Nyob rau hauv lub ntiaj teb no technology-tsav, hluav taws xob circuits tau dhau los ua ib feem tseem ceeb ntawm peb lub neej niaj hnub.Los ntawm cov xov tooj smartphones mus rau hybrid tsheb, cov circuits no muaj txhua yam, pab txhawb peb txoj kev nplij siab thiab kev tsim khoom.Txawm li cas los xij, ntawm qhov kev xav tau muab rau peb los ntawm cov khoom siv hluav taws xob, muaj ib qho hluav taws xob phem: suab nrov.Ib yam li cov qhua uas tsis xav tau, suab nrov cuam tshuam kev sib haum xeeb hauv cov hluav taws xob hluav taws xob, feem ntau ua rau kev ua haujlwm tsis zoo.Hmoov zoo, muaj cov cuab yeej muaj zog ntawm peb cov khoom pov tseg - inductors - uas tuaj yeem cuam tshuam cov hluav taws xob chaos hu ua suab nrov.
Ua ntej peb delve rau hauv lub luag hauj lwm ntawm inductors nyob rau hauv lub suab nrov suppression, nws yog ib qho tseem ceeb kom nkag siab lub hauv paus chiv keeb thiab qhov tshwm sim ntawm lub suab nrov nyob rau hauv hluav taws xob circuits.Lub suab nrov, hauv cov ntsiab lus no, yog hais txog cov cim hluav taws xob tsis xav tau uas cuam tshuam nrog kev ua haujlwm zoo ntawm cov khoom siv hluav taws xob.Ib qho ntawm cov teeb meem tseem ceeb tom qab lub suab nrov yog electromagnetic cuam tshuam (EMI), uas tuaj yeem tawm los ntawm ob qho tib si sab hauv thiab sab nraud.
Cov kev cuam tshuam no tuaj yeem suav nrog cov kab hluav taws xob, cov khoom siv nyob sib ze, xov tooj cua zaus hluav taws xob, thiab xob laim.Thaum lub suab nrov nkag mus rau hauv Circuit Court, nws cuam tshuam cov teeb liab kev ncaj ncees, cuam tshuam cov ntaub ntawv xa mus, thiab tuaj yeem ua rau tag nrho lub cev tsis ua haujlwm.Yog li ntawd, qhov kev xav tau ntawm kev siv suab nrov nrov tau dhau los ua qhov tseem ceeb.
Inductors, feem ntau saib tsis tau hauv thaj tsam ntawm cov khoom siv hluav taws xob, ua lub luag haujlwm tseem ceeb hauv kev txo cov teebmeem ntawm lub suab nrov.Ib qho tseem ceeb ntawm cov hluav taws xob circuits, ib qho inductor khaws cov hluav taws xob hluav taws xob hauv qhov chaw sib nqus thaum tam sim no ntws los ntawm nws.Lub zog khaws cia no tuaj yeem siv ntxiv los tiv thaiv lub suab nrov thiab tiv thaiv nws qhov tsis zoo.
Kev txwv tsis pub muaj suab nrov feem ntau suav nrog kev siv cov lim dej qis, uas tso cai rau cov teeb liab tsawg dhau los thiab ua kom lub suab nrov nrov.Lub inductor cov yam ntxwv tseem ceeb, xws li inductance thiab impedance, ua rau nws zoo tagnrho rau daim ntawv thov no.Nrog nws lub peev xwm los cuam tshuam cov kev hloov pauv sai hauv tam sim no, inductors ua qhov cuam tshuam rau lub suab nrov nrov cuam tshuam, tso cai rau qhov huv thiab ruaj khov tam sim no xa mus rau cov khoom rhiab heev.
Daim ntawv thov ntawm Inductors nyob rau hauv Noise Suppression:
1.Inductors pom ntau daim ntawv thov hauv kev siv suab nrov thoob plaws ntau yam khoom siv hluav taws xob.Lawv feem ntau yog siv nyob rau hauv lub hwj chim mov circuits, qhov twg lawv du tawm voltage waveforms, txo ripple suab nrov tshwm sim los ntawm ceev ceev hloov nyob rau hauv lub hwj chim mov signals.Los ntawm kev tswj cov input voltage, inductors txhim khu kev ruaj ntseg thiab kev ntseeg siab ntawm cov tshuab hluav taws xob.
2.Ib qho tseem ceeb ntawm daim ntawv thov ntawm inductors nyob rau hauv kev tiv thaiv rhiab analog circuits, xws li suab amplifiers, los ntawm high-frequency suab cuam tshuam.Los ntawm kev ua tib zoo xaiv cov inductors nrog cov txiaj ntsig tsim nyog, engineers tuaj yeem xyuas kom tshem tawm cov suab nrov tsis xav tau thaum khaws cia qhov kev ncaj ncees ntawm thawj lub suab teeb liab.
Lub ntiaj teb ntawm cov hluav taws xob hluav taws xob yog qhov chaw sib ntaus sib tua ntawm kev txiav txim thiab chaos, nrog lub suab nrov nrov ntawm txhua lub ces kaum.Hauv qhov kev tawm tsam tsis tu ncua no, inductors tshwm sim los ua tus phab ej uas tsis muaj suab npe, ua lub luag haujlwm tseem ceeb hauv kev tawm suab nrov.Los ntawm kev nqis peev rau lawv cov khoom tshwj xeeb, cov khoom txo qis no tso cai rau peb los tswj cov hluav taws xob chaos thiab qhib lub peev xwm ntawm peb cov khoom siv hluav taws xob.
Raws li kev siv thev naus laus zis txuas ntxiv mus ntawm qhov tsis tau pom dua ua ntej, lub luag haujlwm ntawm inductors hauv kev tawm suab nrov yuav tsuas loj hlob hauv qhov tseem ceeb.Cov kws tsim qauv thiab cov kws tsim qauv yuav txuas ntxiv siv lawv lub zog los ua kom muaj kev ntseeg siab dua, txhim kho kev ua tau zoo, thiab lub ntiaj teb ntsiag to hluav taws xob rau peb txhua tus.Yog li, lwm zaus koj pom koj tus kheej nyob rau hauv qhov kev xav ntawm niaj hnub thev naus laus zis, cia kev xav rau cov inductors ntsiag to ua haujlwm tom qab qhov xwm txheej kom cov hluav taws xob chaos ntawm bay.
