He ngōhiko Semiconductor. pūtake o te hikohiko

Ki te momo katoa o te turanga huānga hou o te hikohiko kore me wareware e te hāngai ai ki runga ki nga mea tino māmā, tetahi o i te mea he ngōhiko Semiconductor.

Me kï reira tonu e i mawhiti tuatahi ko reira he huānga ohie. I roto i te meka, tona whakamahi taea ki te whakaoti i te momo o ngā mahi i roto i te mara o te hikohiko me te engineering hiko. e kore he uaua rawa te hangarau o te hanga o taua whakaaro.

Kei te ngōhiko o e rua rerekē i roto i te momo kawe o ngā rauemi i huaina rohe n-kawe ia me te p-kawe. Ki te whakaaro tatou te parau tumu o te mahi o te ngōhiko Semiconductor, ki te hiahia haere ki taua mea rite PN komititanga, irahiko tukunga, tūringiringi, te tahi atu pānga tinana rite. Na reira, ka mahue i te kōrero o enei pātai mo tetahi atu take, te whakamahi i te whakarite. Whakatauritea te ngōhiko Semiconductor pea he piha. Nā ki tona hanganga, arā, o rua rerekē kawe ia momo rauemi i roto i te pūrere taua i reira he kawe ia unilateral, e te tikanga e te nāianei hiko e taea i roto i te reira i rere noa i roto i te kotahi aronga. Ko te taua tupu, no te whakamahi i te piha - rangi te wai ranei e taea te haere anake i roto i te kotahi aronga. Tauira - pahikara kāmera: ki te hau rere, a hoki - e kore.

e mea he pānga tino māmā - kawe ia kotahi-ara, engari homai he rota o ngā whai wāhitanga ki te whakamahi i te reira i roto i te whakamahi i ngā. I roto i ngā, mahi he ngōhiko Semiconductor AC ki DC faafariuraa. He he he piha katoa o ngā hua i huaina te p rectifier.

mahi ratou rite noa te piha. A, no te hāngai te wehenga tawhiti o te ngaohiko tono ki te hua ki te hiahiatia, arā, ka tono te ngaohiko tāpiri e ki te tāpiri pūrere me tango ki te haunga te, na roto i te nāianei hiko, ki te kahore, kahore tupu.

Ko reira e tika ana ki te pānga e tahuri whakaahuatia ngaohiko AC ki te tetahi tūturu. tukua te ara iahiko tāuru te ki te ngaohiko tauutuutu, ko te ngaohiko puta noa i te Semiconductor haere anake te wehenga tawhiti tika. Ka rite ki te hua, te tiki matou te ngaohiko whakaputa o tetahi anake wehenga tawhiti, i te panapana, arā rerekē i roto i te kaha tīwera.

e kore ko te anake kotahi tono o tenei pūrere Semiconductor. I te huinga PN, e ko te pūtake o te ngōhiko, i reira e te tahi atu āhuatanga, he tokomaha o nei e tautuhi āta i roto i tona ahumahi. Enei āhuatanga Ko te pūtake mo te tahi atu, ngaahi kalasi pūrere rawa rerekē. Tenei te p zener, tiketike-auau, me te p pākau i, varicap, photodiodes, LED, me ētahi atu Ko e hāngai ana katoa o ratou i runga i nga āhuatanga o te huinga PN.

Heoi, i reira e he piha o ngā pūrere, i huaina "Semiconductor Gunn ngōhiko", e kore e pā ana ki te hanganga o te whakawhitinga taua. hāngai ana ratou mahi i runga i te pānga Gunn pera-ka karanga. Kei te meinga te reira e te huinga matatini o ari puta i roto i te maramara Semiconductor i raro i etahi pānga waho. Ka rite ki te hua o enei tukanga te nāianei e rere i roto i te karaihe taui ona oscillations puta. Ko mo ratou whakatupuranga, me te whakamahi i ngā pūrere taua. Kei te nuinga whakamahia ratou i roto i te hangarau ngaruiti rite te puna o wiri.

Te p ko te wāhi o tetahi pūrere hiko. E whakamahia ratou mo wehe me te faafariuraa ngaohiko, stabilization, tātari haruru; māmā ki te whakarārangi i te take te wahi e kore e ratou whakamahia. Hoki ratou, i reira he momo rerekē o te whare, hangaia hoki he momo o ngā me ngaohiko me tāuta e rua i roto i te wāhi me te putanga iahiko i roto i ngā pūrere hiko. Ngōhiko - te reira pea tetahi o nga whakaaro Semiconductor tino noa.

Na e matau ana koutou ki ta te ngōhiko Semiconductor, me aha he nga kōwhiringa mo tona whakamahi.
