Ii-MOSFET ezinamandla aphezulu (i-metal-oxide-semiconductor field-effect transistors) zidlala indima ebalulekileyo kubunjineli be-elektroniki bale mihla. Esi sixhobo siye saba yinto eyimfuneko kumbane we-elektroniki kunye nezicelo zamandla aphezulu ngenxa yokusebenza kwayo okugqwesileyo kunye nezicelo ezahlukeneyo. Eli nqaku liza kuphonononga imigaqo yokusebenza yee-MOSFET ezinamandla aphezulu ukunika iinjineli kunye nabantu abathanda izinto zombane ukuqonda okubanzi nokunzulu.
Yintoni i-MOSFET yamandla aphezulu?
I-MOSFET yamandla aphezulu sisitshixo se-semiconductor esikwaziyo ukuphatha i-voltage ephezulu yangoku kunye nephezulu. Iqulathe iinxalenye ezintathu eziphambili: Umthombo, iDrain kunye neSango. Isango lilodwa kumthombo kwaye likhuphe ngoluhlu oluncinci lwe-oxide, oluyinxalenye ye "oxide" yesakhiwo seMOS.
Amandla aphezulu kangakanani asebenza i-MOSFET
Umgaqo osebenzayo we-MOSFET wamandla aphezulu usekwe kulawulo lwendawo yombane. Xa i-voltage yangaphambili isetyenziswe phakathi kwesango kunye nomthombo, i-channel conductive yenziwe kwizinto eziphathekayo ze-semiconductor phantsi kwesango, ukudibanisa umthombo kunye nokucima, ukuvumela ukuba kubekho ukuhamba ngoku. Ngokulungelelanisa i-voltage yesango, sinokulawula ukuqhutyelwa kwesiteshi sokuqhuba, ngaloo ndlela sifezekise ulawulo oluchanekileyo lwangoku.
Le ndlela yokulawula intsimi yombane inika i-MOSFET iingenelo ezininzi, kubandakanya ukuxhathisa okuphantsi, amandla okutshintsha ngesantya esiphezulu kunye nokuphazamiseka kokungena okuphezulu. Ezi mpawu zenza ii-MOSFETs zamandla aphezulu zilungele ngakumbi izicelo ezifuna ukusebenza kakuhle kunye nokuphendula ngokukhawuleza.
Izinto ezilungileyo zamandla aphezulu eMOSFETs
Ukusebenza okuphezulu: Ngenxa yokuxhathisa okuphantsi, ii-MOSFETs zamandla aphezulu zisebenzisa amandla amancinane kakhulu kurhulumente, ngaloo ndlela ziphucula ukusebenza kakuhle.
Ukutshintsha ngokukhawuleza: I-MOSFET enamandla amakhulu inokutshintsha ukusuka kwithuba elifutshane kakhulu lexesha, nto leyo ibaluleke kakhulu kukuguqulwa kwamaza kunye nolawulo lwe-pulse-width modulation (PWM).
Ukusebenza kwe-high-frequency: Bayakwazi ukusebenza kwii-frequencies eziphezulu, okwenza abaguquli bamandla bancinci kwaye basebenze ngakumbi.
Iindawo zesicelo
Ii-MOSFET ezinamandla amakhulu zisetyenziswa ngokubanzi kwizixhobo zombane ezinamandla amakhulu, njengezithuthi zombane, iinkqubo zamandla ahlaziyekayo, umbane otshintshayo, kunye nezixhobo ezizisebenzelayo kwimizi-mveliso.
Shwankathela
Ii-MOSFET ezinamandla aphezulu ziye zaba yinxalenye ebalulekileyo yetekhnoloji ye-elektroniki yale mihla ngenxa yokusebenza kwazo okugqwesileyo kunye nezicelo ezibhetyebhetye. Ngokuqonda imigaqo yayo yokusebenza kunye neenzuzo, iinjineli kunye nabayili banokusebenzisa ngcono esi sixhobo sinamandla ukuzisa izisombululo ezisebenzayo nezithembekileyo ze-elektroniki kwihlabathi. Oku akukhuthazi kuphela inkqubela phambili yezobuchwepheshe, kodwa kuzisa lula kubomi bethu bemihla ngemihla.
