Pakadali pano, makampani opanga semiconductor akadali panjira yotsika,makampani chipnthawi zambiri akukumana ndi chitsenderezo cha makasitomala odula mitengo ndi kutsika kwamitengo yazinthu, koma IGBT ili munjira ziwiri zazikulu zamagalimoto amagetsi ndi kufunikira kwa solar photovoltaic, kuthamanga kwamisala kwa katundu, kuchepa kwaposachedwa kwakukulu, osati mtengo wokha wakwera sky, makampani sali "kuchuluka kwa mtengo wavuto, koma sangagule" kufotokoza za kuchepa.
IGBT ndi gulu lokhalo la zigawo za semiconductor zomwe zatha kuonjezera mtengo wake ndi kupitirira zomwe zimafunidwa njira yonse, makamaka chifukwa cha kuchepa kwa zinthu panthawiyi, koma kumanga kopenga kwa magetsi a dzuwa, ma inverters awo ali ndi mphamvu zambiri. kufunikira kwa ma IGBT, kuphatikizidwa ndi kufunikira kwakukulu kwa ma IGBT pamagalimoto amagetsi, opanga magalimoto akuluakulu amawadula pafupipafupi.
Akuti IGBT ndi chinthu chosinthira mphamvu, chomwe chimadziwika kuti "power electronics CPU", ndi mphamvu yamagetsi yoyendetsedwa ndi semiconductor yopangidwa ndi BJT (bipolar junction transistor) ndi MOSFET (golide wa oxygen half field effect transistor), ndi zabwino zake. kutsika kwamphamvu kwamagetsi, kupirira kwamphamvu kwambiri komanso kutsika kwamagetsi otsika.
Ndi kukwera kwa magalimoto amagetsi atsopano, kufunikira kwa magetsi okwera kwambiri kwakula kwambiri, ndipo ma IGBT akhala cholinga cha chitukuko cha mafakitale.Chiwerengero cha ma IGBT omwe amagwiritsidwa ntchito m'galimoto yamagetsi ndi okwera kwambiri kuposa mazana, omwe ndi kasanu ndi kawiri mpaka khumi kuposa magalimoto amtundu wamafuta.M'mafakitale, pali ma AC servo motors, ma inverter, magetsi opangidwa ndi mphepo ndi dzuwa ndi magetsi ena obiriwira, ndipo m'gawo lamagetsi okwera, pali njanji zothamanga kwambiri ndi zina zoyendera njanji ndi kugwiritsa ntchito gridi yamagetsi.
Ponena za kugwiritsa ntchitoZithunzi za IGBTm'munda wa dzuwa, ili mu inverter.Monga chipangizo chosinthira mphamvu, inverter imatha kusintha mphamvu yomwe imasungidwa mu solar panel kukhala magetsi omwe amapezeka nthawi zambiri, popanda inverter, makina opangira magetsi sangathe kugwira ntchito ndipo amakhala ndi malo ofunikira pakumanga magetsi adzuwa.
Makampani oyendera dzuwa adanenanso kuti pakuwonjezeka kwa mphamvu zamagetsi zamagetsi zamagetsi, gawo lamphamvu lamagetsi lakhala likuyenda pamsika, ndipo limatha kusintha bwino kubweza kwa oyendetsa magetsi, motero ma inverters ambiri a solar tsopano atumiza IGBT ngati gawo lamagetsi, kufunikira kwayambanso kuyenda bwino.
Kulankhula za yochepa bwanji IGBT?Wapampando wa Moody Ye Zhengxian ananena mosapita m'mbali kuti kuwonjezeka kwa mtengo si chinthu chatsopano, osati vuto la mitengo yamtengo wapatali, koma sangagule, kafukufukuyu adatsimikiza kuti funde la kusowa lidzapitirira kwa kanthawi.
Kuphatikiza apo, malinga ndi chain chain, Hanlei adawonjezera mtengo woyambira wa mzere wopanga wa IGBT ndi pafupifupi 10% koyambirira kwa chaka chino, ndipo pomwe chopangira chopangira chophatikizira chikasinthidwa, Hanlei adawonjezera mtengo motsutsana ndi zomwe zikuchitika, ndikuwunikira momwe msika umakhala wotentha. .
Malinga ndi "2023 Q1 Chip Market Report" yomwe idatulutsidwa ndi Future Electronics pa February 17, 2023, IGBT Q1 ya ST (STMicroelectronics), Microsemi, Infineon, IXYS ndiFairchild(Fairchild Semiconductor), mitundu yayikulu isanu, imakhalabe yofanana ndi nthawi yobereka ya 2022 Q4, pomwe nthawi yobweretsera imakhala yolimba pamasabata 54 motalika kwambiri.
Makamaka, kotala loyamba la 2023, nthawi yotsogolera ya ST's IGBT ndi masabata 47-52, nthawi yotsogolera ya Microsemi's IGBT ndi masabata 42-52, nthawi yotsogolera ya IXYS ya IGBT ndi masabata 50-54, nthawi yotsogolera ya Infineon IGBT ndi masabata 39-50, ndipo Nthawi yotsogolera ya IGBT ya Fairchild ndi masabata 39-52.Komabe, machitidwe otumizira komanso mitengo yamitundu yayikulu 5yi ndi yokhazikika, yopanda kukwera.
Kusanthula kwamakampani, pali zifukwa ziwiri zazikulu za kuchepa kwakukulu kwa ma IGBT, choyamba ndi gawo lapano la ma inverters a solar omwe amagwiritsa ntchito ma IGBT awonjezeka kwambiri.Chachiwiri ndi chakuti makampani opangira semiconductor pakali pano ali mu nthawi yokonzekera, osati mphamvu yokhayokha, komanso mphamvu zambiri zachotsedwa ndi mafakitale amagetsi amagetsi, zomwe zimapangitsa kuti pakhale kusowa kwakukulu kwa IGBTs pansi pa zotsatira zowonongeka.
