Ua haujlwm ntawm txoj cai ntawm hloov transistorsrauHloov Khoom Siv Hluav Taws Xob
Kev hais nruj me ntsis, cov txheej txheem ntawm kev hloov pauv ntawm qhov kev txiav txim siab los txiav tawm ib qho, tab sis thaum tshuaj xyuas nws cov kev ua haujlwm tsis yooj yim ua ntej. Piv txwv li, thaum lub zog hloov lub raj yog muab rau lossis tawm, peb xav txog nws ib qho kev hloov pauv zoo tagnrho uas ua haujlwm hauv tsuas yog ob lub xeev, ntawm lossis tawm. Tab sis nyob rau hauv kev muaj tiag, lub cooj thiab kaw tawm ntawm hloov pauv hloov pauv yog ob qho txheej txheem nyuaj heev. Ntxiv rau kev ua kom haum lossis tua, muaj cov txheej txheem sib txawv, thiab tom qab ntawd yog thaj chaw ua haujlwm rau thaj chaw ua haujlwm thaum nws ua. Txoj kev ua haujlwm no xav tau kev siv cov sib luag kom daws tau los daws teeb meem, thiab kuv tsis xav qhia nws dhau ntawm no.
Tsuas yog muab tso, nws siv sijhawm rau lub hwj chim hloov raj xa mus rau tig thiab tawm. Feem ntau, lub sij hawm conduction lub raj yog tsuas muab faib rau lub sij hawm kaw ncua sij hawm TSTG (lossis kaw lub sijhawm cia TF.
Hloov cov hluav taws xob muaj kev ua haujlwm tau ua haujlwm, thiab vim cov zis hluav taws xob, lub lim hluav taws xob cia capacitor yuav tsum tau them. Raws li kev them nyiaj tam sim no yog loj, lub nra yuav hnyav (lossis sib npaug rau cov khoom siv luv luv), yog li General hloov fais fab khoom yuav tsum tau txais cov kev ntsuas muag pib. Thaum pib, lub voj voog lub zog yog me me, thiab tom qab ntawd nws maj mam ua kom ib txwm muaj, uas yog lub zog hluav taws xob me me nyob rau thaum pib thiab tom qab ntawd maj mam nce. Thaum pib, qhov chaw ua hauj lwm yog qhov tsis tshua muaj, thiab tom qab ntawd nws maj mam nce mus rau tus nqi ib txwm muaj.
Nruj me ntsis kev hais lus, hloov hom fais fab khoom siv ib txwm ua haujlwm nyob rau hauv lub xeev tsis ruaj khov, thiab ruaj khov yog tsuas yog ib tug txheeb ze. Piv txwv li, cov txheej txheem voltage stability ntawm lub tshuab hloov hluav taws xob nce ntxiv, tom qab kev sib piv, txo lub voj voog lub zog thiab txo cov zis hluav taws xob; Tom qab cov zis voltage txo qis, tom qab kev sib piv thiab kev sib piv, qhov kev piv txwv hluav taws xob dav hlau kom nce lub luag haujlwm puag ncig, yog li nce cov zis voltage. Cov voj voog no rov ua dua tshiab, thiab cov zis hluav taws xob ntawm lub tshuab hloov hluav taws xob yuav ib txwm muaj feem ntau ntawm qhov nruab nrab hluav taws xob ntawm ib qho zaus. Qhov thiaj li -}}}}} hu ua voltage stabilization tsuas yog tias nruab nrab cov zis hluav taws xob yog qhov ruaj khov.
Tam sim no ntws los ntawm thawj kauj ntawm cov hloov pauv hloov tsis yog cov nqi ruaj khov, feem ntau yog Sedtooth nthwv dej tam sim no yog tib yam. Kev tsav tsheb tas li ntawm LED feem ntau hais txog cov kev tawm tsam ruaj khov tam sim no ntawm lub lim tom qab lim, uas yog hais txog tus nqi nruab nrab. Cov tswv yim tam sim no ntawm lub lim yog feem ntau yog Showaloth nthwv dej.
