Waqtigan xaadirka ah, warshadaha semiconductor-ka ayaa wali ku jira wareegga hoose,warshadaha chipayaa guud ahaan la kulma cadaadiska macaamiisha goynta amarada iyo hoos u dhaca qiimaha alaabta, laakiin IGBT waxay ku jirtaa labada codsi ee caadiga ah ee baabuurta korantada iyo baahida sawir-qaadista qoraxda, degdega waalan ee alaabta, yaraanta dhow ee weyn, ma aha oo kaliya qiimaha ayaa kor u kacay cirka, warshaduhu maaha "inta qiimaha dhibaatada, laakiin si fudud ma iibsan karaan" si loo qeexo xaaladda yaraanta.
IGBT waa qaybta kaliya ee qaybaha semiconductor kuwaas oo awooday inay kordhiyaan qiimahooda oo ay ka baxaan baahida oo dhan, inta badan sababtoo ah sahayda xaddidan ee alaabta marxaladdan, laakiin dhismaha waalan ee dhirta tamarta qoraxda, rogoyaashooda ayaa leh mid aad u weyn. Baahida IGBT-yada, oo ay weheliso baahida sare ee IGBT-yada ee baabuurta korantada, soosaarayaasha baabuurta ayaa si joogto ah u qabsaday.
Waxaa lagu soo waramayaa in IGBT ay tahay qayb koronto beddeleysa, oo leh sumcadda "awoodda elektiroonigga ah ee CPU", waa korantada korantada korantada korantada korantada ka kooban BJT ( transistor-ka laba-cirifoodka) iyo MOSFET ( transistor-ka qayb ka mid ah oxygen-ka dahabka ah), oo leh faa'iidooyinka ee impedance sare, danab adkeysi sare iyo hoos-u-state danab.
Kor u kaca baabuurta tamarta cusub, baahida loo qabo koronta sare ayaa si aad ah u kordhay, iyo IGBTs waxay noqdeen diiradda horumarinta warshadaha.Tirada IGBT-yada loo isticmaalo gaadhi koronto ah ayaa gaadhaysa boqollaal, taas oo todoba ilaa toban jeer ka badan baabuurta shiidaalka ee caadiga ah.Codsiyada warshadaha, waxaa jira matoorrada AC servo, rogayaasha, dabaysha iyo tamarta tamarta qoraxda iyo codsiyada kale ee tamarta cagaaran, iyo qaybta korantada sare, waxaa jira waddooyin tareen xawaare sare leh iyo gaadiid kale oo tareen iyo codsiyo koronto ah.
Sida codsiga eeIGBTsbeerta qoraxda, waa inverter-ka.Qalab beddelka korontadu ahaan, roog-gudbigu waxa uu u beddeli karaa tamarta ku kaydsan leydhka cadceedda oo uu u beddelo koronta guud ee la heli karo, iyada oo aan la beddelan, warshadda korontadu ma shaqayn karto oo waxa ay leedahay boos udub-dhexaad u ah dhismaha xarumaha tamarta qoraxda.
Warshadaha qoraxda ayaa tilmaamay in kororka korantada ee moduleka qoraxda ee hufnaanta, moduleka awoodda sare uu ahaa isbeddelka suuqa caadiga ah, oo si wax ku ool ah u wanaajin karo soo celinta maalgashiga hawlwadeennada warshadda korontada, sidaas awgeed qaar badan oo ka mid ah beddelayaasha qoraxda ayaa hadda soo dhoofin doona IGBT sida qayb ka mid ah tamarta, baahida ayaa sidoo kale bilaabay in ay koraan.
Ka hadlida sida gaaban ee IGBT?Guddoomiyaha Moody's Ye Zhengxian ayaa si bareer ah u sheegay in kororka qiimaha uusan ahayn wax cusub, maaha dhibaatada sicirka sare, laakiin si fudud ma iibsan karo, daraasaddu waxay soo gabagabeysay in mowjadda yaraanta ay sii socon doonto muddo.
Intaa waxaa dheer, marka loo eego silsiladda sahayda, Hanlei waxay kordhisay qiimaha aasaaska ee khadka wax soo saarka ee IGBT illaa 10% horaantii sanadkan, iyo markii dalabka fayraska wafer guud ahaan dib loo hagaajiyay, Hanlei wuxuu kordhay qiimaha ka dhanka ah isbeddelka, isagoo muujinaya xaaladaha suuqa kulul. .
Marka loo eego xogta "2023 Q1 Chip Market Report" ee ay soo saartay Electronics Future Febraayo 17, 2023, IGBT Q1 ee ST (STMicroelectronics), Microsemi, Infineon, IXYS iyoFairchild(Fairchild Semiconductor), shanta nooc ee waaweyn, ayaa asal ahaan la mid ah xilliga dhalmada ee 2022 Q4, iyada oo xilliga dhalmada ay weli adag tahay 54 toddobaad ugu dheer.
Gaar ahaan, rubuci hore ee 2023, wakhtiga hogaanka ST ee IGBT waa 47-52 todobaad, Microsemi's IGBT wakhtiga hogaanka waa 42-52 todobaad, IXYS's IGBT wakhtiga hogaanka waa 50-54 todobaad, Infineon's IGBT wakhtiga hogaanka waa 39-50 todobaad, iyo Waqtiga hogaanka Fairchild's IGBT waa 39-52 toddobaad.Si kastaba ha ahaatee, isbeddellada shixnadaha iyo isbeddellada qiimaha ee 5-tan nooc ee waaweyn waa kuwo deggan, oo aan lahayn isbeddel sare.
Falanqaynta warshadaha, waxaa jira laba sababood oo waaweyn oo ah yaraanta weyn ee IGBTs, marka hore waa saamiga hadda jira ee rogayaasha qoraxda ee isticmaalaya IGBTs ayaa si aad ah u kordhay.Midda labaad ayaa ah in warshadaha semiconductor-ku ay hadda ku jiraan muddada hagaajinta, kaliya ma aha awoodda xaddidan, laakiin sidoo kale in badan oo ka mid ah awoodda ayaa laga qaaday warshadaha baabuurta korontada, taasoo keentay yaraanta IGBT-yada weyn ee hoos yimaada saameynta ciriiriga ah.
