Okwangoku, ishishini le-semiconductor lisekho kumjikelo osezantsi,ishishini letshiphungokuqhelekileyo ijongene noxinzelelo lwabathengi bokusika ii-odolo kunye namaxabiso emveliso ehlayo, kodwa i-IGBT ikwizicelo ezibini eziphambili zezithuthi zombane kunye nemfuno ye-photovoltaic yelanga, ukungxama kwempahla, ukunqongophala kwamva nje kokukhulu, kungekhona nje ixabiso eliye laphakama. sky, ishishini alikho "ixabiso eliphezulu lengxaki, kodwa alikwazi ukuthenga" ukuchaza imeko yokunqongophala.
I-IGBT lolona didi lodwa lwamacandelo e-semiconductor oluye lwakwazi ukunyusa ixabiso lalo kwaye lugqithise imfuno yonke indlela, ikakhulu ngenxa yokubonelelwa okulinganiselweyo kweemveliso kweli nqanaba, kodwa ukwakhiwa okuphambeneyo kwezityalo zamandla elanga, ii-inverters zazo zinamandla amakhulu. Imfuno yee-IGBTs, idityaniswa nemfuno ephezulu yee-IGBT kwizithuthi zombane, abenzi beemoto abakhulu bahlala bezihlutha.
Kuxelwa ukuba i-IGBT yinto yokutshintsha amandla, enegama elithi "power electronics CPU", yinto yamandla eqhutywa nge-voltage semiconductor eyenziwe yi-BJT (bipolar junction transistor) kunye ne-MOSFET (igolide ye-oxygen half field effect transistor), kunye nezibonelelo. I-impedance ephezulu, ukumelana nombane ophezulu kunye nokuhla kwamandla ombane aphantsi.
Ngokunyuka kwezithuthi zamandla amatsha, imfuno yombane ophezulu inyuke kakhulu, kwaye ii-IGBT ziye zaba yinto ekugxilwe kuyo kuphuhliso lwemizi-mveliso.Inani lee-IGBT ezisetyenziswa kwisithuthi sombane liphezulu ukuya kumakhulu, eliphindwe kasixhenxe ukuya kwishumi leemoto zamafutha eziqhelekileyo.Kwizicelo zamashishini, kukho ii-AC servo motors, ii-inverters, ukuveliswa kwamandla omoya kunye nelanga kunye nezinye izicelo zamandla aluhlaza, kwaye kwicandelo lamandla ombane aphezulu, kukho iindlela zikaloliwe ezihamba ngesantya esiphezulu kunye nolunye uthutho lukaloliwe kunye nokusetyenziswa kwegridi yamandla.
Ngokuphathelele ukusetyenziswa kweIi-IGBTskwintsimi yelanga, ikwi-inverter.Njengesixhobo sokuguqula amandla, i-inverter inokuguqula amandla agcinwe kwipaneli yelanga kumbane okhoyo ngokubanzi, ngaphandle kwe-inverter, isityalo samandla asikwazi ukusebenza kwaye sinendawo ebalulekileyo ekwakhiweni kwezityalo zamandla elanga.
Ishishini lelanga libonise ukuba ngokunyuka kokukhula kwemodyuli yokuvelisa amandla elanga, imodyuli ephezulu yamandla ibe yeyona nto iphambili kwimarike, kwaye inokuphucula ngokufanelekileyo imbuyekezo kutyalo-mali lwabaqhubi beplanti yamandla, uninzi lwabaguquli belanga ngoku baya kungenisa i-IGBT njenge icandelo lamandla, imfuno nayo iqalile ukukhula.
Ukuthetha malunga nokuba mfutshane kangakanani kwi-IGBT?USihlalo kaMoody uYe Zhengxian ngeliphandle wathi ukunyuka kwamaxabiso ayisiyonto intsha, ayisiyongxaki yamaxabiso aphezulu, kodwa ayinakuthenga, uphononongo lugqibe kwelokuba ukunqongophala kuya kuqhubeka okwethutyana.
Ukongeza, ngokutsho kwekhonkco lokubonelela, uHanlei wonyuse ixabiso lesiseko somgca wemveliso we-IGBT malunga ne-10% ekuqaleni kwalo nyaka, kwaye xa isibonelelo se-wafer foundry sahlengahlengiswa ngokubanzi, uHanlei wonyusa ixabiso ngokuchasene nomkhwa, eqaqambisa iimeko zentengiso ezishushu. .
Ngokutsho kwe "2023 Q1 Chip Market Report" idatha ekhutshwe yiFuture Electronics ngoFebruwari 17, 2023, IGBT Q1 ye-ST (STMicroelectronics), iMicrosemi, Infineon, IXYS kunyeFairchild(I-Fairchild Semiconductor), ii-brand ezinkulu ezintlanu, zihlala zifana nexesha lokuhanjiswa kwe-2022 Q4, kunye nexesha lokuhambisa lihlala liqinile kwiiveki ezingama-54 kwezona zininzi.
Ngokukodwa, kwikota yokuqala ye-2023, i-ST's IGBT ixesha elihamba phambili li-47-52 iiveki, ixesha lokuhamba le-Microsemi's IGBT iiveki ze-42-52, ixesha lokuhamba kwe-IXYS IGBT yiiveki ze-50-54, ixesha lokuhamba kwe-IGBT ye-Infineon iiveki ze-39-50, kwaye Ixesha lokukhokela le-IGBT likaFairchild ziiveki ezingama-39-52.Nangona kunjalo, iindlela zokuthumela kunye neentsingiselo zamaxabiso ezi mpawu zinkulu ze-5 zizinzile, azikho ukunyuka.
Uhlalutyo lweshishini, kukho izizathu ezibini eziphambili zokunqongophala okukhulu kwe-IGBTs, eyokuqala inxalenye yangoku ye-solar inverters usebenzisa i-IGBT inyuke kakhulu.Okwesibini kukuba imboni ye-semiconductor okwangoku ikwixesha lohlengahlengiso, kungekhona nje amandla alinganiselweyo, kodwa kunye nobuninzi bomthamo buthatyathwe ziifektri zezithuthi zombane, okubangele ukunqongophala okukhulu kwe-IGBT phantsi kwempembelelo yokuxinana.
