Kodi pali kusiyana kotani pakati pa MOSFETs ndi Triodes akagwiritsidwa ntchito ngati masiwichi?

MOSFET ndi Triode ndizodziwika kwambiri pakompyuta, zonse zingagwiritsidwe ntchito ngati zosinthira zamagetsi, komanso nthawi zambiri kusinthanitsa kugwiritsa ntchito masiwichi, ngati chosinthira kugwiritsa ntchito,MOSFETndi Triode ali ndi zofanana zambiri, palinso malo osiyanasiyana, kotero awiriwa ayenera kukhala momwe angasankhire?

 

Triode ili ndi mtundu wa NPN ndi mtundu wa PNP.MOSFET ilinso ndi N-channel ndi P-channel.Mapini atatu a MOSFET ndi chipata G, drain D ndi source S, ndipo mapini atatu a Triode ndi base B, osonkhanitsa C ndi emitter E. Kodi pali kusiyana kotani pakati pa MOSFET ndi Triode?

 

 

N-MOSFET ndi NPN Triode amagwiritsidwa ntchito ngati mfundo yosinthira

 

(1) Kuwongolera kosiyanasiyana

Triode ndi zida zowongolera zamtundu wamakono, ndipo MOSFET ndi zida zowongolera voteji, Triode pazofunikira za voliyumu ya mbali yowongolera ndizotsika, nthawi zambiri 0.4V mpaka 0.6V kapena kupitilira apo zitha kuzindikirika Triode pa, posintha malire oyambira. resistor panopa akhoza kusintha maziko panopa. MOSFET imayendetsedwa ndi voltage, voteji yomwe imafunikira pakuwongolera nthawi zambiri imakhala pafupifupi 4V mpaka 10V, ndipo machulukitsidwe akafika, voteji yofunikira imakhala pafupifupi 6V mpaka 10V. Poyang'anira zochitika zotsika zamagetsi, kugwiritsa ntchito Triode ngati chosinthira, kapena Triode ngati chowongolera chowongolera MOSFET, monga ma microcontrollers, DSP, PowerPC ndi mapurosesa ena a I / O doko ndi otsika, 3.3V kapena 2.5V okha. , ambiri sadzakhala mwachindunji kulamuliraMOSFET, voteji m'munsi, MOSFET sangakhale conduction kapena kukana kwamkati kwa mowa waukulu wamkati Pankhaniyi, ulamuliro wa Triode umagwiritsidwa ntchito.

 

(2) Kusintha kosiyanasiyana kolowera

Kulowetsedwa kwa Triode ndikochepa, kulowetsedwa kwa MOSFET ndi kwakukulu, mphamvu ya mphambano ndi yosiyana, mphamvu ya Triode yolumikizana ndi yaikulu kuposa MOSFET, zomwe zimachitika molingana ndi MOSFET kukhala mofulumira kuposa Triode;MOSFETkukhazikika kwabwinoko, ndi kokondakita yambiri, phokoso laling'ono, kukhazikika kwamafuta kuli bwino.

Kukaniza kwamkati kwa MOSFET ndikocheperako, ndipo kutsika kwamagetsi a Triode paboma kumakhala kosasintha, pakanthawi kochepa, nthawi zambiri amagwiritsa ntchito Triode, ndikugwiritsa ntchito MOSFET ngakhale kukana kwamkati kuli kochepa kwambiri, koma komweko ndi kwakukulu, kutsika kwamagetsi kulinso. chachikulu kwambiri.
