Ungakhetha kanjani umjikelezo womshayeli ofaneleka kakhulu we-MOSFET?
Ohlelweni lokushintshwa kwamandla kagesi kanye nolunye uhlelo lokuklama isistimu yokuphakelwa kwamandla, abaklami bohlelo bazonaka kakhudlwana inani lemingcele emikhulu ye-MOSFET, efana ne-on-off resistor, i-voltage yokusebenza enkulu, ukugeleza kwamandla amakhulu. Nakuba le nto ibalulekile, kubhekwa...Funda kabanzi -
MOSFET Driver Circuit Izidingo
Ngabashayeli banamuhla be-MOS, kunezidingo ezimbalwa ezingavamile: 1. Isicelo se-voltage ephansi Lapho isicelo se-5V switching power supply, ngalesi sikhathi uma ukusetshenziswa kwesakhiwo se-totem pole yendabuko, ngenxa yokuthi i-triode ibe yi-0.7V kuphela ukulahlekelwa phezulu naphansi, okuholela ...Funda kabanzi -
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 -
