MOSFET da'irar ana amfani da su a cikin kayan lantarki, kuma MOSFET tana nufin Metal-Oxide-Semiconductor Field-Effect Transistor. Zane da aikace-aikacen da'irori na MOSFET sun rufe fage da yawa. A ƙasa akwai cikakken nazarin da'irori na MOSFET:
I. Asalin Tsarin da Ƙa'idar Aiki na MOSFETs
1. Tsarin asali
MOSFETs sun ƙunshi mafi yawan na'urorin lantarki guda uku: ƙofar (G), tushen (S), da magudanar ruwa (D), tare da rufin rufin oxide na ƙarfe. Dangane da nau'in tashar gudanarwa, MOSFETs an rarraba su zuwa N-channel da nau'ikan tashar P. Dangane da tasirin wutar lantarki na kofa akan tashar gudanarwa, ana iya raba su zuwa yanayin haɓakawa da yanayin ragewa MOSFETs.
2. Ƙa'idar Aiki
Ka'idar aiki ta MOSFET ta dogara ne akan tasirin filin lantarki don sarrafa sarrafa kayan aikin semiconductor. Lokacin da ƙarfin wutar lantarki ya canza, yana canza rarraba cajin akan saman semiconductor a ƙarƙashin ƙofar, wanda ke sarrafa faɗin tashar gudanarwa tsakanin tushen da magudanar ruwa, don haka yana daidaita magudanar ruwa. Musamman, lokacin da ƙarfin wutar lantarki na ƙofar ya wuce ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun tashoshi, tashoshi mai ɗaukuwa yana buɗewa akan saman semiconductor, yana ba da izinin gudanarwa tsakanin tushen da magudanar ruwa. Sabanin haka, idan tashar ta ɓace, an yanke tushen da magudanar ruwa.
II. Aikace-aikace na MOSFET Circuits
1. Amplifier kewaye
MOSFETs za a iya amfani da su azaman amplifiers ta daidaita wutar lantarki ta ƙofar don sarrafa riba na yanzu. Ana amfani da su a cikin sauti, mitar rediyo, da sauran da'irori na haɓakawa don samar da ƙaramar amo, ƙarancin wutar lantarki, da haɓakar riba mai yawa.
2. Canjawa Da'irori
MOSFETs ana amfani da su sosai azaman masu sauyawa a cikin da'irori na dijital, sarrafa wutar lantarki, da direbobin motoci. Ta hanyar sarrafa wutar lantarkin ƙofar, mutum zai iya kunnawa ko kashewa cikin sauƙi. A matsayin abubuwa masu canzawa, MOSFETs suna da fa'idodi kamar saurin sauyawa, ƙarancin wutar lantarki, da da'irar tuƙi masu sauƙi.
3. Analog Canja Da'irori
A cikin da'irori na analog, MOSFETs kuma na iya aiki azaman masu sauya analog. Ta hanyar daidaita ƙarfin wutar lantarki na ƙofar, za su iya sarrafa yanayin kunnawa / kashewa, ba da damar sauyawa da zaɓin siginar analog. Irin wannan aikace-aikacen ya zama ruwan dare a sarrafa sigina da siyan bayanai.
4. Dabarun Hankali
MOSFETs kuma ana amfani da su sosai a cikin da'irar dabaru na dijital, kamar ƙofofin dabaru (DA, KO ƙofofin, da sauransu) da rukunin ƙwaƙwalwar ajiya. Ta haɗa MOSFETs da yawa, ana iya ƙirƙirar tsarin da'irar dabaru na dijital.
5. Wuraren Gudanar da Wuta
A cikin da'irar sarrafa wutar lantarki, MOSFETs za a iya amfani da su don sauya wutar lantarki, zaɓin wutar lantarki, da daidaita wutar lantarki. Ta hanyar sarrafa yanayin kunnawa/kashe na MOSFET, ana iya samun ingantaccen gudanarwa da sarrafa iko.
6. Masu Canzawa na DC-DC
Ana amfani da MOSFETs a cikin masu juyawa DC-DC don canjin makamashi da ka'idojin wutar lantarki. Ta hanyar daidaita sigogi kamar zagayowar aiki da mitar sauyawa, ana iya samun ingantaccen jujjuyawar wutar lantarki da ingantaccen fitarwa.
III. Mabuɗin Zane-zane na MOSFET
1. Ƙofar Wutar Lantarki
Wutar lantarkin ƙofar shine maɓalli mai mahimmanci don sarrafa motsin motsin MOSFET. Lokacin zayyana da'irori, yana da mahimmanci don tabbatar da daidaito da daidaiton ƙarfin lantarki na ƙofar don guje wa lalacewar aiki ko gazawar da'ira saboda jujjuyawar wutar lantarki.
2. Magudanar Ƙarfin Halin Yanzu
MOSFETs suna haifar da takamaiman adadin magudanar ruwa yayin aiki. Don kare MOSFET da inganta aikin kewayawa, yana da mahimmanci a iyakance magudanar ruwa ta hanyar zayyana da'irar yadda ya kamata. Ana iya samun wannan ta hanyar zaɓar ƙirar MOSFET daidai, saita ƙarfin ƙarfin ƙofa, da amfani da juriya masu dacewa.
3. Tsantsar Zazzabi
Ayyukan MOSFET yana tasiri sosai ta yanayin zafi. Zane-zane ya kamata a yi la'akari da tasirin zafin jiki akan aikin MOSFET, kuma yakamata a ɗauki matakai don haɓaka kwanciyar hankali, kamar zaɓar samfuran MOSFET tare da kyakkyawar juriyar zafin jiki da amfani da hanyoyin sanyaya.
4. Keɓewa da Kariya
A cikin hadaddun da'irori, ana buƙatar matakan keɓewa don hana tsangwama tsakanin sassa daban-daban. Don kare MOSFET daga lalacewa, ya kamata a aiwatar da da'irori na kariya kamar kariyar wuce gona da iri.
A ƙarshe, MOSFET da'irori wani muhimmin sashi ne na aikace-aikacen da'irar lantarki. Kyakkyawan ƙira da aikace-aikacen da'irori na MOSFET na iya cika ayyukan da'ira daban-daban kuma sun cika buƙatun aikace-aikace daban-daban.
