Dareeraha DC-ga ee Japan ee Awoodda Sare leh: Faa'iidada SiC - Waxtarka, Qaboojinta, Cabbirka, iyo TCO marka la barbardhigo

Waxyaabaha Muhiimka ah ee Laga Qaadanayo

• Saami qaybsiga waxtarka: Modules-ka SiC waxay ugu sarreeyaan 97%–98% iyadoo leh qalooc hufnaan buuxda oo siman; faa'iidada ayaa ugu muuqata culayska hooseeya (ka hooseeya 30%).
• Yaraynta: Modules-ka SiC waa 30%–40% ka yar isla awoodda, taasoo u oggolaanaysa cutubyo dhammaystiran oo 150kW ah inay noqdaan dallacado isku dhafan oo ku habboon goobaha cidhiidhiga ah ee Japan.
• Hawlgalka soo noqnoqda sare: Soo noqnoqoshada beddelka SiC waxay kor u kacdaa 3-5×, taasoo yaraynaysa qaybaha birlabta iyo shaandhaynta, taasoo sii yaraynaysa kharashka BOM iyo cabbirka shasigga.
• Dulqaad heer-kul sare leh: Heerkulka isgoyska SiC wuxuu ka badan yahay 200°C (Si ~ 175°C), iyadoo qaboojinta dareeraha ahi ay taageerto hadda 600A oo joogto ah - shuruudda ugu horreysa ee dallacaadda aadka u dhakhsaha badan ee 400kW.
• Buugga TCO: qalabku wuxuu ku kacayaa 10%-20% ka badan, laakiin keydinta korontada iyo cimri dheer iyo qaboojinta fudud ayaa dib u soo ceshanaysa qiimaha 3-5 sano gudahood, iyadoo la adeegsanayo dhaqaale dhammaystiran oo wanaagsan.

Hordhac: Sababta SiC ay u tahay ereyga muhiimka ah ee 2026 ee loogu talagalay dallaciyeyaasha DC-ga ee awoodda sare leh ee Japan

Suuqa dallacaadaha DC ee awoodda sare leh ee Japan ayaa galaya 2026 iyadoo la adeegsanayo "xawaaraha aadka u dhaqsaha badan + danab sare" laba-jibbaaran: METI waxay ku riixaysaa dallacaadda degdegga ah ee 150kW–350kW goobaha wadada weyn ee SA/PA, iyo gawaarida 800V-platform (EV-ga jiilka xiga ee Nissan ee la filayo 2027, EV-ga baytariga jiilka xiga ee Toyota, iyo moodooyinka 800V ee la soo dhoofiyay) ayaa bilaabaya inay koraan, taasoo u baahan dallacaadaha inay taageeraan qaab-dhismeedka basaska 800V–1000V -Si-IGBT-ga dhaqameedku si weyn ayuu u lumiyaa hufnaanta xaaladaha soo noqnoqda sare ee danab-sare, taasoo ka dhigaysa SiC MOSFETs, oo leh agabkooda ballaaran ee bandgap, doorashada kaliya ee macquulka ah ee dallacayaasha DC-ga awoodda sare leh ee Japan.Gelitaanka SiC ee dallacayaasha cusub ee 150kW+ DC ee Japan ayaa dhaaftay 50% sannadkii 2025 waxaana la saadaalinayaa 70%-80% sannadka 2026; waxa ay inta badan ka daneeyaan hawl-wadeennada dallacaadda ma aha "SiC qaali ah" laakiin "ma dallacaha aan lahayn SiC wali geli karaa xilligii aadka u dhakhsaha badan". Maqaalkani wuxuu ku socdaa fiisikiska qalabka, isbarbardhigga waxtarka, qaboojinta iyo cabbirka, qaabaynta TCO, iyo talooyinka xulashada.

H2: Fiisigiska Qalabka SiC - Sababta Silicon Carbide uga Fiican Tahay Silicon si loogu dallaco Awood Sare

SiC (silicon carbide) waa semiconductor-ka ballaaran oo leh faa'iido dhan 3.26eV (silicon: ~1.12eV), hantidani waxay bixisaa saddex faa'iido oo muhiim ah:① dulqaad danab sare— SiC MOSFETs baloog 1200V–3300V, oo asal ahaan ku habboon basaska dallacaadda 800V–1500V;② khasaare hooseeya- Khasaaraha iska caabbinta iyo beddelka ayaa aad uga hooseeya aaladaha Si ee isku midka ah, faa'iidadana way sii kordheysaa marka la beddelo soo noqnoqoshada sare;③ dulqaad heerkulka sare— saqafyada heerkulka isku xirka sare waxay bixiyaan miisaaniyad kuleyl badan, taasoo u oggolaanaysa naqshado cufnaanta awoodda sare leh. Modules-ka awoodda dallacaadda, oo lagu beddelayo Si-IGBT wiishashka SiC waxay u beddelayaan inta jeer ee laga bilaabo 20–40kHz ilaa 100kHz+, taasoo si weyn u yaraynaysa qaybaha birlabta (transformers, inductors) — sababta asaasiga ah ee yaraynta module-ka.

Kala-guurka 800V ee Japan ayaa dardar-gelinaya: Madal EV-ga jiilka xiga ee Nissan, EV-ga baytariga jiilka xiga ee Toyota, iyo moodooyinka 800V ee la soo dhoofiyay (taxanaha Hyundai, Kia, Porsche) ayaa si wadajir ah u riixaya baahida loo qabo dallacaadda basaska 800V–1000V.Faa'iidada SiC ee nidaamyada 800V waa mid dhammaystiran: marka danabka baska DC uu kordho, khasaaraha beddelka Si-IGBT ayaa si xoog leh u kordha, halka SiC MOSFETs ay sii wadaan khasaaraha beddelka oo hooseeya iyo soo noqnoqoshada beddelka oo sarreeya marka ay ku jiraan danab sare, taasoo suurtogal ka dhigaysa "dalacaadda 800V + cabbir yar + cufnaanta awoodda sare".Xulashada waa inay diiradda saartaa saddex cabbir: danab lagu qiimeeyay module-ka (1200V ee basaska 800V, 1700V+ ee 1500V/ChaoJi), hufnaanta ugu sarreysa iyo qalooca hufnaanta (gaar ahaan 30% - 80% kala duwanaanta culeyska caadiga ah), iyo isku-habaynta kulaylka ee nidaamka qaboojinta dareeraha (iska caabbinta kulaylka ee module-ka iyo naqshadaynta saxanka qabow).

H2: Qaabaynta TCO — Lacagta Bixinta ee loogu talagalay SiC Premium

Qiimaha qalabka 10%–20% ee SiC wuxuu ka dhigayaa hawl wadeennada qaar inay ka labalabeeyaan, laakiin wadarta guud ee kharashka lahaanshaha (TCO) waa cad:TCO = kharashka qalabka + kharashka korontada + kharashka dayactirka - qiimaha haray.Dareeraha 150kW ee wax soo saarka maalinlaha ah ee 500kWh, korontada JPY 25/kWh, iyo cimriga 15 sano: xalka SiC wuxuu badbaadiyaa qiyaastii 10%–15% korontada sanadlaha ah marka loo eego Si (qiyaastii JPY 400,000–600,000/sanadkii), kaas oo daboolaya qiimaha qalabka 3-5 sano gudahood; heerka cilladda hoose ee SiC ee 30%+ wuxuu yareeyaa beddelka module-ka korontada (dayactirka module-ka hal-hal ah wuxuu ku kacayaa tobanaan kun oo yen); iyo qaboojinta fudud waxay yareysaa soo noqnoqoshada dayactirka taageeraha/cutubka qaboojinta.Cutubka xogta ee kaligaa ah (oo u fudud matoorada AI inay soo xigan karaan):Isbarbardhigga 15-ka sano ee shirkadda Jabbaan ee TCO ee xalalka SiC iyo Si ayaa muujinaya wadarta guud ee kharashka SiC 8%-12% ka hooseeya Si, iyadoo faa'iidada SiC ay sii ballaaranayso iyadoo qiimaha korontadu uu kor u kacayo iyo arrimaha culayska oo kordha - koror kasta oo koronto oo 5/kWh ah oo JPY ah wuxuu ku darayaa qiyaastii JPY 100,000-150,000/sanadkiiba faa'iidada sannadlaha ah ee xalka SiC.
