Njengamanje, imboni ye-semiconductor isesesimweni esiphansi,imboni ye-chipngokuvamile ibhekene nengcindezi yamakhasimende okusika ama-oda kanye namanani entengo emikhiqizo ehlayo, kodwa i-IGBT isezinhlelweni ezimbili ezivamile zezimoto zikagesi kanye nesidingo se-solar photovoltaic, ukushesha kwezimpahla, ukushoda kwakamuva kwezimpahla ezinkulu, hhayi nje intengo ekhuphukele sky, imboni ayilona “intengo yenkinga iphezulu kangakanani, kodwa ayikwazi ukuthenga” ukuchaza isimo sokushoda.
I-IGBT iwukuphela kwesigaba sezingxenye ze-semiconductor esikwazile ukukhulisa intengo yayo futhi yadlula isidingo ngaso sonke isikhathi, ikakhulukazi ngenxa yokuhlinzekwa okulinganiselwe kwemikhiqizo kulesi sigaba, kodwa ukwakhiwa okuphambene kwezitshalo zamandla elanga, ama-inverters azo anesisindo esikhulu. isidingo sama-IGBT, kuhambisana nesidingo esikhulu sama-IGBT ezimotweni zikagesi, abakhiqizi bezimoto abakhulu bavame ukuwahlwitha.
Kubikwa ukuthi i-IGBT iyisici sokushintsha amandla, esinedumela elithi “power electronics CPU”, iyingxenye yamandla esemiconductor aqhutshwa yi-voltage eyakhiwa i-BJT (bipolar junction transistor) kanye ne-MOSFET (i-gold oxygen half field effect transistor), enezinzuzo. ye-impedance ephezulu yokufaka, i-voltage eqinile ephezulu kanye nokwehla kwe-voltage esezingeni eliphansi.
Ngokukhuphuka kwezimoto ezintsha zamandla, isidingo samandla kagesi aphezulu sikhule kakhulu, futhi ama-IGBT asephenduke ingqikithi yokuthuthukiswa kwezimboni.Inani lama-IGBT asetshenziswa ezimotweni ezisebenza ngogesi likhulu njengoba liphindwe kasikhombisa kuya kweyishumi kunezimoto ezisetshenziswa uphethiloli ezivamile.Ezimbonini zokusebenza, kukhona ama-AC servo motors, ama-inverter, amandla omoya kanye nelanga kanye nezinye izinhlelo zokusebenza zamandla aluhlaza, futhi engxenyeni yamandla kagesi aphezulu, kunojantshi wesitimela ohamba ngesivinini esikhulu nezinye izinto zokuhamba zikaloliwe kanye nezicelo zegridi yamandla.
Mayelana nokusetshenziswa kweI-IGBTsendaweni yelanga, iku-inverter.Njengedivayisi yokuguqula amandla, i-inverter ingaguqula amandla agcinwe kuphaneli yelanga kugesi otholakala ngokuvamile, ngaphandle kwe-inverter, isitshalo samandla asikwazi ukusebenza futhi sinesikhundla esibalulekile ekwakhiweni kwezitshalo zamandla elanga.
Imboni yelanga iveze ukuthi ngokukhula okwandayo kokusebenza kahle kokuphehla amandla kagesi wemojula yelanga, imojula yamandla aphezulu ibe umkhuba wemakethe ojwayelekile, futhi ingathuthukisa ngempumelelo ukubuyiselwa kokutshalwa kwezimali kwabaqhubi bezitshalo zamandla, ngakho-ke ama-solar inverters amaningi manje azongenisa i-IGBT njenge ingxenye yamandla, isidingo naso sesiqalile ukuchuma.
Ukhuluma ngokuthi imfushane kangakanani i-IGBT?USihlalo weMoody, uYe Zhengxian, uthe ukukhuphuka kwentengo akuyona into entsha, akuyona inkinga yamanani aphezulu, kodwa ayikwazi ukuthenga, ucwaningo luphethe ngokuthi igagasi lokushoda lisazoqhubeka isikhashana.
Ngaphezu kwalokho, ngokusho kochungechunge lokuhlinzeka, u-Hanlei unyuse intengo yokuqala yomugqa wokukhiqiza we-IGBT cishe ngo-10% ekuqaleni kwalo nyaka, kwathi lapho ukunikezwa kwe-wafer foundry ngokuvamile kushintshwa, u-Hanlei wenyusa intengo ngokumelene nomkhuba, egqamisa izimo zemakethe ezishisayo. .
Ngokusho kwedatha "ye-2023 Q1 Chip Market Report" ekhishwe yi-Future Electronics ngoFebhuwari 17, 2023, IGBT Q1 ye-ST (STMicroelectronics), Microsemi, Infineon, IXYS kanyeFairchild(I-Fairchild Semiconductor), izinhlobo ezinhlanu ezinkulu, zihlala zifana nesikhathi sokulethwa sango-2022 Q4, kanti isikhathi sokulethwa sihlala siqinile emavikini angama-54 isikhathi eside kakhulu.
Ngokuqondile, engxenyeni yokuqala ka-2023, isikhathi sokuhola se-ST's IGBT singamaviki angama-47-52, isikhathi sokuhola se-Microsemi's IGBT singamasonto angama-42-52, isikhathi sokuhola se-IXYS's IGBT singamaviki angama-50-54, isikhathi sokuhola se-Infineon's IGBT singamaviki angama-39-50, futhi Isikhathi sokuhola se-IGBT sika-Fairchild singamaviki angama-39-52.Kodwa-ke, izitayela zokuthunyelwa kanye nezintengo zalezi zinhlobo ezi-5 ezinkulu zizinzile, azinawo umkhuba okhuphukayo.
Ukuhlaziywa kwemboni, kunezizathu ezimbili eziyinhloko zokushoda okukhulu kwama-IGBT, eyokuqala ingxenye yamanje yama-solar inverters esebenzisa ama-IGBT inyuke kakhulu.Okwesibili ukuthi imboni ye-semiconductor okwamanje isesikhathini sokulungiswa, akukhona nje kuphela ukuthi umthamo ulinganiselwe, kodwa futhi amandla amaningi athathwe amafektri ezimoto zikagesi, okubangele ukushoda okukhulu kwama-IGBT ngaphansi komphumela wokuminyanisa.
