Ma MOSFET amphamvu kwambiri (metal-oxide-semiconductor field-effect transistors) amagwira ntchito yofunika kwambiri paukadaulo wamakono wamagetsi.Chipangizochi chakhala chofunikira kwambiri pamagetsi amagetsi komanso kugwiritsa ntchito mphamvu zambiri chifukwa chakuchita bwino komanso kugwiritsa ntchito mosiyanasiyana.Nkhaniyi ifotokozanso za mfundo zogwirira ntchito za ma MOSFET amphamvu kwambiri kuti apatse mainjiniya ndi okonda zamagetsi kuti amvetsetse mwatsatanetsatane komanso mozama.
Kodi MOSFET yamphamvu kwambiri ndi chiyani?
MOSFET yamphamvu kwambiri ndi chosinthira cha semiconductor chomwe chimatha kunyamula ma voltage apamwamba komanso apamwamba.Lili ndi magawo atatu akuluakulu: Gwero, Kukhetsa ndi Chipata.Chipatacho chimasiyanitsidwa ndi gwero ndikukhetsa ndi gawo lochepa la oxide, lomwe ndi gawo la "oxide" la kapangidwe ka MOS.
Momwe mphamvu ya MOSFET imagwirira ntchito
Mfundo yogwira ntchito ya MOSFET yamphamvu kwambiri imachokera pakuwongolera magetsi.Pamene magetsi akutsogolo akugwiritsidwa ntchito pakati pa chipata ndi gwero, njira yowonongeka imapangidwa muzinthu za semiconductor pansi pa chipata, kulumikiza gwero ndi kukhetsa, kulola kuti panopa kuyenda.Mwa kusintha voteji pachipata, tingathe kulamulira conductive njira conductive, potero kukwaniritsa kulamulira bwino panopa.
Dongosolo lamagetsi lamagetsi ili limapatsa MOSFET maubwino ambiri, kuphatikiza kutsika kwapang'onopang'ono, kusinthika kothamanga kwambiri komanso kusokoneza kwambiri.Makhalidwewa amapangitsa ma MOSFET amphamvu kwambiri kukhala oyenera kugwiritsa ntchito zomwe zimafunikira kuchita bwino komanso kuyankha mwachangu.
Ubwino wa ma MOSFET amphamvu kwambiri
Kuchita bwino kwambiri: Chifukwa chokana kukana, ma MOSFET amphamvu kwambiri amagwiritsa ntchito mphamvu zochepa m'boma, motero amawongolera magwiridwe antchito.
Kusintha mwachangu: Ma MOSFET amphamvu kwambiri amatha kuzimitsa kwakanthawi kochepa kwambiri, komwe ndikofunikira pakuwongolera pafupipafupi komanso kuwongolera kwapang'onopang'ono (PWM).
Kugwira ntchito pafupipafupi: Amatha kugwira ntchito pama frequency apamwamba, kupangitsa otembenuza mphamvu kukhala ang'onoang'ono komanso opambana.
Malo ofunsira
Ma MOSFET amphamvu kwambiri amagwiritsidwa ntchito kwambiri pazida zosiyanasiyana zamagetsi zamagetsi, monga magalimoto amagetsi, magetsi osinthika, magetsi osinthira, ndi zida zamagetsi zamagetsi.
Fotokozerani mwachidule
Ma MOSFET amphamvu kwambiri akhala gawo lofunikira kwambiri paukadaulo wamakono wamagetsi chifukwa cha magwiridwe antchito awo abwino komanso magwiridwe antchito osinthika.Pomvetsetsa mfundo zake zogwirira ntchito ndi zopindulitsa, mainjiniya ndi okonza amatha kugwiritsa ntchito bwino chipangizo champhamvu ichi kuti abweretse mayankho amagetsi amphamvu komanso odalirika padziko lonse lapansi.Izi sizimangolimbikitsa kupita patsogolo kwaukadaulo, komanso kumabweretsa mwayi ku moyo wathu watsiku ndi tsiku.
