Hais txog MOSFET tsav tsheb

Nyob rau hauv sib piv rau dual spinning siv lead ua triode, nws yog feem ntau xav tias ua tusMOSFETkev coj tsis siv hluav taws xob ntws, tab sis tsuas yog yuav tsum muaj qhov hluav taws xob GS kom siab dua li tus nqi. Nws yog ib qho yooj yim los ua qhov no, peb feem ntau xav tau tus nqi.

Rau cov qauv ntawm MOSFET, peb tuaj yeem nrhiav tau hauv GS, GD, yuav muaj qee qhov kab mob parasitic capacitance, thiab MOSFET tsav, qhov tseeb, yog kom them nqi thiab tso tawm capacitance. Rau kev them nyiaj ntawm cov capacitors peb tsuas xav tau ib qho tam sim no txaus, vim hais tias lub capacitor nyob rau hauv lub sij hawm them nyiaj yog sib npaug rau lub capacitor raws li ib tug luv luv Circuit Court, lub sij hawm tam sim no tam sim no yuav siab dua li cov xwm txheej dav dav. Yog li ntawd, peb mam li xaiv los yog tsim MOSFET tsav Circuit Court kev pab cuam, thawj yam uas yuav tsum tau them sai sai rau qhov loj ntawm instantaneous short-circuit tam sim no muab tau.

Qhov thib ob, NMOS, uas yog dav siv rau high-end tsav, yuav tsum cia lub rooj vag voltage tshaj qhov voltage thaum nws ua. High-end tsav MOSFET nyob rau hauv lub sij hawm, qhov voltage thiab ntws voltage loj yog tib yam, yog li lub sij hawm no lub rooj vag voltage yuav tsum yog 4V los yog 10V ntau tshaj Vcc. Yog hais tias nyob rau hauv tib lub cev, xav tau ntau tshaj Vcc rooj vag voltage, koj yuav tsum tau tshwj xeeb hauv kev tswj cov voltage Circuit Court. Muaj ntau lub tshuab tsav tsheb yog tsim los ntawm cov twj tso kua mis, nws yuav tsum tau muab sau tseg tias peb yuav tsum xaiv qhov tsim nyog sab nraud capacitor, thiaj li kom tau txais qhov luv luv tam sim no los tsav MOSFET.

Olueky core pab neeg tshwj xeeb hauv cov khoom, lub hauv paus hauv Shenzhen. Main:MOSFET, MCU, IGBT thiab lwm yam khoom siv. Cov khoom tseem ceeb ntawm tus neeg sawv cevWINSOK, Cwm. cov khoom siv dav siv hauv kev ua tub rog, kev tswj hwm kev lag luam, lub zog tshiab, khoom siv kho mob, 5G, Internet ntawm Yam, ntse tsev, thiab ntau yam khoom siv hluav taws xob. Kev cia siab rau qhov zoo ntawm thawj tus neeg sawv cev thoob ntiaj teb, raws li kev lag luam hauv Suav teb. Siv qhov zoo ntawm cov kev pabcuam zoo meej rau cov neeg siv khoom los qhia txhua yam ntawm cov khoom siv hluav taws xob siab tshaj plaws, los pab cov tuam txhab tsim cov khoom zoo thiab muab kev pabcuam zoo meej.
