Izindleko zesistimu yokugcina amandla zakhiwe ikakhulukazi amabhethri nama-inverters okugcina amandla. Isamba salokhu kokubili sihlanganisa ama-80% ezindleko zohlelo lokugcina amandla e-electrochemical, lapho inverter yokugcina amandla yenza ama-20%. I-IGBT insulating grid bipolar crystal iyimpahla eluhlaza ekhuphukayo ye-inverter yokugcina amandla. Ukusebenza kwe-IGBT kunquma ukusebenza kwe-inverter yokugcina amandla, ibalwa ku-20% -30% yenani le-inverter.
Indima eyinhloko ye-IGBT emkhakheni wokugcinwa kwamandla i-transformer, ukuguqulwa kwemvamisa, ukuguqulwa kwe-intervolution, njll., okuyithuluzi elibalulekile ekusetshenzisweni kokugcina amandla.
Umfanekiso: Imojula ye-IGBT
Izinto zokusetshenziswa ezikhuphukayo zokuguquguquka kokugcinwa kwamandla zifaka i-IGBT, amandla, ukumelana, ukumelana nogesi, i-PCB, njll. Phakathi kwazo, i-IGBT isancike kakhulu ekuthengisweni kwamanye amazwe. Kusenegebe phakathi kwe-IGBT yasekhaya ezingeni lobuchwepheshe kanye nezinga elihamba phambili emhlabeni. Kodwa-ke, ngokuthuthuka okusheshayo kwemboni yaseChina yokugcina amandla, inqubo yokwenziwa kwasekhaya kwe-IGBT kulindeleke ukuthi isheshise.
Inani lesicelo sesitoreji samandla se-IGBT
Uma kuqhathaniswa ne-photovoltaic, inani le-IGBT yokugcina amandla liphezulu kakhulu. Isitoreji samandla sisebenzisa i-IGBT ne-SIC eyengeziwe, ehlanganisa izixhumanisi ezimbili: i-DCDC ne-DCAC, okuhlanganisa izixazululo ezimbili, okuyisistimu yokugcina amandla ehlanganisiwe nehlukene. Uhlelo oluzimele lokugcina amandla, inani lamadivayisi we-semiconductor yamandla cishe izikhathi ezingu-1.5 ze-photovoltaic. Njengamanje, isitoreji se-optical singabala ngaphezu kuka-60-70%, futhi uhlelo oluhlukile lokugcina amandla lubalelwa ku-30%.
Umfanekiso: Imojula ye-BYD IGBT
I-IGBT inezinhlobonhlobo zezendlalelo zohlelo lokusebenza, ezinenzuzo kakhulu kune-MOSFET ku-inverter yokugcina amandla. Kumaphrojekthi angempela, i-IGBT kancane kancane ithathe indawo ye-MOSFET njengethuluzi eliyinhloko lama-photovoltaic inverters kanye nokukhiqizwa kwamandla omoya. Ukuthuthukiswa okusheshayo kwemboni entsha yokuphehla amandla kuzoba umfutho omusha wemboni ye-IGBT.
I-IGBT iyisisetshenziswa esiwumgogodla sokuguqula amandla kanye nokudlulisa
I-IGBT ingaqondwa ngokugcwele njenge-transistor elawula i-electronic two -way (multi-directional) egeleza nokulawula ama-valve.
I-IGBT iyinhlanganisela ye-full -control voltage -driven power semiconductor device eyakhiwa i-BJT bipolar triode kanye ne-insulating grid field effect tube. Izinzuzo zezici ezimbili zokwehla kwengcindezi.
Umfanekiso: Umdwebo wesakhiwo semojuli ye-IGBT
Umsebenzi wokushintsha we-IGBT uwukwakha isiteshi ngokwengeza i-positive voltage yesango ukuze unikeze isisekelo samanje ku-PNP transistor ukushayela i-IGBT. Ngokuphambene, engeza i-voltage yomnyango ophambene ukuze ukhiphe isiteshi, ugeleze ku-reverse base current, futhi uvale i-IGBT. Indlela yokushayela ye-IGBT ngokuyisisekelo iyafana naleyo ye-MOSFET. Idinga kuphela ukulawula isigxobo sokufaka i-N one-channel MOSFET, ngakho-ke inezici eziphezulu zokufakwayo kokufakwayo.
I-IGBT iyithuluzi eliwumongo lokuguqulwa kwamandla kanye nokudluliselwa. Ngokuvamile kwaziwa ngokuthi “i-CPU” yezinto zikagesi zikagesi. Njengemboni kazwelonke yamasu asafufusa, isetshenziswe kabanzi kumishini emisha yamandla nakweminye imikhakha.
I-IGBT inezinzuzo eziningi ezihlanganisa i-impedance ephezulu yokufaka, amandla okulawula aphansi, isifunda sokushayela esilula, isivinini sokushintsha ngokushesha, isimo samanje esikhulu, ingcindezi encishisiwe yokuphambukisa, nokulahlekelwa okuncane. Ngakho-ke, inezinzuzo eziphelele endaweni yemakethe yamanje.
Ngakho-ke, i-IGBT isiphenduke imakethe ye-semiconductor yamandla yamanje. Isetshenziswa kabanzi ezindaweni eziningi ezifana nokukhiqiza amandla amasha, izimoto zikagesi kanye nezinqwaba zokushaja, imikhumbi efakwe ugesi, ukuhanjiswa kwe-DC, ukugcinwa kwamandla, ukulawulwa kukagesi wezimboni nokonga amandla.
Umfanekiso:I-InfineonI-IGBT module
Ukuhlukaniswa kwe-IGBT
Ngokwesakhiwo somkhiqizo ohlukile, i-IGBT inezinhlobo ezintathu: ipayipi elilodwa, imojula ye-IGBT kanye ne-smart power module IPM.
(Izinqwaba zokushaja) nezinye izinkambu (ikakhulukazi imikhiqizo enjalo ethengiswayo emakethe yamanje). Imojula yamandla ehlakaniphile i-IPM isetshenziswa kakhulu emkhakheni wemishini yasendlini emhlophe njengama-air conditioner kanye nemishini yokuwasha yokuguqula imvamisa.
Ngokuya nge-voltage yesimo sohlelo lokusebenza, i-IGBT inezinhlobo ezifana ne-ultra -low voltage, low voltage, medium voltage kanye ne-high voltage.
Phakathi kwazo, i-IGBT esetshenziswa izimoto zamandla amasha, izilawuli zezimboni, kanye nemishini yasendlini ikakhulukazi inamandla kagesi aphakathi nendawo, kanti ezokuthutha ngojantshi, ukukhiqizwa kwamandla amasha namagridi ahlakaniphile anezidingo zamandla kagesi aphezulu, ikakhulukazi asebenzisa i-high -voltage IGBT.
I-IGBT ibonakala kakhulu ngendlela yamamojula. Idatha ye-IHS ibonisa ukuthi ingxenye yamamojula neshubhu eyodwa ingu-3: 1. Imojula ingumkhiqizo we-semiconductor oyimodular owenziwe chip ye-IGBT ne-FWD (i-continuing diode chip) ngebhuloho lesifunda elenziwe ngokwezifiso, futhi ngokusebenzisa amafreyimu epulasitiki, ama-substrates nama-substrates. , njll.

Izinkampani zaseShayina zikhula ngokushesha, futhi okwamanje zincike ekuthengeni kwamanye amazwe
Ngo-2022, imboni yezwe lami ye-IGBT ibe nomphumela oyizigidi ezingama-41, nesidingo esibalelwa ezigidini eziyi-156, kanye nezinga lokuzanelisa elingu-26.3%. Njengamanje, imakethe yasekhaya ye-IGBT igcwele kakhulu abakhiqizi baphesheya kwezilwandle abanjengo-Yingfei Ling, Mitsubishi Motor, kanye ne-Fuji Electric, ingxenye yabo ephakeme kakhulu i-Yingfei Ling, engu-15.9%.
Imakethe yemojula ye-IGBT i-CR3 ifinyelele ku-56.91%, kanti isamba sesabelo sabakhiqizi basekhaya i-Star Director kanye nenkathi ye-CRRC engu-5.01% sasingu-5.01%. Isabelo semakethe sabakhiqizi abathathu abaphezulu bedivayisi yokuhlukanisa i-IGBT yomhlaba wonke sifinyelele ku-53.24%.
