He aha te mea te MISFET?

tonu Huānga turanga o ngā pūrere Semiconductor ki te tupu. Ia tenenga hou i roto i te parae, i roto i te meka, te whakaaro o te huri pūnaha hiko katoa. Te huri kaha hoahoa ara iahiko i roto i te hoahoa whakaaro hou kitea ki runga ki a ratou. Mai te tenenga o te transistor tuatahi (1948 g) i haere te wa roa. I whakaaro te reira i te hanganga "PnP" me "npn", transistors pourua. Nāwai puta mis transistor mahi rite ki te parau tumu o huringa i roto i te kawenga hiko o te apa mata Semiconductor i raro i te mana o te mara hiko. No reira te ingoa tetahi mo tenei huānga - he mara.

TIR whakarāpopototanga iho (whakarewa-insulator-Semiconductor) faaite i te hanganga ā-o tenei taputapu. Na pono, te marumaru e taratahi reira i te pūtake me te awakeri ki te kahupapa kore-conductive. Modern transistor mis kua he roa te kuwaha o 0.6 microns. Na roto i te reira anake e taea tika he mara hiko - e pānga ki te āhua hiko o te Semiconductor.

Kia titiro a ki te pehea te transistor mara-pānga, ka kitea i roto i te mea ko te rerekētanga matua i pourua "teina." A, no te te kaha e tika ana i tona kuwaha reira ko te mara hiko. Pānga ki te ātete o te huinga huinga pūtake-awakeri. Tenei te tahi mau maitai o te whakamahi i tenei pūrere.

• I roto i te whakawhitinga resistance ara awakeri-puna tuwhera āhua he iti rawa, a kua kua pai whakamahia Mis transistor hei kī hiko. Hei tauira, kia whakahaere i te reira tīwerawera whakahaere, bypassing te kawenga ranei ki te whai wāhi i roto i te iahiko arorau.
• Hoki o mōhio me te parenga ia tāuru tiketike o te pūrere. Ko te tino hāngai ana tēnei kōwhiringa ka mahi i roto i iahiko iti-ngaohiko.
• Low kaha awakeri-pūtake whakawhitinga taea Mis transistor i roto i ngā pūrere tiketike-auau. I raro i kore distortion puta i roto i tohu tuku.
• Whanaketanga o ngā hangarau hou i roto i te hanga o ngā huānga arahina ki te hanga o te IGBT-transistors, e te whakakotahi nga mau huru pai o te parae, me ngā pūtau pourua. Kei te whānui kōwae Power i runga i a ratou whakamahia i roto i tīmata maeneene me pūtahuri auau.

I roto i te hoahoa me te mahi o enei āhuatanga me tangohia ki pūkete e he tino tairongo ki overvoltage i te ara iahiko, me te transistors Mis hiko pateko. E ko, e taea te pakaru te pūrere ki te pa ki a koutou te terminals mana. A, no te tāuta te tango i te whakamahi uhupoho motuhake ranei.

Tuhinga mo te whakamahi o tenei pūrere ko te tino pai. Nā ki ona āhuatanga ahurei, Kei te whānui whakamahia te reira i roto i ngā taputapu hiko. tohutohu auaha i roto i te hikohiko hou ko te whakamahi o te kaha IGBT-kōwae mō te mahi i roto i ngā ara iahiko, tae atu, me te arataki.

Kei te pai ake tonu te hangarau o ratou production. Kei te whakawhanakehia te reira mo te roa tauine (whakaiti) kuwaha. Tenei ka whakapai ake i te tawhā mahi kua pai o te pūrere.
