I kēia manawa, aia nō ka ʻoihana semiconductor i ka pōʻai iho,ka ʻoihana chipke alo nei i ke koʻikoʻi o nā mea kūʻai aku e ʻoki ana i nā kauoha a hāʻule nā kumukūʻai huahana, akā aia ʻo IGBT i nā noi nui ʻelua o nā kaʻa uila a me ka noi photovoltaic solar, ka huhū huhū o nā waiwai, ka hemahema o ka nui, ʻaʻole wale ke kumukūʻai i piʻi i ka lani, ʻaʻole ʻo ka ʻoihana "pehea ke kiʻekiʻe o ke kumukūʻai o ka pilikia, akā ʻaʻole hiki ke kūʻai" e wehewehe i ke kūlana hemahema.
ʻO IGBT wale nō ka māhele o nā ʻāpana semiconductor i hiki ke hoʻonui i kāna kumukūʻai a ma mua o ke koi ʻana i ke ala āpau, ʻoi loa ma muli o ka palena palena o nā huahana i kēia manawa, akā ʻo ka hana pupule o nā mea kanu lā, he nui ko lākou inverters. koi no nā IGBT, i hui pū ʻia me ke koi kiʻekiʻe o nā IGBT i nā kaʻa uila, ua hopu pinepine nā mea hana kaʻa nui iā lākou.
Ua hōʻike ʻia ʻo IGBT kahi mea hoʻololi mana, me ka inoa o ka "power electronics CPU", he mea mana semiconductor i hoʻoiho ʻia i ka voltage i haku ʻia me BJT (bipolar junction transistor) a me MOSFET (gold oxygen half field effect transistor), me nā mea maikaʻi. o ke kiʻekiʻe hoʻokomo impedance, kiʻekiʻe kū i ka uila a me ka haʻahaʻa ma ka moku'āina hāʻule uila.
Me ka piʻi ʻana o nā kaʻa ikehu hou, ua piʻi nui ka noi no ka volta kiʻekiʻe, a ua lilo nā IGBT i mea nui o ka hoʻomohala ʻoihana.ʻO ka nui o nā IGBT i hoʻohana ʻia i loko o kahi kaʻa uila he kiʻekiʻe e like me nā haneli, ʻo ia ʻehiku a ʻumi paha ka nui o nā kaʻa wahie kahiko.I loko o nā noi ʻoihana, aia nā kaʻa AC servo, nā mea hoʻohuli, ka makani a me ka mana o ka lā a me nā noi mana ʻōmaʻomaʻo ʻē aʻe, a ma ka ʻāpana uila kiʻekiʻe, aia nā ala kaʻa kiʻekiʻe a me nā kaʻa kaʻa a me nā noi mana.
No ka noi oNā IGBTma ke kula la, aia ma ka inverter.Ma ke ʻano he mana hoʻololi mana, hiki i ka mea hoʻohuli ke hoʻololi i ka mana i mālama ʻia i loko o ka panel solar i ka uila i loaʻa maʻamau, me ka ʻole o ka inverter, ʻaʻole hiki ke hana ka mana a loaʻa kahi kūlana pivotal i ke kūkulu ʻana i nā mea kanu lā.
Ua hōʻike ka ʻoihana lā me ka piʻi ʻana o ka hoʻomohala ʻana o ka mana o ka mana, ʻo ka module mana kiʻekiʻe ke ʻano o ka mākeke nui, a hiki ke hoʻomaikaʻi maikaʻi i ka hoʻihoʻi ʻana mai o ka hoʻopukapuka ʻana o nā mea kanu mana, no laila nui nā mea hoʻohuli lā e lawe mai i ka IGBT ma ke ʻano he ʻāpana mana, ua hoʻomaka pū ka makemake e ulu.
E kamaʻilio e pili ana i ka pōkole o IGBT?Ua ʻōlelo pololei ʻo Moody's Chairman Ye Zhengxian, ʻaʻole he mea hou ka piʻi ʻana o ke kumukūʻai, ʻaʻole ka pilikia o nā kumukūʻai kiʻekiʻe, akā ʻaʻole hiki ke kūʻai, ua hoʻoholo ka haʻawina e hoʻomau ka nalu o ka hemahema no kekahi manawa.
Eia kekahi, e like me ke kaulahao hoʻolako, ua hoʻonui ʻo Hanlei i ke kumu kūʻai o ka laina hana IGBT ma kahi o 10% ma mua o kēia makahiki, a i ka wā i hoʻoponopono ʻia ai ka makana wafer foundry, ua hoʻonui ʻo Hanlei i ke kumukūʻai kūʻē i ke ʻano, e hōʻike ana i nā kūlana mākeke wela. .
Wahi a ka "2023 Q1 Chip Market Report" i hoʻokuʻu ʻia e Future Electronics ma Pepeluali 17, 2023, ka IGBT Q1 o ST (STMicroelectronics), Microsemi, Infineon, IXYS a meFairchild(Fairchild Semiconductor), nā hōʻailona nui ʻelima, e like me ka manawa o ka hoʻopuka ʻana o 2022 Q4, me ka paʻa o ka manawa hāʻawi i 54 mau pule ma ka lōʻihi loa.
Ma kahi kikoʻī, i ka hapaha mua o 2023, ʻo ka manawa alakaʻi IGBT o ST he 47-52 mau pule, ʻo ka manawa alakaʻi IGBT o Microsemi he 42-52 mau pule, ʻo ka manawa alakaʻi IGBT o IXYS he 50-54 mau pule, ʻo ka manawa alakaʻi IGBT o Infineon he 39-50 mau pule, a ʻO ka manawa alakaʻi IGBT o Fairchild he 39-52 mau pule.Eia naʻe, paʻa nā ʻano hoʻouna a me nā kumukūʻai o kēia mau hōʻailona nui 5, me ka ʻole o ka piʻi ʻana.
ʻO ka nānā ʻana o ka ʻoihana, ʻelua kumu nui no ka hapa nui o nā IGBT, ʻo ka mea mua, ʻo ka nui o kēia manawa o nā inverters solar e hoʻohana ana i nā IGBT ua piʻi nui.ʻO ka lua, ʻo ka ʻoihana semiconductor i kēia manawa i ka manawa hoʻoponopono, ʻaʻole wale ka palena o ka hiki, akā ua lawe ʻia ka nui o ka mana e nā hale hana kaʻa uila, ka hopena o ka hapa nui o nā IGBT ma lalo o ka hopena crowding out.
