40kW SiC yothandiza kwambiri DC EV Charging Module

SiC yoyendetsa bwino kwambiri yolipiritsa ndiyotheka chifukwa kufunikira kwa ma voltage okwera kwambiri kukukulirakulira Kutsatira chiwonetsero chapadziko lonse cha Porsche cha 800V high-voltage platform model Taycan mu September 2019, makampani akuluakulu a EV atulutsa mitundu yothamanga kwambiri ya 800V, monga Hyundai IONIQ, Lotus Eletre, BYD Dolphin, Audi RS e-tron GT, ndi zina zambiri. Zonse zimaperekedwa kapena zikupangidwa mochuluka m'zaka ziwirizi. Kulipiritsa kwa 800V kukukhala kofala pamsika; CITIC Securities ikuneneratu kuti pofika chaka cha 2025, chiwerengero cha mitundu yothamanga kwambiri chamagetsi chidzafika pa 5.18 miliyoni, ndipo chiwopsezo cholowera chidzawonjezeka kuchokera pakalipano pang'ono kuposa 10% mpaka 34%. Izi zitha kukhala zomwe zimapangitsa kukula kwa msika wothamanga kwambiri wamagetsi, ndipo makampani akumtunda akuyembekezeka kupindula nawo mwachindunji. Malinga ndi chidziwitso cha anthu, gawo lolipiritsa ndilo gawo lalikulu la mulu wolipiritsa, wowerengera pafupifupi 50% ya mtengo wonse wa mulu wolipiritsa; Pakati pawo, chipangizo chamagetsi cha semiconductor chimawerengera 30% ya mtengo wolipiritsa, ndiye kuti, gawo lamphamvu la semiconductor limakhala pafupifupi 15% yamtengo wolipiritsa, lidzakhala lopindula kwambiri pakupanga msika wotsatsa mulu. . Pakadali pano, zida zamagetsi zomwe zimagwiritsidwa ntchito polipira milu ndizo makamaka ma IGBT ndi ma MOSFET, onse omwe ndi zinthu zochokera ku Si, ndipo kupangidwa kwa milu yolipiritsa ku DC kulipiritsa mwachangu kwapereka zofunikira zapamwamba pazida zamagetsi. Kuti azilipiritsa magalimoto mwachangu ngati kupaka mafuta pamalo opangira mafuta, opanga magalimoto akufunafuna mwachangu zida zomwe zingapangitse kuti ntchito ziziyenda bwino, ndipo silicon carbide ndiye mtsogoleri pano. Silicon carbide ili ndi ubwino wokana kutentha kwapamwamba, kukana kuthamanga kwapamwamba, mphamvu zambiri, ndi zina zotero, zomwe zingathe kupititsa patsogolo kutembenuka kwa mphamvu ndikuchepetsa kuchuluka kwa mankhwala. Magalimoto ambiri amagetsi amagwiritsa ntchito njira zolipiritsa za AC, zomwe zimayenera kutenga maola angapo kuti zilipire. Kugwiritsa ntchito mphamvu zambiri (monga 30kW ndi kupitilira apo) kuzindikira kuthamangitsa magalimoto amagetsi kwakhala njira yotsatirira yotsatsira milu. Ngakhale ubwino wokhala ndi milu yothamanga kwambiri, imabweretsanso zovuta zambiri, monga: kufunikira kozindikira ntchito zosinthika zamphamvu kwambiri, komanso kutentha komwe kumabwera chifukwa cha kutayika kwa kutembenuka. Komabe, SiC MOSFET ndi zinthu za diode zili ndi mawonekedwe okana ma voltage apamwamba, kukana kutentha kwambiri, komanso ma frequency osinthika, omwe angagwiritsidwe ntchito bwino pakulipiritsa ma module. Poyerekeza ndi zida zachikhalidwe zozikidwa pa silicon, ma module a silicon carbide amatha kuonjezera mphamvu zolipiritsa milu pafupifupi 30%, ndikuchepetsa kutayika ndi 50%. Nthawi yomweyo, zida za silicon carbide zitha kupangitsanso kukhazikika kwa milu yolipiritsa. Kulipiritsa milu, mtengo ukadali chimodzi mwazinthu zofunika zomwe zimalepheretsa chitukuko, kotero kuchulukitsitsa kwamphamvu kwa milu yolipiritsa ndikofunikira kwambiri, ndipo zida za SiC ndizomwe zimapangitsa kuti pakhale mphamvu zambiri. Monga chipangizo chokwera kwambiri, chothamanga kwambiri, komanso chamakono kwambiri, zida za silicon carbide zimathandizira mawonekedwe ozungulira a DC mulu wacharging module, kuwonjezera mphamvu ya unit, ndikuwonjezera mphamvu yamagetsi, yomwe imatsegula njira yochepetsera mtengo wamtengo wapatali wamtengo wapatali. Potengera mtengo wanthawi yayitali komanso kugwiritsa ntchito moyenera, milu yolipiritsa yamphamvu kwambiri pogwiritsa ntchito zida za SiC idzabweretsa mwayi waukulu wamsika. Malinga ndi data ya CITIC Securities, pakali pano, kulowetsedwa kwa zida za silicon carbide m'milu yatsopano yothamangitsa magalimoto ndi pafupifupi 10%, zomwe zimasiyanso malo ambiri opangira milu yamphamvu kwambiri. Monga ogulitsa otsogola pamakampani opangira ma DC, MIDA Power yapanga ndikutulutsa gawo lolipiritsa lomwe lili ndi mphamvu zambiri, gawo loyamba lachitetezo cha IP65 lokhala ndiukadaulo wodziyimira pawokha. Pokhala ndi gulu lolimba la R&D komanso mfundo yoyang'ana msika, MIDA Power yachita khama ndikukonza moduli ya 40kW SiC yolipiritsa kwambiri. Ndi mphamvu yochititsa chidwi yoposa 97% komanso mphamvu zambiri zolowera kuchokera ku 150VDC kufika ku 1000VDC, gawo la 40kW SiC lacharging limakwaniritsa pafupifupi miyezo yonse yapadziko lonse lapansi pomwe imapulumutsa mphamvu kwambiri. Ndi kukula kwachangu kwa kuchuluka kwa milu yolipiritsa, akukhulupirira kuti ma SiC MOSFETs, ndi MIDA Power 40kW SiC charger module azigwiritsidwa ntchito mobwerezabwereza pakulipiritsa mulu womwe umafunikira mphamvu zambiri zam'tsogolo.
