Ukuqashelwa kwe-Insulated Layer Gate MOSFETs
Uhlobo lwesango le-insulation lohlobo lwe-MOSFET elibizwa ngokuthi MOSFET (lapha kamuva elibizwa ngokuthi i-MOSFET), elineshevu yekhebula le-silicon dioxide maphakathi ne-voltage yesango kanye nokukhipha umthombo. I-MOSFET iphinde ibe yi-N-channel kanye ne-P-channel izigaba ezimbili, kodwa isigaba ngasinye sihlukaniswe...Funda kabanzi -
Unganquma kanjani ukuthi i-MOSFET yinhle noma yimbi?
Kunezindlela ezimbili zokubona umehluko phakathi kwe-MOSFET enhle nembi: Eyokuqala: hlukanisa ngekhwalithi izinzuzo nezingozi zama-MOSFET Okokuqala sebenzisa i-multimeter R × 10kΩ block (ibhethri elishumekiwe elingu-9V noma i-15V), ipeni elibi (elimnyama) lixhunyiwe. ...Funda kabanzi -
Imibono yokuxazulula ukushisa okukhulu kwama-MOSFET
Angazi uma uthole inkinga, i-MOSFET yenza njengemishini yokushintsha amandla kagesi ngesikhathi sokusebenza kwesinye isikhathi ukushisa okukhulu, ifuna ukuxazulula inkinga yokushisa ye-MOSFET, okokuqala sidinga ukucacisa ukuthi yiziphi izimbangela, ngakho-ke sidinga ukuhlola, ukuze ukuze uthole ukuthi i-pr...Funda kabanzi -
Iqhaza lama-MOSFET kumasekethe
Ama-MOSFET adlala indima ekushintsheni amasekhethi ukulawula umjikelezo wokuvula nokuvala kanye nokuguqulwa kwesignali.Ama-MOSFET angahlukaniswa kabanzi abe izigaba ezimbili: I-N-channel kanye ne-P-channel. Kumjikelezo we-N-channel MOSFET, iphinikhodi ye-BEEP iphakeme ukunika amandla impendulo ye-buzzer, futhi bheka...Funda kabanzi -
Bheka ama-MOSFET
Ama-MOSFET afaka ama-MOSFET kumasekethe adidiyelwe.Ama-MOSFET, njengenye yezinsiza eziyisisekelo emkhakheni we-semiconductor, asetshenziswa kakhulu kumasekethe asezingeni lebhodi kanye nasekwakhiweni kwe-IC.Ukukhipha amanzi kanye nomthombo wama-MOSFET kungaba...Funda kabanzi -
Ukuhlonza okuyisisekelo kwe-MOSFET nokuhlola
1.Ukuhlonza iphinikhodi ye-MOSFET yeJunction Isango le-MOSFET liyisisekelo se-transistor, kanti umsele nomthombo kungumqoqi kanye ne-emitter ye-transistor ehambisanayo. I-multimeter ukuya ku-R × 1k igiya, enamapeni amabili okulinganisa ukumelana nokuya phambili nokuhlehla ...Funda kabanzi -
Izimbangela Nokuvinjelwa Kokwehluleka Kwe-MOSFET
Izimbangela ezimbili eziyinhloko zokwehluleka kwe-MOSFET: Ukuhluleka kwamandla kagesi: okungukuthi, i-voltage ye-BVdss phakathi kwe-drain kanye nomthombo idlula i-voltage elinganiselwe ye-MOSFET futhi ifinyelela umthamo othize, okwenza i-MOSFET ihluleke. I-Gate Voltage Failure: Isango lihlushwa i-voltage engavamile ...Funda kabanzi -
Yini engingayenza ukuze ngilungise i-MOSFET yami eshisisa kabi?
Amasekhethi okuphakela amandla, noma amasekhethi okuphakela amandla emkhakheni wokuqhubela phambili, asebenzisa nakanjani ama-MOSFET, ayizinhlobo eziningi futhi anemisebenzi eminingi. Ukushintsha ukunikezwa kwamandla noma izinhlelo zokusebenza zokuhambisa, kungokwemvelo ukusebenzisa umsebenzi wayo wokushintsha. Ngaphandle kohlobo lwe-N o...Funda kabanzi -
Izici zokuqhuba ze-MOSFET
Ukuqhutshwa kwe-MOSFET kusho ukuthi isetshenziswa njengeswishi, elingana nokuvala iswishi.I-NMOS ibonakala njengeqhuba lapho i-Vgs yeqa inani elilinganiselwe, elisebenza esimweni esinomthombo oxhunywe kudivayisi esekelwe phansi, futhi idinga kuphela isango. ivolumu...Funda kabanzi -
Izimpawu Zokusebenza ze-MOSFET
Eqinisweni, kusukela egameni, amandla e-MOSFET ukuthi angaphinde asebenze lapho okukhiphayo kukhulu, ukuhlukaniswa kwe-MOSFET kuhlukaniswe ngezinhlobo eziningi, okuzungeze izici zokusetshenziswa kwamandla singahlukaniswa zibe ngcono kanye nokuncipha kohlobo, uma...Funda kabanzi -
Ukuhlaziywa kwezizathu zokungasebenzi kwe-MOSFET
Kulesi sigaba ekusetshenzisweni kwemboni, ukusetshenziswa kwempahla ye-adaptha yedivayisi ye-elekthronikhi esezingeni lokuqala. Ezibekwe endaweni yesibili amabhodi omama wekhompyutha, ama-adaptha ekhompyutha, iziqapha ze-LCD nezinye izinto. Ikleliswe endaweni yesithathu inetha yezokuxhumana...Funda kabanzi -
Ukuhlaziywa kwepharamitha kanye nokukalwa kwama-MOSFET
Kunezinhlobo eziningi zamapharamitha ayinhloko we-MOSFET, aqukethe i-DC yamanje, imingcele yamanje ye-AC kanye nemingcele yomkhawulo, kodwa uhlelo lokusebenza olujwayelekile ludinga kuphela ukukhathalela amapharamitha ayisisekelo alandelayo: isimo sokugcwaliswa kwesimo somthombo wokuvuza wamanje we-IDSS pinch-off volt. .Funda kabanzi
