Iimpawu zokuSebenza zeMOSFET

Ngapha koko, ukusuka kwigama, amandla e-MOSFET kukuba inokusebenza kwakhona xa imveliso yangoku inkulu, ulwahlulo lwe-MOSFET lwahlulahlulwe lwaba ziindidi ezininzi, ezithi malunga neempawu zokusetyenziswa kwamandla sinokwahlulwa sibe siphuculo kunye nokuncipha kohlobo, ukuba ngokungqinelana nejelo lokukhetha amagama anokwahlulwa kudidi lwe-N-channel kunye nodidi lwe-P-channel.
Ii-MOSFET zisetyenziswa ikakhulu njengokutshintsha kwenkqubo kwiinkqubo ezikhupha amandla. Ukuba songeza enye i-voltage phakathi kwesango kunye nomthombo we-N-channel MOSFET, iya kuvula iswitshi yayo yamandla. Nje ukuba umbane uvuliwe, ngoku uqukuqela ngokutshintsha kwamandla ukusuka kumbhobho ukuya kumthombo. Kukho ukuchasana kwangaphakathi phakathi kombhobho kunye nomthombo, esiwubiza ngokubanzi i-RDS (ON) kwi-resistor. Kufuneka icace into yokuba isango le-MOSFET eneneni sisixhobo esineempawu eziphezulu zokuphazamiseka, ngoko ke kufuneka songeze enye i-voltage esangweni. Xa i-voltage phakathi komthombo kunye nesango i-zero, umbane wombane uyacima kwaye ukuhamba kwangoku kuphelisa ngokwesixhobo. Nangona isixhobo sicinyiwe ixesha elide, kusekho isixa esincinci sangoku, esibizwa ngokuba yi-IDSS evuzayo yangoku.
NgokubaIi-MOSFETslelinye lawona malungu abalulekileyo enkqubo yolawulo lombane, ukukhetha iMOSFET efanelekileyo kudlala indima ebalulekileyo kwimpumelelo yenkqubo yoyilo iyonke. Kuphela ngokukwazi kakuhle iintlobo zee-MOSFET kunye neempawu zazo eziphambili, abaqulunqi banokukhetha i-MOSFET efanelekileyo kuyilo oluthile.

I-MOSFET yamandla iklasi esetyenziswa ngokuxhaphakileyo yezixhobo zamandla, igama elipheleleyo le-Chinese yi-metal oxide semiconductor field effect tube. Iyeyesixhobo sokukhupha amandla, ngokukodwa ihlanganiswe ngesinyithi, i-oxide kunye nezixhobo ze-semiconductor. Ngoko yintoni amandlaI-MOSFET?

Ngophuhliso lwemarike olusebenzayo kunye nokuhlanganiswa kwezibonelelo okusebenzayo,olukeyibe yenye yezona arhente zibalaseleyo nezikhula ngokukhawuleza eAsia, kwaye yinjongo eqhelekileyo ka olukey ukuba yeyona arhente ixabisekileyo kwihlabathi. Ukutyhubela iminyaka, inkampani olukey ukusinda ngetyala, ukubambelela "kwinqanaba lokuqala, inkonzo kuqala" injongo kunye namashishini amaninzi akumgangatho ophezulu ekhaya nakwamanye amazwe, umzi-mveliso wokuqala ukuseka ubudlelwane obuhle bokusebenza, kunye neminyaka emininzi yamava omsebenzi ekusasazeni. , ngetyala elihle, inkonzo ebalaseleyo, kwaye wafumana ukuthenjwa kunye nenkxaso ngokubanzi.
