Mtengo wamagetsi osungira mphamvu umapangidwa makamaka ndi mabatire ndi ma inverters osungira mphamvu. Zonse ziwirizi zimapanga 80% ya mtengo wamagetsi osungira mphamvu zamagetsi, zomwe inverter yosungirako mphamvu imakhala 20%. IGBT insulating grid bipolar crystal ndiye zinthu zakumtunda za inverter yosungirako mphamvu. Kuchita kwa IGBT kumatsimikizira magwiridwe antchito a inverter yosungirako mphamvu, kuwerengera 20% -30% ya mtengo wa inverter.
Udindo waukulu wa IGBT m'malo osungira mphamvu ndi thiransifoma, kutembenuka pafupipafupi, kutembenuka kwapakati, ndi zina zambiri, chomwe ndi chida chofunikira kwambiri pakusungira mphamvu.
Chithunzi: IGBT module
Kumtunda kwa zipangizo zosungiramo mphamvu zosungirako mphamvu kumaphatikizapo IGBT, capacitance, kukana, kukana magetsi, PCB, ndi zina zotero. Pakati pawo, IGBT akadali makamaka zimadalira kunja. Padakali kusiyana pakati pa IGBT yapakhomo pamlingo waukadaulo ndi otsogola padziko lonse lapansi. Komabe, ndikukula kwachangu kwamakampani osungira mphamvu ku China, njira yopangira nyumba za IGBT ikuyembekezekanso kufulumira.
Mtengo wa IGBT wosungira mphamvu
Poyerekeza ndi photovoltaic, mtengo wa IGBT yosungirako mphamvu ndi wapamwamba kwambiri. Kusungirako mphamvu kumagwiritsa ntchito IGBT ndi SIC zambiri, zomwe zimaphatikizapo maulalo awiri: DCDC ndi DCAC, kuphatikizapo mayankho awiri, omwe ndi optical storage Integrated ndi osiyana mphamvu yosungirako mphamvu. Dongosolo lodziyimira palokha losungirako mphamvu, kuchuluka kwa zida zamagetsi za semiconductor kuli pafupifupi nthawi 1.5 kuposa photovoltaic. Pakalipano, kusungirako kuwala kumatha kuwerengera zoposa 60-70%, ndipo njira yosungiramo mphamvu yosiyana ndi 30%.

IGBT ili ndi magawo osiyanasiyana ogwiritsira ntchito, omwe ndi opindulitsa kwambiri kuposa MOSFET mu inverter yosungirako mphamvu. M'mapulojekiti enieni, IGBT yasintha pang'onopang'ono MOSFET monga chida chachikulu cha ma inverters a photovoltaic ndi kupanga magetsi a mphepo. Kukula mwachangu kwamakampani opanga mphamvu zatsopano kudzakhala mphamvu yatsopano yoyendetsera makampani a IGBT.
IGBT ndiye chida chachikulu chosinthira mphamvu ndikufalitsa
IGBT ikhoza kumveka bwino ngati transistor yomwe imayendetsa magetsi awiri -njira (multi-directional) ikuyenda ndi ma valve control.
IGBT ndi chipangizo chophatikizika chathunthu - control voltage -driven power semiconductor chida chopangidwa ndi BJT bipolar triode ndi insulating grid field effect chubu. Ubwino wa mbali ziwiri za kutsika kwamphamvu.

Ntchito yosinthira ya IGBT ndikupanga njira powonjezera zabwino pamagetsi amagetsi kuti apereke maziko apano ku PNP transistor kuyendetsa IGBT. Mosiyana ndi izi, onjezani magetsi olowera pakhomo kuti muchotse tchanelo, yendani m'malo obwerera kumbuyo, ndikuzimitsa IGBT. Njira yoyendetsera IGBT ndiyofanana ndi ya MOSFET. Imangofunika kuwongolera mlongoti wa N one -channel MOSFET, chifukwa chake ili ndi mawonekedwe apamwamba olowera.
IGBT ndiye chida chachikulu chosinthira mphamvu ndikufalitsa. Amadziwika kuti "CPU" ya zida zamagetsi zamagetsi. Monga dziko strategic akutuluka makampani, wakhala chimagwiritsidwa ntchito zida zatsopano mphamvu ndi madera ena.
IGBT ili ndi maubwino ambiri kuphatikiza kulowetsedwa kwakukulu, mphamvu yocheperako, kuwongolera kosavuta, kuthamanga kwachangu, kuthamanga kwanthawi yayitali, kuthamanga kwapang'onopang'ono, komanso kutaya pang'ono. Chifukwa chake, ili ndi zabwino zonse pamsika wapano.
Chifukwa chake, IGBT yakhala yotchuka kwambiri pamsika wamagetsi wamagetsi wamakono. Amagwiritsidwa ntchito kwambiri m'madera ambiri monga mphamvu zatsopano zamagetsi, magalimoto amagetsi ndi milu yolipiritsa, zombo zamagetsi, kutumiza kwa DC, kusungirako mphamvu, kulamulira magetsi a mafakitale ndi kupulumutsa mphamvu.
Chithunzi:InfineonGawo la IGBT
Gulu la IGBT
Malinga ndi kapangidwe kazinthu zosiyanasiyana, IGBT ili ndi mitundu itatu: chitoliro chimodzi, gawo la IGBT ndi gawo lamphamvu lamphamvu IPM.
(Kulipiritsa milu) ndi magawo ena (makamaka zinthu zomwe zimagulitsidwa pamsika wapano). The wanzeru mphamvu gawo IPM makamaka chimagwiritsidwa ntchito m'munda wa zipangizo woyera kunyumba monga inverter air conditioners ndi pafupipafupi kutembenuka makina ochapira.
Kutengera mphamvu yamagetsi akugwiritsa ntchito, IGBT ili ndi mitundu monga ultra -low voltage, low voltage, medium voltage and high voltage.
Pakati pawo, IGBT yogwiritsidwa ntchito ndi magalimoto amagetsi atsopano, kuyang'anira mafakitale, ndi zipangizo zapakhomo zimakhala ndi magetsi apakati, pamene maulendo a njanji, magetsi opangira magetsi atsopano ndi ma grids anzeru ali ndi zofunikira zowonjezera magetsi, makamaka pogwiritsa ntchito high -voltage IGBT.
IGBT nthawi zambiri imawoneka ngati ma module. Deta ya IHS imasonyeza kuti chiwerengero cha ma modules ndi chubu limodzi ndi 3: 1. Gawoli ndi mankhwala opangira semiconductor opangidwa ndi chipangizo cha IGBT ndi FWD (chipwirikiti cha diode chip) kupyolera mu mlatho wozungulira, komanso kupyolera mu mafelemu apulasitiki, magawo ndi magawo. , ndi zina.
