Emkhakheni wezinto zokwakha ze-semiconductor, i-silicon carbide (SiC) iqhamuke njengekhandidethi elithembisayo esizukulwaneni esilandelayo sama-semiconductors asebenza kahle futhi anobungani imvelo. Ngezakhiwo zayo eziyingqayizivele namandla ayo, ama-silicon carbide semiconductors avula indlela yekusasa elisimeme nelisebenza kahle kakhudlwana.
I-Silicon carbide iyi-semiconductor ehlanganisiwe eyakhiwe i-silicon ne-carbon. Inezici ezinhle kakhulu eziyenza ilungele ukusetshenziswa ezinhlobonhlobo zemishini kagesi. Enye yezinzuzo eziyinhloko zama-semiconductors e-SiC yikhono lokusebenza emazingeni okushisa aphezulu kanye nama-voltage uma kuqhathaniswa nama-semiconductors asekelwe ku-silicon. Leli khono livumela ukuthuthukiswa kwezinhlelo ze-elekthronikhi ezinamandla kakhulu nezithembekile, okwenza i-SiC ibe yinto ekhangayo kakhulu yama-electronics wamandla kanye nezicelo zokushisa okuphezulu.
Izakhiwo ezinobungani bemvelo zama-silicon carbide semiconductors
Ngaphezu kokusebenza kwezinga lokushisa eliphezulu,i-silicon carbide semiconductorsfuthi inikeza izinzuzo ezibalulekile zemvelo. Ngokungafani nama-semiconductors e-silicon yendabuko, i-SiC ine-carbon footprint encane futhi isebenzisa amandla amancane ngesikhathi sokukhiqiza. Izakhiwo ze-SiC ezinobungani kwemvelo zikwenza kube ukukhetha okuhle ezinkampanini ezifuna ukunciphisa umthelela wemvelo ngenkathi zigcina ukusebenza okuphezulu.
Kuboniswa ngezici ezilandelayo:
Ukusetshenziswa kwamandla nokusebenza kahle kwezinsiza:
I-silicon carbide semiconductor inokuhamba kwe-electron ephakeme kanye nokumelana nesiteshi okuphansi, ngakho-ke ingakwazi ukuzuza ukusebenza kahle kokusetshenziswa kwamandla ngokusebenza okufanayo. Lokhu kusho ukuthi ukusebenzisa i-silicon carbide kumadivayisi we-semiconductor kunganciphisa ukusetshenziswa kwamandla futhi kunciphise ukusetshenziswa kwezinsiza.
Impilo ende nokuthembeka:
Sic semiconductorinokuqina okuphezulu kokushisa kanye nokumelana nemisebe, ngakho-ke isebenza kangcono ekushiseni okuphezulu, amandla aphezulu, nasezindaweni eziphakeme zemisebe, yandisa impilo yesevisi nokuthembeka kwemishini kagesi. Lokhu kusho ingcindezi encane yemvelo ngenxa ye-e-waste.
Ukonga amandla kanye nokuncishiswa kokukhipha umoya:
Ukusetshenziswa kwe-silicon carbide semiconductors kungathuthukisa ukusebenza kahle kwamandla kwemishini kagesi futhi kunciphise ukusetshenziswa kwamandla. Ikakhulukazi emikhakheni efana nezimoto zikagesi kanye nokukhanyisa kwe-LED, izinhlelo zokusebenza ze-silicon carbide semiconductor zinganciphisa kakhulu ukusetshenziswa kwamandla kanye nokukhishwa kwegesi.
Ukugaywa kabusha:
Ama-semiconductors e-silicon carbide anokuqina okuphezulu kokushisa nokuqina, ngakho-ke angakwazi ukuphinda asetshenziswe ngokuphumelelayo ngemva kokuphela kwempilo yemishini, okunciphisa umthelela omubi wemfucuza endaweni ezungezile.
Ngaphezu kwalokho, ukusetshenziswa kwama-semiconductors e-silicon carbide kungaholela ezinhlelweni zikagesi ezonga amandla, ezingasiza ekunciphiseni ukusetshenziswa kwamandla okuphelele kanye nokukhishwa kwegesi ebamba ukushisa. Amandla e-SiC okufaka isandla ekusaseni eliluhlaza, elisimeme kakhudlwana kuwumthombo oyinhloko wokuthakasela okukhulayo kulokhu kwaziswa kwe-semiconductor.
Indima ye-silicon carbide semiconductors ekwenzeni ngcono ukusebenza kahle kwamandla
Emkhakheni wezamandla,I-silicon carbide-based power electronics ingathuthukisa iziguquli zamandla ezisebenza kahle kakhulu futhi ezihlangene zezinhlelo zamandla avuselelekayo njengamapulazi elanga nawomoya. Lokhu kungakhuphula ukusebenza kahle kokuguqulwa kwamandla futhi kunciphise izindleko zesistimu zizonke, kwenze amandla avuselelekayo aqhudelane kakhudlwana nezibaseli zendabuko zemvelo.
Izimoto zikagesi (EVs) ne-hybrid electric vehicles (HEVs) zingazuza ekusebenziseni ugesi wamandla we-SiC, okuvumela ukushaja okusheshayo, ibanga lokushayela isikhathi eside nokusebenza okuthuthukisiwe kukonke kwemoto. Ngokushayela ukwamukelwa okusabalele kwezinto zokuhamba zikagesi, ama-silicon carbide semiconductors angasiza ekunciphiseni ukukhishwa kwegesi ebamba ukushisa embonini yezimoto kanye nokuthembela kumafutha ezinto ezimbiwa phansi.
Izindaba zempumelelo yemboni ye-Silicon carbide semiconductor
Emkhakheni wamandla, i-silicon carbide-based power electronics isetshenziswe kuma-inverters axhunywe kugridi yezinhlelo ze-solar photovoltaic, ngaleyo ndlela andise ukusebenza kahle kokuguqulwa kwamandla nokuthuthukisa ukwethembeka kwesistimu. Lokhu kukhuthaza ukukhula okuqhubekayo kwamandla elanga njengomthombo wamandla ahlanzekile futhi osimeme.
Embonini yezokuthutha, ama-semiconductors e-silicon carbide ahlanganiswe ezinhlelweni ze-powertrain zezimoto zikagesi kanye ne-hybrid, okwenza ngcono ukusebenza kwemoto kanye nebanga lokushayela.
