Kupita patsogolo mu Ukadaulo wa IGBT Rectifier Kukulimbikitsa Kukula Kwabwino Kwambiri mu Gawo Latsopano la Mphamvu

M'zaka zaposachedwapa, chifukwa cha kukwera kwa dziko lonse lapansi kwa carbon neutrality, makampani atsopano amagetsi—makamaka m'madera monga photovoltaics, mabatire, hydrogen electrolysis, ndi malo osungira mphamvu—akula kwambiri. Izi zabweretsa kufunikira kwakukulu kwaukadaulo wa zida zamagetsi, ndipo ma rectifiers oyendetsedwa ndi IGBT (Insulated Gate Bipolar Transistor) akuwoneka ngati gawo lofunikira kwambiri pakugwiritsa ntchito zinthu zofunika kwambiri.

Poyerekeza ndi ma rectifier achikhalidwe a SCR (Silicon Controlled Rectifier), ma rectifier a IGBT amapereka zabwino zazikulu monga kugwira ntchito pafupipafupi, kutulutsa kochepa kwambiri, kuyankha mwachangu, komanso kuwongolera molondola. Zinthu izi zimapangitsa kuti zikhale zoyenera kwambiri pakugwiritsa ntchito komwe kumafuna kukhazikika kwamphamvu kwamphamvu komanso kusintha mwachangu - zomwe zimapezeka kwambiri m'malo atsopano amagetsi.

Mwachitsanzo, mu gawo la mphamvu ya haidrojeni, makina amagetsi amadzi amafuna "mphamvu yamagetsi yapamwamba, mphamvu yamagetsi yapamwamba, komanso mphamvu yokhazikika yotulutsa." Ma rectifier a IGBT amapereka mphamvu yolondola yowongolera mphamvu yamagetsi yosasinthasintha, kupewa mavuto monga kutentha kwambiri kwa ma electrode ndi kuchepa kwa mphamvu yamagetsi. Yankho lawo labwino kwambiri lamphamvu limathandizanso kuti azitha kusintha momwe zinthu zimakhalira ndi mphamvu yamagetsi yosinthasintha kwambiri.

Mofananamo, m'makina osungira mphamvu ndi zida zoyesera batire, ma IGBT rectifiers amasonyeza kuwongolera bwino kayendedwe ka mphamvu m'mbali zonse ziwiri. Amatha kusinthana mosavuta pakati pa njira zochajira ndi zotulutsira mphamvu, zomwe zimapangitsa kuti mphamvu zizigwira bwino ntchito komanso kudalirika kwa makina.

Malinga ndi malipoti a makampani, pofika chaka cha 2030, gawo la msika wa ma IGBT rectifiers mu gawo latsopano la mphamvu likuyembekezeka kuwirikiza kawiri—makamaka m'magawo apakati mpaka okwera kwambiri amagetsi (monga 800V ndi kupitirira apo), komwe kufunikira kukukula mofulumira.

Pakadali pano, opanga magetsi ambiri m'dziko muno komanso padziko lonse lapansi akuyang'ana kwambiri pa zatsopano zokhudzana ndi IGBT. Ntchitozi zikuphatikizapo kukonza ma driver circuits, kupititsa patsogolo magwiridwe antchito a ma module cooling, komanso kupanga njira zowongolera zanzeru kwambiri kuti zipereke magetsi ogwira ntchito bwino, anzeru, komanso odalirika.

Pamene ukadaulo watsopano wamagetsi ukupitilirabe kusintha, zokonzanso za IGBT sizimangowonetsa kupita patsogolo kwaukadaulo komanso zikuyembekezeka kuchita gawo lofunikira pakusintha kwa mphamvu ndi kupititsa patsogolo luntha la mafakitale.
