Module yo gusharija DC EV ifite ubushobozi bwo hejuru bwa 40kW SiC

Uburyo bwo gusharija bwa SiC bufite ubushobozi bwinshi kuko icyifuzo cyo gusharija vuba cyane kirimo kwiyongera Nyuma y’uko Porsche itangiye gutangaza ku mugaragaro 800V high-voltage platform Taycan muri Nzeri 2019, amasosiyete akomeye ya EV yashyize ahagaragara 800V high-voltage-charging model, nka Hyundai IONIQ, Lotus Eletre, BYD Dolphin, Audi RS e-tron GT, n'izindi. Zose ziratangwa cyangwa zigakorwa ku bwinshi muri iyi myaka ibiri. 800V fast charge iri kuba ikintu gikuru ku isoko; CITIC Securities iteganya ko mu 2025, umubare w’ibikoresho bikoresha ingufu nyinshi (high-voltage charger) uzagera kuri miliyoni 5.18, kandi igipimo cy’injira mu kirere kiziyongera kiva kuri 10% kugeza kuri 34%. Ibi bizaba imbaraga nyamukuru mu iterambere ry’isoko rikoresha ingufu nyinshi, kandi ibigo bikuru byitezwe ko bizabyungukiramo mu buryo butaziguye. Amakuru ya rubanda avuga ko module yo gusharija ari yo gice cy’ingenzi cy’umurundo wo gusharija, ingana na 50% by’ikiguzi cyose cy’umurundo wo gusharija; muri byo, igikoresho cy’amashanyarazi cya semiconductor kingana na 30% by’ikiguzi cya module yo gusharija, ni ukuvuga ko module y’amashanyarazi ya semiconductor ingana na 15% by’ikiguzi cyo gusharija, izaba uruhererekane rw’ingenzi rw’abagenerwabikorwa mu iterambere ry’isoko ry’umurundo wo gusharija. Kugeza ubu, ibikoresho by'amashanyarazi bikoreshwa mu gushyushya ibyuma ni IGBT na MOSFET, byombi bikaba ari ibikoresho bishingiye kuri Si, kandi iterambere ry'ibice byo gushyushya ibyuma kugeza kuri DC byihuse byashyize imbere ibisabwa byinshi ku bikoresho by'amashanyarazi. Kugira ngo imodoka zishyushye vuba nk'uko ziyongera lisansi muri sitasiyo, abakora imodoka barimo gushaka ibikoresho bishobora kunoza imikorere, kandi silicon carbide ni yo iri ku isonga muri iki gihe. Silicon carbide ifite ibyiza byo kudashyushya cyane, kudashyuha cyane, imbaraga nyinshi, nibindi, bishobora kunoza imikorere myiza yo guhindura ingufu no kugabanya ingano y'ibicuruzwa. Imodoka nyinshi zikoresha amashanyarazi zikoresha uburyo bwo gusharija AC buri mu bwato, bugomba gufata amasaha menshi kugira ngo bushyuhe neza. Gukoresha ingufu nyinshi (nk'ingufu za 30kW no hejuru) kugira ngo imodoka zikoresha amashanyarazi zishyuhe vuba byabaye icyerekezo gikurikira cy'ingenzi cyo gusharija ibyuma. Nubwo hari ibyiza byo gukoresha ibyuma bishyushya umuriro bikoresha imbaraga nyinshi, binazana imbogamizi nyinshi, nko: gukenera gukora ibikorwa byo guhindura ibyuma bishyushya umuriro bikoresha imbaraga nyinshi, ndetse n'ubushyuhe buterwa no gutakaza ubushyuhe. Ariko, ibikoresho bya SiC MOSFET na diode bifite imiterere yo kudakoresha amashanyarazi menshi, kudakoresha ubushyuhe bwinshi, no guhindura amashanyarazi vuba, bishobora gukoreshwa neza mu gukoresha ibyuma bishyushya umuriro. Ugereranyije n'ibikoresho bisanzwe bishingiye kuri silicon, ibyuma bishyushya umuriro bya silicon bishobora kongera imbaraga zo gutanga ibyuma bishyushya umuriro hafi ya 30%, no kugabanya igihombo kugeza kuri 50%. Muri icyo gihe, ibikoresho bishyushya umuriro bya silicon nabyo bishobora kongera ubushobozi bwo gushyushya umuriro. Ku bijyanye n'ibice byo gusharija, ikiguzi kiracyari kimwe mu bintu by'ingenzi bibangamira iterambere, bityo ubucucike bw'imbaraga z'ibice byo gusharija ni ingenzi cyane, kandi ibikoresho bya SiC ni ingenzi mu kugera ku bucucike bw'imbaraga nyinshi. Nk'igikoresho gifite voltage nyinshi, umuvuduko mwinshi, kandi gifite ingufu nyinshi, ibikoresho bya silikoni carbide byoroshya imiterere ya DC pile charger module, byongera urwego rw'imbaraga z'igice, kandi byongera cyane ubucucike bw'imbaraga, ibi bikaba bigabanya ikiguzi cya sisitemu cy'ibice byo gusharija. Ukurikije ibiciro n'imikorere myiza y'igihe kirekire, ibyuma bikoresha ingufu nyinshi bikoresha ibikoresho bya SiC bizazana amahirwe menshi ku isoko. Dukurikije amakuru ya CITIC Securities, ubu, igipimo cy’ibikoresho bya silikoni bya karuboni mu miyoboro mishya yo gushyushya imodoka ni hafi 10% gusa, ibi kandi bisiga umwanya munini wo gushyushya imiyoboro ikomeye. Nk'umucuruzi ukomeye mu nganda zitanga amashanyarazi muri DC, MIDA Power yateguye kandi isohora ibicuruzwa bya module yo gushyushya ifite ubucucike bw'ingufu nyinshi, module ya mbere yo gushyushya ku rwego rwo kurinda IP65 ifite ikoranabuhanga ryigenga ry'imiyoboro y'umwuka. Ifite itsinda rikomeye ry'ubushakashatsi n'iterambere n'ihame rigamije isoko, MIDA Power yakoresheje imbaraga nyinshi kandi ikora neza module yo gushyushya ya 40kW SiC ifite ubushobozi bwo hejuru. Ifite ubushobozi butangaje burenze 97% kandi ifite voltage nyinshi cyane kuva kuri 150VDC kugeza kuri 1000VDC, module yo gushyushya ya 40kW SiC yujuje ibisabwa byose ku isi mu gihe izigama ingufu cyane. Bitewe n'ubwiyongere bwihuse bw'umubare w'imirongo yo gushyushya, bikekwa ko SiC MOSFET, na MIDA Power 40kW SiC yo gushyushya izakoreshwa cyane mu mirongo yo gushyushya isaba ubucucike bw'ingufu nyinshi mu gihe kizaza.
