I-Silicon Carbide yezimoto ezintsha ze-Energy

I-Silicon ibilokhu inezinto ezisetshenziswa kakhulu zokwenziwa kwama-semiconductor ama-chip, ikakhulukazi ngenxa ye-Reservance enkulu yeSilicon, izindleko ziphansi, futhi ukulungiswa kulula. Kodwa-ke, ukusetshenziswa kwe-silicon emkhakheni we-opoleelectronics kanye namadivayisi aphezulu aphezulu aphezulu kuyaphazamiseka, futhi ukusebenza kwe-silicon ngamanani aphezulu ampofu, okungafanele izinhlelo zokusebenza eziphezulu ze-voltage. Lokhu kulinganiselwa kwenze kwaba nzima ngokwengeziwe kumadivayisi wamandla ase-silicon ahlangabezana nezidingo zezicelo ezivelayo ezifana nezimoto ezintsha zamandla kanye nesitimela esiphakeme sokusebenza okuphezulu.

Kulesi simo, i-Silicon Carbide ingene endaweni yokubuka. Uma kuqhathaniswa nezinto zokwenziwa zesizukulwane sokuqala nezesibili, i-Sic inochungechunge lwezinto ezinhle kakhulu ze-physicochemical, ngaphezu kobubanzi be-band gap, futhi inezimpawu zensimu ephezulu ye-elektroni, ukuqina okuphezulu kwe-elektroni, ukuthuthuka okuphezulu kwe-elektroni nokuhamba okuphezulu. Inkambu yokuqhekeka kagesi ebucayi i-SIC izikhathi eziyi-10 ukuthi ka-SI kanye nama-5 amahlandla ama-5 e-GAAS, athuthukisa amandla we-GAAS, imvamisa yokusebenza kwamadivayisi we-SIC base, futhi anciphise ukulahleka kwensiza. Kuhlanganiswe nokuvuselelwa okuphezulu okushisayo kune-CU, idivaysi ayidingi amadivaysi angeziwe okushisa okushisa angawasebenzisa, anciphise usayizi womshini ophelele. Ngaphezu kwalokho, amadivaysi e-SIC anokulahleka okuphansi kakhulu futhi angagcina ukusebenza kahle kukagesi emafrikhwe kakhulu e-Ultra-high. Isibonelo, ukuguquka kusuka kusisombululo sezinga ezintathu kususelwa kumadivayisi we-SI kwisixazululo sezinga ezimbili kususelwa ku-SIC kungakhulisa ukusebenza kahle kusuka ku-96% kuya ku-97.6% futhi kunciphise ukusetshenziswa kwamandla nge-40%. Ngakho-ke, amadivaysi e-SIC anezinzuzo ezinhle kakhulu kumandla aphansi, amancane kanye nezinhlelo zokusebenza ezithe xaxa.

Qhathanisa ne-silicon yendabuko, ukusebenza komkhawulo wokusebenzisa i-silicon Carbide kungcono kunalokho kwe-silicon, okungahlangabezana nezidingo zesicelo sokushisa okuphezulu, ingcindezi ephezulu, imvamisa ephezulu, i-silicon Carbide yamanje, kanti i-sarbide ye-silicon yamanje isetshenzisiwe kuyo Amadivayisi we-RF namadivayisi kagesi.

Izinto zokwenziwa ze-silicon carbide zingenza usayizi wedivaysi zincane futhi zincanyana, futhi ukusebenza kungcono futhi kube ngcono, ngakho-ke eminyakeni yamuva nje, abakhiqizi bezimoto zikagesi bakuthandele. Ngokusho kukaRohm, i-5kW LLCDC / DC Converter, iBhodi Yokulawula Amandla yathathelwa indawo yi-silicon carbide esikhundleni samadivayisi we-silicon, isisindo sehliswe kusuka ku-7kg kuya ku-8755cc ku-1350cc. Ubukhulu bedivayisi ye-SIC bungu-1/10 kuphela walokho kwe-silicon device of the aricon okucacisiwe, futhi ukulahleka kwamandla kohlelo lwe-SI Carbit Most kungaphansi kwe-1/4 ye-IGBT esekelwe ku-silicon, engakwazi Letha ukuthuthuka kokusebenza okubalulekile kumkhiqizo wokuphela.
