40kW SiC oo ah DC EV oo hufnaan sare leh

Module-ka dallacaadda waxtarka sare leh ee SiC waa mid aad u awood badan maadaama baahida loo qabo dallacaadda degdegga ah ee korantada sare ay kor u kacayso Ka dib markii Porsche ay soo bandhigtay moodeelka madal koronto-sare ee 800V ee Taycan bishii Sebtembar 2019, shirkadaha waaweyn ee EV waxay soo saareen moodooyinka koronto-sare ee 800V ee degdega ah, sida Hyundai IONIQ, Lotus Eletre, BYD Dolphin, Audi RS e-tron GT, iwm. Dhammaantood waa la keenay ama waxay leeyihiin wax soo saar ballaaran labadan sano gudahood. Ku dallacaadda degdegga ah ee 800V ayaa noqonaysa tan ugu weyn suuqa; CITIC Securities waxay saadaalineysaa in marka la gaaro 2025, tirada moodooyinka dallacaadda degdegga ah ee danab sare leh ay gaari doonaan 5.18 milyan, heerka gelitaankana uu ka kordhi doono hadda wax yar oo ka badan 10% ilaa 34%. Tani waxay noqon doontaa xoogga ugu muhiimsan ee kobaca suuqa dallacaadda degdegga ah ee danab sare leh, shirkadaha kor u kacana waxaa la filayaa inay si toos ah uga faa'iidaystaan. Sida laga soo xigtay macluumaadka dadweynaha, qaybta dallacaadda waa qaybta ugu muhiimsan ee qaybta dallacaadda, taasoo ka dhigan qiyaastii 50% wadarta kharashka qaybta dallacaadda; iyaga ka mid ah, qalabka korontada semiconductor wuxuu ka dhigan yahay 30% kharashka qaybta dallacaadda, taas oo ah, qaybta korontada semiconductor waxay ka dhigan tahay qiyaastii 15% kharashka qaybta dallacaadda, waxayna noqon doontaa silsiladda ka faa'iideystaha ugu weyn ee geeddi-socodka horumarinta suuqa qaybta dallacaadda. Waqtigan xaadirka ah, aaladaha korontada ee loo isticmaalo tuulmooyinka dallacaadda badanaa waa IGBTs iyo MOSFETs, labaduba waa badeecooyin ku salaysan Si, horumarinta tuulmooyinka dallacaadda ee DC-ga dallacaadda degdegga ah waxay soo bandhigtay shuruudo sare oo loogu talagalay aaladaha korontada. Si looga dhigo dallacaadda baabuurta mid dhakhso badan sida shidaal ka saarista saldhigga shidaalka, shirkadaha baabuurta sameeya ayaa si firfircoon u raadinaya agab hagaajin kara hufnaanta, carbide-ka silicon-na hadda waa hoggaamiyaha. Carbide-ka Silicon wuxuu leeyahay faa'iidooyinka iska caabbinta heerkulka sare, iska caabbinta cadaadiska sare, awoodda sare, iwm., taas oo hagaajin karta hufnaanta beddelka tamarta iyo yareynta mugga badeecada. Baabuurta korontada ku shaqeeya badankood waxay isticmaalaan nidaamyada dallacaadda AC-ga ee saaran, kuwaas oo ay tahay inay qaataan dhowr saacadood si ay si buuxda u dallacaan. Isticmaalka awoodda sare (sida 30kW iyo wixii ka sarreeya) si loo xaqiijiyo dallacaadda degdegga ah ee baabuurta korontada ku shaqeeya ayaa noqotay jihada muhiimka ah ee xigta ee qaabaynta dallacaadda. Iyadoo ay jirto faa'iidooyinka ay leedahay tuulmooyinka dallacaadda awoodda sare leh, waxay sidoo kale keentaa caqabado badan, sida: baahida loo qabo in la xaqiijiyo hawlgallada beddelashada soo noqnoqoshada sare leh ee awoodda sare leh, iyo kulaylka ay keento khasaaraha beddelaadda. Si kastaba ha ahaatee, alaabada SiC MOSFET iyo diode waxay leeyihiin astaamaha iska caabbinta danab sare leh, iska caabbinta heerkulka sare leh, iyo soo noqnoqoshada wareejinta degdega ah, taas oo si fiican loogu isticmaali karo modules-ka dallacaadda. Marka la barbardhigo aaladaha dhaqameed ee ku salaysan silicon, modules-ka carbide-ka silicon waxay kordhin karaan awoodda wax soo saarka ee tuulmooyinka dallacaadda ku dhawaad ​​30%, waxayna yareyn karaan khasaaraha ilaa 50%. Isla mar ahaantaana, aaladaha carbide-ka silicon waxay sidoo kale kor u qaadi karaan xasilloonida tuulmooyinka dallacaadda. Tuubooyinka dallacaadda, kharashku wali waa mid ka mid ah arrimaha muhiimka ah ee xaddidaya horumarka, sidaa darteed cufnaanta awoodda ee tuulmooyinka dallacaadda waa mid aad muhiim u ah, aaladaha SiC-na waa furaha lagu gaaro cufnaanta awoodda sare. Maadaama ay yihiin qalab koronto sare leh, xawaare sare leh, iyo qalab koronto sare leh, aaladaha carbide-ka silicon-ka ayaa fududeeya qaab-dhismeedka wareegga ee module-ka dallacaadda tuulmada DC, waxay kordhiyaan heerka awoodda cutubka, waxayna si weyn u kordhiyaan cufnaanta awoodda, taas oo u gogol xaaraysa yaraynta kharashka nidaamka ee tuulmada dallacaadda. Marka laga eego dhinaca kharashka muddada dheer iyo hufnaanta isticmaalka, tiirarka dallacaadda awoodda sare leh ee isticmaalaya aaladaha SiC waxay keeni doonaan fursado suuq oo aad u weyn. Sida laga soo xigtay xogta CITIC Securities, hadda, heerka gelitaanka aaladaha carbide-ka silicon ee ku jira tuulmooyinka cusub ee dallacaadda baabuurta tamarta leh waa qiyaastii 10% oo keliya, taas oo sidoo kale ka dhigaysa meel ballaaran oo loogu talagalay tuulmooyinka dallacaadda awoodda sare leh. Iyada oo ah alaab-qeybiye hormuud ka ah warshadaha dallacaadda DC, MIDA Power waxay soo saartay oo ay soo saartay badeecadda module-ka dallacaadda oo leh cufnaanta awoodda ugu sarreysa, module-ka dallacaadda heerka ilaalinta IP65 ee ugu horreeya oo leh tignoolajiyada marinnada hawada ee madaxbannaan. Iyada oo leh koox cilmi-baaris iyo horumarin xooggan iyo mabda'a suuqa ku salaysan, MIDA Power waxay dadaal badan gelisay waxayna si guul leh u horumarisay module-ka dallacaadda hufnaanta sare ee 40kW SiC. Iyada oo leh hufnaan heer sare ah oo ka badan 97% iyo kala duwanaansho koronto oo aad u ballaaran oo laga bilaabo 150VDC ilaa 1000VDC, module-ka dallacaadda 40kW SiC wuxuu buuxiyaa ku dhawaad ​​​​dhammaan heerarka gelinta adduunka iyadoo si weyn u badbaadinaysa tamarta. Iyadoo kororka degdegga ah ee tirada dallacaadaha dallacaadda, waxaa la rumeysan yahay in module-ka dallacaadda SiC MOSFETs, iyo MIDA Power 40kW SiC loo isticmaali doono si aad iyo aad ah loogu isticmaalo tuubada dallacaadda ee u baahan cufnaanta awoodda sare mustaqbalka.
