Kugeza ubu, inganda za semiconductor ziracyari mu ntera yo hasi,ingandamuri rusange ihura nigitutu cyabakiriya bagabanya ibicuruzwa no kugabanuka kwibiciro byibicuruzwa, ariko IGBT iri muburyo bubiri bukoreshwa bwimodoka zikoresha amashanyarazi hamwe nizuba ryifoto yizuba, kwihuta kwibicuruzwa, ibura rya vuba ryibinini, ntabwo igiciro cyazamutse kugera kuri ikirere, inganda ntabwo "burya igiciro cyikibazo kiri hejuru, ariko ntishobora kugura" kugirango dusobanure ikibazo cyibura.
IGBT nicyiciro cyonyine cyibice bya semiconductor byashoboye kongera igiciro cyacyo no kurenza icyifuzo cyose, cyane cyane kubera ibicuruzwa bike muri iki cyiciro, ariko kubaka ibisazi by’amashanyarazi akomoka ku mirasire y'izuba, inverter zabo zifite nini cyane icyifuzo cya IGBTs, hamwe no gukenera cyane IGBT mu binyabiziga byamashanyarazi, abakora imodoka nini bagiye babifata.
Biravugwa ko IGBT ari ikintu cyo guhindura amashanyarazi, kizwi cyane kuri "power electronics CPU", ni voltage ikoreshwa na semiconductor power element igizwe na BJT (bipolar junction transistor) na MOSFET (zahabu ya ogisijeni igice cya kabiri cya transistor), hamwe nibyiza yo kwinjiza cyane impedance, ihangane cyane na voltage hamwe na leta ya voltage igabanuka.
Hamwe n’izamuka ry’ibinyabiziga bishya by’ingufu, icyifuzo cya voltage nyinshi cyiyongereye cyane, kandi IGBTs yibanze ku iterambere ry’inganda.Umubare wa IGBTs ukoreshwa mu modoka y’amashanyarazi ugera ku magana, ibyo bikubye inshuro zirindwi kugeza ku icumi z’imodoka gakondo.Mu nganda zikoreshwa mu nganda, hari moteri ya AC servo, inverters, ingufu z'umuyaga nizuba hamwe nizindi mbaraga zikoresha amashanyarazi, kandi mugice cya voltage ndende, hariho gari ya moshi yihuta nibindi bitwara gari ya moshi hamwe nogukoresha amashanyarazi.
Kubijyanye no gusabaIGBTsmumirasire y'izuba, iri muri inverter.Nkigikoresho cyo guhindura amashanyarazi, inverter irashobora guhindura ingufu zibitswe mumirasire yizuba kumashanyarazi asanzwe aboneka, hatabayeho inverter, urugomero rwamashanyarazi ntirushobora gukora kandi rufite umwanya wingenzi mukubaka amashanyarazi akomoka kumirasire y'izuba.
Inganda zikomoka ku mirasire y'izuba zagaragaje ko hamwe n’ihindagurika ry’imihindagurikire y’amashanyarazi akomoka ku mirasire y'izuba, module y’amashanyarazi nini niyo yabaye isoko nyamukuru ku isoko, kandi irashobora guteza imbere neza inyungu ku ishoramari ry’abakora amashanyarazi, ku buryo inverter nyinshi zituruka ku zuba zizatumiza IGBT nka a ibice by'imbaraga, ibyifuzo nabyo byatangiye gutera imbere.
Muganira kubyerekeranye na IGBT?Umuyobozi wa Moody, Ye Zhengxian, yavuze yeruye ko izamuka ry’ibiciro atari ikintu gishya, ko atari ikibazo cy’ibiciro biri hejuru, ariko ko ridashobora kugura gusa, ubushakashatsi bwanzuye ko ikibazo cy’ibura kizakomeza igihe gito.
Byongeye kandi, ukurikije urwego rutanga amasoko, Hanlei yazamuye igiciro cy’ibanze cy’umurongo w’umusaruro wa IGBT ku kigero cya 10% mu ntangiriro zuyu mwaka, kandi igihe itangwa ry’uruganda rwa wafer ryahinduwe muri rusange, Hanlei yongereye igiciro ku cyerekezo, agaragaza uko isoko rishyushye .
Dukurikije amakuru ya “2023 Q1 Chip Market Report” yashyizwe ahagaragara na Future Electronics ku ya 17 Gashyantare 2023, IGBT Q1 ya ST (STMicroelectronics), Microsemi, Infineon, IXYS naFairchild.
By'umwihariko, mu gihembwe cya mbere cya 2023, igihe cyo kuyobora IGBT cya ST ni ibyumweru 47-52, igihe cya IGBT cya Microsemi ni ibyumweru 42-52, IGBT yo kuyobora IGBT ni ibyumweru 50-54, IGBT ya Infineon ni ibyumweru 39-50, kandi IGBT ya Fairchild yo kuyobora ni ibyumweru 39-52.Nyamara, ibicuruzwa byoherejwe hamwe nibiciro byibi bicuruzwa 5 byingenzi birahagaze, nta kuzamuka kuzamuka.
Isesengura ry’inganda, hari impamvu ebyiri zingenzi zituma ibura ryinshi rya IGBTs, icya mbere nicyo kigereranyo cyubu cyoguhindura imirasire yizuba ukoresheje IGBTs cyiyongereye cyane.Iya kabiri ni uko inganda za semiconductor muri iki gihe ziri mu gihe cyo guhindura ibintu, ntabwo ubushobozi bugarukira gusa, ariko kandi n'ubushobozi bwinshi bwakuweho n’inganda z’imodoka zikoresha amashanyarazi, bikaviramo ikibazo kinini cya IGBTs kubera ingaruka z’abantu benshi.
