Embonini yezimoto ehlala ishintsha, kunesidingo esikhulayo semishini esebenza kahle nethembekile.I-STMicroelectronics, umholi womhlaba wonke kwezixazululo ze-semiconductor, ithathe isinyathelo esingajwayelekile sokuhlangabezana nalesi sidingo ngokwandisa iphothifoliyo yayo yemishini ye-automotive silicon carbide (SiC).Ngokuhlanganisa ubuchwepheshe obusezingeni eliphezulu nolwazi lwabo olubanzi kumasekethe ahlanganisiwe ezimoto (ama-IC), i-STMicroelectronics iguqula indlela izimoto ezisebenza ngayo futhi ivula indlela yekusasa elihlanzekile neliphephile.
Ukuqonda Amadivayisi we-SiC
Imishini ye-silicon carbide sekuyisikhathi eside ibhekwa njengenguquko yegeyimu embonini ye-electronics ngenxa yokusebenza kwayo okuphezulu.I-STMicroelectronics iwabonile amandla e-SiC futhi ibihamba phambili ocwaningweni nasekuthuthukisweni kwalobu buchwepheshe.Ngokunwetshwa kwakamuva kwemishini ye-silicon carbide endaweni yezimoto, baqhubeka nokuqinisa ukuzibophezela kwabo ekunikezeni izixazululo ezintsha, ezisebenzayo embonini yezimoto.
Izinzuzo ze-SiC ku-Automotive ICs
Amadivayisi we-SiC anikeza izinzuzo ezimbalwa kumadivayisi wendabuko asekelwe ku-silicon.Ngenxa ye-thermal conductivity enhle kakhulu, amadivaysi e-SiC angasebenza emazingeni okushisa aphezulu, okuwenza alungele izinhlelo zokusebenza zezimoto lapho ukuchithwa kokushisa kubaluleke kakhulu.Ngaphezu kwalokho, amadivayisi we-SiC anokusetshenziswa kwamandla okuphansi kanye nesivinini sokushintsha esiphezulu, ngaleyo ndlela athuthukise ukusebenza kahle kwamandla kanye nokusebenza kohlelo lonke.
Amamojula Amandla kanye nama-MOSFET
Njengengxenye yephothifoliyo yayo yomkhiqizo eyandisiwe, i-STMicroelectronics inikezela ngezinhlobonhlobo zamamojula wamandla we-SiC nama-MOSFET aklanyelwe izinhlelo zokusebenza zezimoto.Kuhlanganiswe nobuchwepheshe bokupakisha obuthuthukisiwe, lawa madivayisi anika amandla ukuminyana kwamandla aphezulu endaweni encane, okuvumela abakhiqizi bezimoto ukuthi bathuthukise ukusetshenziswa kwesikhala futhi bavule amandla aphelele ezimoto zikagesi.
Ama-IC wokuzwa nokulawula
Ukuze unike amandla ukuhlanganiswa okungenamthungo kwamadivayisi we-SiC ku-elekthronikhi yezimoto, i-STMicroelectronics iphinde inikeze ngohlu olubanzi lokuzwa nokulawula ama-IC.Lawa madivaysi aqinisekisa ukulinganisa okunembayo nokuthembekile, ukuqapha nokulawula amasistimu ezimoto ahlukahlukene njengesiteringi samandla, ukubhuleka nokulawula imoto.Ngokusebenzisa ubuchwepheshe be-SiC kulezi zingxenye ezibalulekile, i-STMicroelectronics iphakamisa amazinga okusebenza nokuphepha kwezimoto zesimanje.
Ukushayela uguquko lwemoto kagesi
Njengoba umhlaba uphendukela ezimotweni zikagesi (EVs) ukunciphisa ukukhishwa kwekhabhoni futhi kuliwe nokushintsha kwesimo sezulu, isidingo sama-electronics asebenza kahle siyakhula.Imishini ye-SiC enwetshiwe ye-STMicroelectronics embonini yezimoto idlala indima ebalulekile ekwenzeni lolu shintsho luguqule.Imishini ye-SiC iyakwazi ukuphatha ama-voltage aphezulu nama-currents, ivula indlela yokushaja okusheshayo, ibanga elide lezimoto ezisebenza ngogesi kanye nezinhlelo zokuphatha amandla ezithuthukisiwe.
Ukuthembeka okuthuthukisiwe nokuqina
Enye yezinzuzo ezibalulekile zamadivayisi we-SiC ukuthembeka kwawo okukhethekile nokuqina.Amadivayisi e-SiC angakwazi ukumelana nezimo zokusebenza ezinzima njengamazinga okushisa adlulele kanye nomswakama ophezulu, asebenza kahle kakhulu kunamadivayisi endabuko e-silicon.Lokhu kuqina okuthuthukisiwe kuqinisekisa ukuthi amasistimu ezimoto afakelwe amadivayisi we-STMicroelectronics' SiC agcina ukusebenza okuhle kakhulu kuwo wonke umjikelezo wawo wokuphila, okusiza ukukhulisa impilo yonke yesevisi nokuthembeka kwezimoto zesimanje.
Khulisa ukusebenzisana kwemboni
Ukunwetshwa kwemishini ye-STMicroelectronics 'SiC emkhakheni wezimoto akuyona impumelelo ezimele, kodwa umphumela wokubambisana okuyimpumelelo nabakhiqizi bezimoto, abahlinzeki kanye nezikhungo zocwaningo.Ngokusebenzisana eduze nababambiqhaza ababalulekile bemboni, i-STMicroelectronics ihlale yazi izitayela zakamuva zezimoto, izidingo zamakhasimende kanye nobuchwepheshe obusafufusa ukuze kuqinisekiswe ukuthi amadivayisi ayo e-SiC ahlangabezana ngokugcwele nezidingo eziguqukayo zemakethe yezimoto.
Izinzuzo zemvelo
Ngaphezu kwezinzuzo zabo zobuchwepheshe, amadivayisi we-SiC nawo anikeza izinzuzo ezibalulekile zemvelo.Ngokwenza ngcono ukusebenza kahle kwamandla kanye nokunciphisa ukulahleka kwamandla, amadivayisi we-STMicroelectronics' SiC asiza ukwehlisa ukusetshenziswa kwamandla futhi ehlise i-carbon footprint yemoto.Ngaphezu kwalokho, amadivaysi e-silicon carbide asiza ekuthuthukiseni ingqalasizinda yokushaja izimoto zikagesi, avumele ukushaja ngokushesha futhi akhuthaze ukwamukelwa kwezixazululo ezisimeme zokuhamba.
Amathuba Esikhathi esizayo
Njengoba imboni yezimoto iqhubeka nokuvela, i-STMicroelectronics isalokhu izibophezele ekuqhubekiseni izinto ezintsha kuma-IC wezimoto nokubeka amazinga amasha.Ngephothifoliyo yabo ehlala ikhula yamadivayisi we-SiC, amathuba entuthuko yesikhathi esizayo makhulu.Kusukela ekushayeleni okuzenzakalelayo kuye ezinhlelweni zosizo lwabashayeli (ADAS), amadivayisi e-SiC kulindeleke ukuthi aguqule imboni yezimoto futhi enze izimoto ziphephe, zihlakaniphe, futhi zisimame.
Isiphetho
Ukunwetshwa kwe-STMicroelectronics kumadivayisi e-SiC emkhakheni wezimoto kuphawula ingqopha-mlando ebalulekile embonini yezimoto ye-IC.Ngokusebenzisa izinto eziphakeme ze-silicon carbide, ezinjengokumelana nezinga lokushisa okuphezulu nokulahlekelwa amandla aphansi, i-STMicroelectronics ihola indlela ebheke kwikusasa lezimoto elihlanzekile, eliphephile, nelisebenza ngempumelelo kakhudlwana.Njengoba izimoto ziya ngokuya zifakwa ugesi futhi zisebenza ngokuzenzakalelayo, ukubaluleka kwamadivayisi we-SiC anokwethenjelwa nokusebenza okuphezulu akukwazi ukweqiwa, futhi i-STMicroelectronics ihamba phambili kulolu shintsho.
