Nā ʻokoʻa ma waena o IGBT a me MOSFET

ʻO IGBT (Insulated Gate Bipolar Transistor) a me MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) ʻelua mau mea hana semiconductor mana maʻamau i hoʻohana nui ʻia i ka uila uila. ʻOiai he mau mea koʻikoʻi nā mea ʻelua i nā noi like ʻole, ʻokoʻa lākou i nā ʻano he nui. Aia ma lalo iho nā ʻokoʻa nui ma waena o IGBT a me MOSFET:

1. Kumu Hana

- IGBT: Hoʻohui ʻo IGBT i nā hiʻohiʻona o kahi BJT (Bipolar Junction Transistor) a me kahi MOSFET, e hoʻolilo iā ia i mea hana hybrid. Mālama ʻo ia i ke kumu o ka BJT ma o ka volta puka o kahi MOSFET, ʻo ia hoʻi ka mana o ka hoʻokele a me ka ʻoki ʻana o ka BJT. ʻOiai he paʻakikī ke kaʻina hana conduction a me ka ʻoki ʻana o kahi IGBT, e hōʻike ana i nā poho haʻahaʻa haʻahaʻa haʻahaʻa a me ka hoʻomanawanui kiʻekiʻe.

- MOSFET: MOSFET he transistor hopena e hoʻomalu i kēia manawa i loko o kahi semiconductor ma o ka volta puka. Ke ʻoi aku ka nui o ka volta o ka puka i ka volta kumu, puka mai kahi papa conductive, e hiki ai ke kahe i kēia manawa. ʻO ka mea ʻē aʻe, i ka wā ma lalo o ka paepae ka puka makani, nalowale ka papa conductive, a ʻaʻole hiki ke kahe ke au. He maʻalahi ka hana o kahi MOSFET, me ka wikiwiki o ka hoʻololi ʻana.

2. Na Wahi Noi

- IGBT: Ma muli o kona ʻae uila kiʻekiʻe, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, a me ka hoʻololi wikiwiki ʻana, kūpono loa ʻo IGBT no ka mana kiʻekiʻe, nā noi haʻahaʻa haʻahaʻa e like me nā inverters, nā mea hoʻokele kaʻa, nā mīkini welding, a me nā lako mana uninterruptible (UPS) . Ma kēia mau noi, hoʻokele maikaʻi ʻo IGBT i nā hana hoʻololi kiʻekiʻe a me nā hana hoʻololi kiʻekiʻe.

- MOSFET: MOSFET, me kāna pane wikiwiki, ke kūpaʻa hoʻokomo kiʻekiʻe, ka hana hoʻololi paʻa, a me ke kumu kūʻai haʻahaʻa, hoʻohana nui ʻia i nā noi haʻahaʻa haʻahaʻa, hoʻololi wikiwiki e like me nā lako mana hoʻololi, nā kukui, nā mea hoʻonui leo, a me nā kaapuni logic. . Hana maikaʻi loa ʻo MOSFET i nā noi haʻahaʻa haʻahaʻa a haʻahaʻa.
