi Emaindasitiri:Mumaindasitiri anoshanda zvakanyanya, akadai semamotor drives, marobhoti, uye magetsi makuru, kushandiswa kwemaSiC wafers kunobvumira kushanda kwakanaka maererano nekushanda zvakanaka, kuvimbika, uye kutonga kwekupisa. Midziyo yeSiC inogona kubata ma frequency ekuchinja akakwira uye tembiricha yakakwira, zvichiita kuti ive yakakodzera nharaunda dzinoda simba.

Nzvimbo dzekukurukurirana nedata:SiC inoshandiswa mumagetsi ekushandisa michina yekutaurirana nenzvimbo dzedata, uko kuvimbika kwakanyanya uye kushandurwa kwesimba zvinobudirira kwakakosha. Midziyo yemagetsi yakavakirwa paSiC inoita kuti pave nekushanda kwakasimba pahukuru hudiki, izvo zvinoita kuti kushandiswa kwesimba kuderedzwa uye kutonhora kushande zviri nani muzvivakwa zvikuru.

Kukanganiswa kwakanyanya kwemagetsi, kusapindirana kwakaderera, uye kufambiswa kwakanaka kwemafuta eSiC wafers zvinoita kuti zvive zvinhu zvakanakisisa zvekushandisa izvi zvepamusoro, zvichigonesa kugadzirwa kwemagetsi emagetsi echizvarwa chinotevera asingashandise simba zvakanyanya.

Mabhenefiti Akakosha

Kufambisa Kwekupisa Kwakanyanya:Mawafer eSiC anozivikanwa nekugona kwawo kubvisa kupisa, izvo zvinoita kuti michina yemagetsi ishande zvakanaka uye ikwanise kubata magetsi akawandisa pasina kupisa zvakanyanya. Chinhu ichi chakakosha mumagetsi emagetsi uko kutonga kupisa kuri dambudziko guru.
Kuparara Kwemagetsi Kwakanyanya:Kusashanda zvakanaka kweSiC kunoita kuti michina ikwanise kushivirira magetsi akawandisa, zvichiita kuti ive yakakodzera kushandiswa kwemagetsi ane simba guru akadai semagetsi, mota dzemagetsi, uye michina yemumaindasitiri.
Kushanda Nesimba Kwakanyanya:Kusanganiswa kwema frequency ekuchinja-chinja zvakanyanya uye kusadzivirira magetsi zvakanyanya kunoita kuti michina iwane simba shoma, zvichivandudza kushanda zvakanaka kwesimba uye zvichideredza kudiwa kwemasystem ekutonhodza akaomarara.
Kuvimbika Munzvimbo Dzine Hukasha:SiC inokwanisa kushanda pakupisa kwakanyanya (kusvika 600°C), izvo zvinoita kuti ikodzere kushandiswa munzvimbo dzaizokanganisa michina yechinyakare yakagadzirwa nesilicon.
Kuchengetedza Simba:Midziyo yemagetsi yeSiC inovandudza mashandiro ekushandura simba, izvo zvakakosha mukuderedza kushandiswa kwesimba, kunyanya mumasisitimu makuru akadai semaindasitiri anochinja simba, mota dzemagetsi, uye zvivakwa zvesimba rinogona kuvandudzwa.
