Rama rorohiko mana: ngōhiko me triode

Kia kōrero a pā ana ki te mapuni rorohiko whakahaeretia.

He aha te mea te rama rorohiko whakahaeretia?

rama rorohiko-te mana - he taputapu hiko ki te maha etahi o electrodes e ahunga he nāianei hiko anake i roto i te kotahi. Mai i te maha o electrodes tei runga i te ingoa o te rama: ngōhiko (e rua electrodes), he triode (e toru electrodes), pentode (e rima electrodes), me ētahi atu e whakamahia ratou i roto i te engineering hiko, hiko, te mana, me te tokomaha atu ahumahi ahu ki whakatika te nāianei hiko tauutuutu .. me te pā i te auau o nāianei, hei te pūoko ka whakawhiti i te porowhita mana. kahore koe e mohio he aha i reira he he ngōhiko me triode? Puta ki te whakatika i tēnei āputa.

ngōhiko

He ngōhiko Ko te rama rorohiko whakahaeretia i roto i nei i reira e rua electrodes. Te p me transistors o wae pūmārō rerekē ko te maha o electrodes, mahara tenei. I runga i te pūtake o te mau parau tumu i te pae tino, e tahuri iho te whakatinanatanga o to ratou taumahinga ki taua momo (aua, kua wehea ia momo ki te maha o iti-momo):

1. mārua Electric. Whakamahia mō te whakatikatika. A, no te tahu ki te pāmahana e hiahiatia ana o te pitoiho (ka reira te mea he paheke thermoelectric) te whangai ki te whanaunga pitoake ki te ngaohiko pitoiho he pai. Na he wahi o te irahiko tukua whakahaua ki te pitoake, me te nāianei ngōhiko i hanga te. Ki te kore e tenei tupu, ka te irahiko hoki ki te pitoiho.

2. Fakahoko. Whakamahia hoki amplifiers mana nui, me te stabilization o taumahatanga nui. Tohu i te pitoiho me te pitoake e whakanohoia i roto i te hau hau ranei ranunga e mangere i raro i te tetahi pēhanga.

3. Semiconductor. He tino kanorau tono pea. He whakaaro i roto i nei te whakawhiti hiko whakatikaina a reira e rua putanga waho. Ka rite ki whakatika i whakawhiti hiko ko te huinga PN, he whakapā Semiconductor-whakarewa giperperehoda ranei.

triode

ngōhiko Rerekē, triode, anake te pitoake me te pitoiho, a kua atu kawehiko mana, i huaina nei ko te mātiti. Kei waenganui i te pitoake me te pitoiho ki te whakahaere i te mātiti taea te irahiko rere rama na roto i te huri i te rahi me te wehenga tawhiti o te ngaohiko i waenganui i te mātiti me te pitoiho. Ko reira no te mea o tenei kaha kua huaina mana mātiti.

Net, i roto i te nuinga o te wā, ko te helix o waea angiangi i karapoti te pitoiho. Te whakaputa i te reira i te nika, molybdenum, ratou alloys, me tantalum, me Tungsten. Ko te raro te pūmanawa o te mātiti, kua ki te hanga i te irahiko haere ki te mara te atu mahi. I raro i etahi uara kino o te ngaohiko, e kore e kore irahiko e taea ki te aukati i te mara mātiti, me te nāianei pitoake o te transistor ka kia kore. Kei te maha Triols whakamahia ki te whakanui i te tohu ina te fariiraa i kurupae pūihi.

whakamahi mahi

Ko te transistor me ngōhiko, kua whakahohea te ahupūngao o ratou te whakamahi taahiraa kounga mua te whanaketanga o te katoa hono e te ki te hiko. He uaua ki te whakaaro, kahore waerehe, televisions, rorohiko, waea, me te maha hoki era atu mea. Te p me transistors whakamahia i roto i te hanga nui-tauine kore anake, engari ano hoki i amateurs irirangi me te hikohiko irirangi i roto i o ratou ngā kāinga. Ko reira uaua ki te whakaaro i te poari matatau tāngia ara iahiko, e ka whakahaere i te hangarau matatini, me i nei ki reira e kia rama rorohiko whakahaeretia. Te p me transistors i te tino whānui o ngā tono ngā, na te aroaro o te maha o enei pūrere kāore i tetahi reo irirangi ham te tata whai. Engari kia ratou tono i ngā tupato - te reira taputapu, e mahi ki te ngaohiko, ara, ki te he te reira iti, engari ka waiho i te hopearaa i te iti rawa kino tukunoa'i ture haumaru.
