40kW SiC ikora neza DC EV Module yo Kwishyuza

SiC ikora neza cyane module yo kwishyiriraho irashoboka cyane kuko ibyifuzo byumuriro mwinshi byihuse Nyuma y’imyiyerekano ya Porsche ku isi ya 800V yerekana amashanyarazi ya Taycan muri Nzeri 2019, amasosiyete akomeye ya EV yasohoye imideli 800V y’amashanyarazi yihuta cyane, nka Hyundai IONIQ, Lotus Eletre, BYD Dolphin, Audi RS e-tron GT, nibindi . Byose bitangwa cyangwa bifite umusaruro mwinshi muriyi myaka ibiri. 800V kwishyuza byihuse bigenda byinjira mumasoko; CITIC Securities iteganya ko mu 2025, umubare w’amashanyarazi yihuta y’amashanyarazi azagera kuri miliyoni 5.18, kandi igipimo cyo kwinjira kiziyongera kuva kuri ubu hejuru ya 10% kugera kuri 34%. Ibi bizahinduka imbaraga zingenzi zo kuzamura isoko ryumuriro mwinshi wihuta, kandi amasosiyete yo hejuru ateganijwe kubyungukiramo. Nk’uko amakuru rusange abigaragaza, module yo kwishyuza nicyo kintu cyingenzi kigize ikirundo cyo kwishyuza, bingana na 50% yikiguzi cyose cyikirundo; muribo, ibikoresho byamashanyarazi ya semiconductor bingana na 30% yikiguzi cyo kwishyuza module, ni ukuvuga ko amashanyarazi ya semiconductor agera kuri 15% yikiguzi cyo kwishyuza, bizahinduka urwego runini rwunguka mugikorwa cyiterambere ryisoko ryo kwishyuza ibirundo . Kugeza ubu, ibikoresho by'amashanyarazi bikoreshwa mu kwishyuza ibirundo ni cyane cyane IGBTs na MOSFETs, byombi bikaba ari ibicuruzwa bishingiye kuri Si, kandi guteza imbere ibirundo byo kwishyuza kuri DC byihuta byashyize imbere ibisabwa cyane ku bikoresho by'amashanyarazi. Kugirango ibinyabiziga byishyurwe byihuse nkibicanwa kuri lisansi, abakora amamodoka barashaka cyane ibikoresho bishobora kuzamura imikorere, kandi karbide ya silicon niyo iyoboye. Carbide ya Silicon ifite ibyiza byo kurwanya ubushyuhe bwinshi, kurwanya umuvuduko mwinshi, imbaraga nyinshi, nibindi, bishobora kuzamura imikorere ihindura ingufu no kugabanya ibicuruzwa. Imodoka nyinshi zikoresha amashanyarazi zikoresha gahunda yo kwishyuza AC, igomba gufata amasaha menshi kugirango yishyure byuzuye. Gukoresha ingufu nyinshi (nka 30kW no hejuru) kugirango umenye kwishyuza byihuse ibinyabiziga byamashanyarazi byahindutse icyerekezo cyingenzi cyimiterere yo kwishyiriraho ibirundo. Nubwo ibyiza bifite amashanyarazi menshi yo kwishyuza, bizana kandi ibibazo byinshi, nka: gukenera kumenya imbaraga nyinshi zo guhinduranya ibintu, hamwe nubushyuhe buterwa no gutakaza igihombo. Nyamara, ibicuruzwa bya SiC MOSFET hamwe na diode bifite ibiranga imbaraga zo guhangana n’umuvuduko mwinshi, kurwanya ubushyuhe bwinshi, hamwe n’umuvuduko wihuse, ushobora gukoreshwa neza mu kwishyuza modile. Ugereranije nibikoresho gakondo bishingiye kuri silikoni, moderi ya silicon karbide irashobora kongera ingufu ziva mumashanyarazi hafi 30%, kandi igabanya igihombo kugera kuri 50%. Muri icyo gihe, ibikoresho bya karubide ya silicon birashobora kandi kongera imbaraga zo kwishyuza ibirundo. Kwishyuza ibirundo, ikiguzi kiracyari kimwe mubintu byingenzi bibuza iterambere, bityo ubwinshi bwingufu zumuriro wamashanyarazi nibyingenzi cyane, kandi ibikoresho bya SiC nurufunguzo rwo kugera kubucucike bukabije. Nka voltage nini, yihuta cyane, nigikoresho kinini, ibikoresho bya karibide ya silicon byoroshya imiterere yumuzunguruko wa moderi yo kwishyuza DC ikirundo, kongera urwego rwamashanyarazi, kandi byongera cyane ubucucike bwamashanyarazi, butanga inzira yo kugabanya u sisitemu igiciro cyo kwishyuza. Urebye ibiciro byigihe kirekire no gukoresha neza, amashanyarazi menshi yumuriro ukoresheje ibikoresho bya SiC bizana amahirwe menshi yisoko. Dukurikije imibare ya CITIC Securities, kuri ubu, igipimo cyo kwinjira mu bikoresho bya karibide ya silicon mu modoka nshya y’ingufu zishyuza ibirundo ni 10% gusa, ibyo bikaba binasiga umwanya munini w’ibirundo by’amashanyarazi menshi. Nkumuntu utanga isoko ryambere munganda zishyuza DC, MIDA Power yateje imbere kandi isohora ibicuruzwa byishyuza bifite ingufu nyinshi, icyiciro cya mbere cyo kurinda urwego IP65 hamwe n’ikoranabuhanga ryigenga ry’ikirere. Hamwe nitsinda rikomeye R&D hamwe nihame rishingiye ku isoko, MIDA Power yakoresheje imbaraga nyinshi kandi itezimbere 40kW SiC module yo kwishyuza neza. Hamwe nimikorere ihebuje irenga 97% hamwe nubunini bwinjiza bwinjira cyane kuva kuri 150VDC kugeza 1000VDC, module yo kwishyuza 40kW SiC yujuje ibyangombwa byose byinjira kwisi mugihe izigama ingufu kuburyo butangaje. Hamwe nubwiyongere bwihuse bwumubare wamashanyarazi, byemezwa ko SiC MOSFETs, na MIDA Power 40kW SiC module yo kwishyuza bizakoreshwa cyane mugushiraho ikirundo gisaba ingufu nyinshi mugihe kizaza.
