Silicon carbide yeMotokari dzeSimba Dzitsva Dzinotarisirwa

Silishon yagara ichishandiswa zvakanyanya kugadzirwa kweiyo Semiconductor Chips, kunyanya nekuda kweiyo hombe yekuchengetedza silicon, mutengo wakaderera, uye kugadzirira kwacho kuri nyore. Nekudaro, kushandiswa kweSilicon mumunda weOptoyelectronics uye yakakwirira-frequency mhandu-masimba masimba emasikisheni pane zvakakwirira midziyo, iyo haina kukodzera kune zvakakwirira-voltage zvinyorwa. Aya macomputer akaita kuti zviwedzere kuomesesa silicon-based mashandiro emidziyo yekusaita zvido zvekubuda senge mota nyowani uye yakakwirira-yekumhanyisa njanji uye yakakwirira-frequency performance.

Mundima iyi, silicon carbide yapinda mune yakajeka. Kuenzaniswa neyekutanga uye yechipiri yechizvarwa zvinhu zvezvinyorwa zvakanaka zvechiremba, zvine hungwaru hwemagetsi emagetsi emagetsi, yakakwira lecron velocity, yakakwirira yekudzora maitiro, yakakwirira emagetsi emagetsi gensity uye kufamba kwakanyanya. Iyo yakanyanya kuputsa leaddric shamba yeSIC ndeye kagumi iyo yeSIC uye 5 times iyo yeGaas, inoshanda frequency, uye inodzora midziyo yeSIC yekubvisa, uye inoderedza kurasikirwa kweiyo mudziyo. Yakabatanidzwa neyekunyama inobata Uye zvakare, SIC zvishandiso zvine yakaderera inoderera kurasikirwa uye inogona kuchengetedza yakanaka yemagetsi kuita paIltra-yakakwira marefu. Semuenzaniso, kuchinja kubva kune matatu-mwero mhinduro zvichienderana nemidziyo yemaviri kune maviri-mwero mhinduro zvichienderana neSIC inogona kuwedzera kubva pa99% kusvika 97.6% uye kuderedza masimba ekushandisa kusvika pa40%. Naizvozvo, zvishandiso zveSIC zvine zvakanakira zvakakura zvakaderera-simba, miniaturized uye yakakwirira-frequency application.

Zvichienzaniswa neSildon Silicon, shanduro yekushandisa yetilicon carbide iri nani pane iyo yeSilicon yekushisa, yakakwirira yekudzvinyirira yekushisa Zano reRF uye mashandiro esimba.

Silicon carbide zvinhu zvinogona kuita kuti saizi yemushini idiki uye idiki, uye kuita kuri kuita zviri nani uye zviri nani, saka mumakore mashoma, vagadziri vemagetsi vakafarira. Sekureva kwaRohm, A 5KW LLCDC / DC Converter, Dc Converter Bhodhi Rekushanduka Saizi yeSIC Chishandiso Chete 1/10 yeiyo yeSilicon Chishandiso cheSefitidziro, uye kurasikirwa kwesimba kweiyo SI Carbit System iri pasi pe1 / 4 yeiyo ILICON-based Igbt, iyo inogona zvakare Huya nekukakavara kwakakosha kuita kune chigadzirwa chekupedzisira.

Silicon carbide yave imwezve application nyowani mune ceramic substrate yetsva esimba motokari .
