Ndezvipi shanduko dzichaunzwa nepuratifomu ye800V?

Kana dhizaini yemotokari yemagetsi ikavandudzwa kusvika pa800V, mwero wemidziyo yayo ine voltage yepamusoro ichakwidzwa zvinoenderana, uye inverter ichatsiviwawo kubva pamidziyo yeIGBT yechinyakare kuenda kumidziyo yeMOSFET yeSiC. Mutengo weinverter pachayo unongova wechipiri kubva kumidziyo yebhatiri. Kana ukasimudzira kuenda kuSiC, mutengo uchakwira kusvika padanho rimwe.

Asi kune maOEM, kushandiswa kwesilicon carbide hakungotarise chete mutengo wemidziyo yemagetsi, asi chinonyanya kukosha, shanduko dzemutengo wemotokari yese. Saka, zvakakosha kuwana chiyero pakati pekuchengetedza mari kunounzwa neSiC uye mutengo wayo wepamusoro.
Kana tichitaura nezveSiC, munhu wekutanga kuiedza aive Tesla.

Muna 2018, Tesla yakatsiva mamodule eIGBT nesilicon carbide modules kekutanga muModel 3. Padanho rimwe chete resimba, saizi yepakeji yemamodule esilicon carbide idiki zvakanyanya pane yemamodule esilicon, uye kurasikirwa kwekuchinjana kunoderedzwa ne75%. Uyezve, kana ikachinjwa, kushandisa mamodule eSiC panzvimbo pemamodule eIGBT kunogona kuwedzera kushanda zvakanaka kwesystem ne5%.

Kana tichitarisa mitengo, mutengo wekutsiva wakawedzera neinenge yuan chiuru nemazana mashanu. Zvisinei, nekuda kwekuvandudzwa kwekushanda zvakanaka kwemotokari, simba remabhatiri akaiswa rakaderera, zvichichengetedza mari yebhatiri.
Izvi zvinogona kuonekwa sedambudziko guru kuTesla. Kuwanda kwayo kukuru pamusika kunoderedza mutengo. Tesla yaivimbawo nebhejera iri kuti itore tekinoroji nemusika wemasisitimu emabhatiri e400V.
Panyaya ye800V, Porsche yakatungamira mukupa mota yemitambo yeTaycan ine magetsi ese nesystem ye800V muna 2019, zvichitanga mujaho wezvombo zvekugadzira mota dzemagetsi dze800V dzine magetsi akawanda.
Pane chimwe chinhu "chisina kukodzera" pakuongorora mitengo kubva pamaonero ePorsche. Pamusoro pezvose, inotarisa pamhedzisiro yemotokari dzemhando yepamusoro uye inotarisa pamutengo wepamusoro wemhando.
Asi maererano nekugadzirwa kwetekinoroji uye mashandisirwo ayo, iri ipurojekiti huru inokanganisa muviri wese. Semuenzaniso, pasi pekuchaja kwe800V high-voltage, voltage yebhatiri inofanira kuwedzerwa kusvika ku800V, zvikasadaro ichapiswa nekuda kwekuchaja kwakawanda. Pamusoro pezvo, hazvingosanganisiri system yekuchaja chete, asiwo system yebhatiri, system yemagetsi yekutyaira, zvishandiso zvemagetsi ane simba guru uye system yekubatanidza waya, zvichikanganisa kutanga, kutyaira, kushandiswa kwemhepo inotonhodza mota, nezvimwewo.

Kana muchida kuziva zvakawanda nezveizvi, ndapota musazeza kutibata.
