Shin kun san game da raguwar MOSFETs?

Ma'anoni da Halaye

BAYANI: A ragewaMOSFETnau'i ne na musammanMOSFETwanda ke iya gudanar da wutar lantarki saboda masu ɗaukar kaya sun riga sun kasance a tashar ta lokacin da wutar lantarki ta gate ta kasance sifili ko a cikin takamaiman kewayon. Wannan ya bambanta da haɓakawaMOSFETswanda ke buƙatar takamaiman ƙimar ƙarfin ƙofar don samar da tashar gudanarwa.

Halaye: Nau'in lalacewaMOSFETyana da fa'idodi na babban shigarwar impedance, ƙarancin ɗigogi na halin yanzu da ƙarancin sauya impedance. Waɗannan halayen suna sa ya zama mai ƙima don aikace-aikace da yawa a cikin ƙirar kewaye.

Ƙa'idar Aiki

Ka'idar aiki na raguwaMOSFETsana iya sarrafawa ta hanyar canza wutar lantarki ta ƙofar don sarrafa adadin masu ɗauka a cikin tashar kuma ta haka na yanzu. Ana iya taƙaita tsarin aiki a cikin matakai masu zuwa:

Haramtacciyar jihar: Lokacin da wutar lantarki ta ƙofar ke ƙasa da mahimmancin ƙarfin lantarki tsakanin tashar da tushen, na'urar tana cikin haramtacciyar yanayi kuma babu halin yanzu yana wucewa ta hanyarMOSFET.

Yanayin juriya mara kyau: Yayin da ƙarfin wutar lantarki ya karu, cajin ya fara ginawa a cikin tashar, yana haifar da mummunar juriya. Ta hanyar daidaita wutar lantarki ta ƙofar, ana iya sarrafa ƙarfin juriya mara kyau, don haka sarrafa halin yanzu a cikin tashar.

A JIHAR: Lokacin da ƙarfin ƙofar ƙofar ya ci gaba da karuwa fiye da ƙarfin lantarki mai mahimmanci,MOSFETya shiga cikin jihar ON kuma ana jigilar adadin electrons da ramuka ta hanyar tashar, yana haifar da mahimmancin halin yanzu.

Jikewa: A cikin halin da ake ciki, halin yanzu a cikin tashar ya kai matakin jikewa, wanda a wannan lokacin ci gaba da ƙara ƙarfin ƙofar ba zai ƙara ƙara yawan halin yanzu ba.

Jihar yanke(bayanin kula: bayanin "yankin yankewa" a nan yana iya ɗan bambanta da sauran wallafe-wallafen saboda raguwaMOSFETsko da yaushe gudanar a karkashin wasu yanayi): A karkashin wasu yanayi (misali, wani matsananci canji a ƙofar ƙarfin lantarki), a depletionMOSFETna iya shiga cikin yanayin ƙanƙanta, amma ba a yanke shi gaba ɗaya ba.

Yankunan aikace-aikace

Nau'in lalacewaMOSFETssuna da fa'idodin aikace-aikace a fagage da yawa saboda halayen aikinsu na musamman:

Gudanar da wutar lantarki: Yana amfani da babban shigar da impedance da ƙananan yayyo halaye na yanzu don cimma ingantaccen canjin makamashi a cikin da'irar sarrafa wutar lantarki.

Analog da dijital da'irori: taka muhimmiyar rawa a cikin da'irori na analog da dijital azaman abubuwan canzawa ko tushen yanzu.

Motar tuƙi: daidai iko gudun mota da tuƙi ana gane ta hanyar sarrafa sarrafawa da yanke-kashe naMOSFETs.

Inverter Circuit: A cikin tsarin samar da wutar lantarki na hasken rana da tsarin sadarwar rediyo, a matsayin daya daga cikin mahimman abubuwan da ke cikin inverter, don gane jujjuyawar DC zuwa AC.

Mai sarrafa wutar lantarki: Ta hanyar daidaita girman girman ƙarfin fitarwa, yana gane ingantaccen ƙarfin lantarki kuma yana ba da garantin aikin al'ada na kayan lantarki.

A cikin aikace-aikacen aikace-aikacen, wajibi ne don zaɓar ƙarancin da ya daceMOSFETsamfurin da sigogi bisa ga takamaiman bukatun.

Tun da nau'in ragewaMOSFETsaiki daban da nau'in haɓakawaMOSFETs, suna buƙatar kulawa ta musamman a ƙirar kewaye da haɓakawa.

A taƙaice, nau'in ragewaMOSFET, a matsayin wani muhimmin bangaren lantarki, yana da fa'idodin aikace-aikace masu yawa a fagen lantarki. Tare da ci gaba da ci gaban kimiyya da fasaha da haɓaka buƙatun aikace-aikacen, ayyukansa da iyakokin aikace-aikacen su ma za su ci gaba da haɓakawa da haɓakawa.
