Mayelana nethiyori eyisisekelo yama-transistors afanayo nama-MOSFET: Okokuqala, ama-transistors anenani lokushisa elibi elichazayo, okusho ukuthi, lapho izinga lokushisa le-transistor ngokwalo likhuphuka, ukumelana nokumelana kuzoba kuncane. Okwesibili, ama-MOSFET anenani lezinga lokushisa elilungile lokuchasisa ngokungafani nama-transistors, okusho ukuthi lapho izinga lokushisa likhuphuka, ukumelana nokumelana kuzokhuphuka kancane.
Uma kuqhathaniswa nama-transistors, ama-MOSFET empeleni afaneleka kakhulu ukulinganisa okwamanje kumasekhethi wamandla ahambisanayo. Ngakho-ke uma okwamanje kusekethe yokuphakelwa kwamandla kukukhulu, sivame ukuncoma ukusetshenziswa kwama-MOSFET afanayo we-shunt. Uma sikhetha ama-MOSFETs ukulinganisa okwamanje, futhi ngenye yendlela i-current edlula enye indlela ye-MOSFET current, i-current ye-MOSFET ebangelwa ukushisa kwama-MOSFET amakhulu, okuzoholela ekutheni ukumelana nokucisha kuba kukhudlwana. , ukunciphisa ukwehla kwamandla; Ama-MOSFET asuselwe kumehluko wamanje ukuze alungise njalo, futhi ekugcineni abone ibhalansi yamanje phakathi kwakho kokubiliAma-MOSFET.
Enye yezinto okudingeka siyiqaphele: ama-transistors nawo angaxhunywa ngokuhambisana ukuze aqedele ukugeleza kwezimpahla zamanje, kodwa-ke futhi udinga ukususelwa kusisekelo se-resistor yochungechunge lwedrayivu ukuze ubhekane nebhalansi yamanje ngayinye. i-transistor ehambisanayo phakathi kwenkinga.
Izinkinga ezijwayelekile zokuxhumeka kwe-transistor parallel:
(1), isango le-transistor ngayinye alikwazi ukuxhunywa ngokuqondile ku-resistor ngayinye ye-drive ochungechungeni ukuze kuqhutshwe idrayivu, ukuze kugwenywe ukuzulazula.
(2), ukukhohlisa i-transistor ngayinye(MOSFET)isikhathi esivulekile nesikhathi sokuvala ukuze kugcinwe ukungaguquguquki, ngoba uma kungalingani, eyokuqala yokuvula ipayipi noma ukuvala ipayipi izobhujiswa ngenxa yokungena kwamanje ngokweqile.
(3), futhi ekugcineni, singathanda ukwazi umthombo we-transistor ngayinye ochungechungeni nge-resistor elinganayo, yebo, akudingekile ukwenza, uma kwenzeka.
U-Olueky usephenduke i-ejenti ehamba phambili nekhula ngokushesha e-Asia ngokuthuthukiswa kwemakethe okunolaka nokuhlanganiswa kwezinsiza okusebenzayo. Ukuba yi-ejenti ebaluleke kakhulu emhlabenikwe olukeyumgomo.
