Kev ua haujlwm thiab lub hom phiaj ntawm inductors

1. Lub luag haujlwm tseem ceeb ntawm ib qho inductor yog kom dhau DC thiab tiv thaiv AC, thiab nws tsuas yog ua lub luag haujlwm hauv kev lim dej, oscillation, ncua sijhawm, thiab notch hauv Circuit Court. Inductive coils muaj qhov cuam tshuam ntawm AC tam sim no, thiab qhov loj ntawm cov nyhuv thaiv yog hu ua inductance XL, ntsuas hauv ohms. Nws txoj kev sib raug zoo nrog inductance L thiab AC zaus f yog XL=2 π fL, thiab inductors tuaj yeem muab faib ua ntau zaus thiab tsawg zaus kuj coils. Tuning thiab zaus xaiv muaj nuj nqi: Lub inductance coil thiab capacitor tuaj yeem txuas rau tib lub sijhawm los tsim LC tuning circuit. Yog hais tias lub ntuj oscillation zaus f0 ntawm lub Circuit Court yog sib npaug rau zaus f ntawm lub teeb liab uas tsis yog AC, ces qhov inductance thiab capacitance ntawm lub Circuit Court kuj sib npaug. Yog li ntawd, electromagnetic zog oscillates rov qab mus rau hauv inductance thiab capacitance, uas yog resonance tshwm sim ntawm LC Circuit Court. Thaum lub sij hawm resonance, qhov inductance thiab capacitance ntawm lub Circuit Court yog sib npaug thiab rov qab, nrog rau qhov inductance ntawm tag nrho cov tam sim no yog qhov tsawg tshaj plaws thiab tam sim no yog qhov loj tshaj plaws (xa mus rau AC teeb liab nrog f="f{{6 }}"). Lub LC resonant circuit muaj lub luag haujlwm ntawm kev xaiv ntau zaus thiab tuaj yeem xaiv lub teeb liab AC nrog qee zaus f.

2. Inductors kuj muaj cov haujlwm xws li lim cov teeb liab, lim suab nrov, stabilizing tam sim no, thiab suppressing electromagnetic cuam tshuam. Hauv cov khoom siv hluav taws xob, nws yog ib qho uas pom cov nplhaib sib nqus uas tsim ib qho inductor nrog cov hlua txuas (cov xov hlau hauv lub cable qhwv ob peb coils ntawm inductance nyob ib ncig ntawm lub nplhaib sib nqus). Lawv feem ntau siv los tiv thaiv kev cuam tshuam hauv cov hluav taws xob hauv hluav taws xob, thiab lub suab nrov nrov muaj kev tiv thaiv zoo. Yog li ntawd, lawv hu ua absorption magnetic rings, feem ntau yog ua los ntawm ferrite cov ntaub ntawv, tseem hu ua ferrite magnetic rings (hu ua magnetic rings). Lub nplhaib sib nqus muaj cov yam ntxwv impedance sib txawv ntawm ntau zaus. Ntawm qhov tsawg zaus, lub impedance yog me me, thiab raws li lub teeb liab zaus nce, impedance ntawm lub nplhaib hlau nplaum yuav nce ntxiv.

3. Kev faib tawm: Raws li seb qhov inductance hloov tau, nws tuaj yeem muab faib ua cov inductance ruaj khov, hloov pauv inductance, thiab nplua-tuning inductance. Raws li seb lub inductance muaj cov tub ntxhais hlau, nws tuaj yeem muab faib ua hollow inductance thiab hlau core inductance.
