Lub series resonancenyob rau hauv UHV lub zog tuaj yeem pab ntau tus neeg ua haujlwm lub zog ua ntau yam kev ntsuas hluav taws xob yooj yim dua.
Thaum qhov hluav taws xob los yog tam sim no nce mus txog nws tus nqi siab tshaj plaws hauv AC RLC Circuit Court, nws hu ua resonance. Lub reactance ntawm inductance thiab capacitance tshem tawm ib leeg tawm, thiab lub hwj chim muab los ntawm lub hwj chim mov poob ntawm qhov tsis kam. Resonant circuits feem ntau siv hauv xov tooj cua thiab kev sib txuas lus wireless.
Nyob rau hauv physics, muaj ib lub tswv yim hu ua resonance: thaum lub zaus ntawm lub zog tsav tsheb yog sib npaug zos rau lub ntuj zaus ntawm lub system, lub amplitude ntawm yuam kev vibration ntawm lub system yog maximized, thiab qhov tshwm sim no hu ua resonance. Lub resonance nyob rau hauv ib tug Circuit Court txhais tau hais tias thaum lub excitation zaus nyob rau hauv lub Circuit Court yog sib npaug zos rau lub ntuj zaus ntawm lub Circuit Court, lub amplitude ntawm lub electromagnetic oscillation nyob rau hauv lub Circuit Court kuj yuav mus txog nws ncov. Qhov tseeb, resonance thiab resonance qhia tib yam tshwm sim. Qhov tshwm sim no nrog tib lub ntsiab lus muaj cov npe sib txawv hauv ntau qhov chaw.
Ib lub voj voog tsim los ntawm inductor L thiab capacitor C uas tuaj yeem ua suab nrov ntawm ib lossis ob peb zaus yog sib sau ua ke hu ua resonant circuit. Hauv kev tsim hluav taws xob thiab xov tooj cua, feem ntau yuav tsum xaiv cov teeb liab hluav taws xob uas peb xav tau los ntawm ntau lub teeb liab hluav taws xob, thaum tshem tawm lossis lim tawm cov teeb liab hluav taws xob peb tsis xav tau. Yog li ntawd, ib tug xaiv Circuit Court, uas yog ib tug resonant circuit, yog xav tau. Ntawm qhov tod tes, hauv kev tsim hluav taws xob, qee yam kev phom sij xws li overvoltage lossis overcurrent tuaj yeem tshwm sim vim muaj kev cuam tshuam hauv Circuit Court. Yog li ntawd, txoj kev kawm ntawm resonant circuits yog qhov tseem ceeb ntawm ob qho tib si ntawm kev siv thiab nyob rau hauv cov nqe lus ntawm kev txwv lawv kev puas tsuaj.

Lub xov tooj cua siv cov phenomenon ntawm resonance. Thaum tig lub pob qhov rooj ntawm lub xov tooj cua, nws hloov lub ntuj zaus ntawm lub voj voog sab hauv. Tam sim ntawd, ntawm ib qho chaw, qhov zaus ntawm Circuit Court tau sib npaug rau qhov zaus ntawm cov hluav taws xob hluav taws xob uas yav dhau los pom tsis pom nyob hauv huab cua, thiab lawv tau tshwm sim. Lub suab nyob deb tuaj ntawm lub xov tooj cua. Cov suab no yog ib yam khoom ntawm resonance.
Resonant circuits muaj ib tug yam ntxwv uas capacitance yog sib npaug zos rau inductance, thiab yog hais tias lub Circuit Court yog resistive, ces muaj ω L=1/ω C. Txij li thaum LC tau paub tej yam kev mob, zaus point ntawm resonance yuav xam raws li qhov zoo. yam Q=ω L/R. Yog tias qhov zoo tshaj plaws yog 28, ces qhov sib npaug resonant Circuit Court txo qhov tam sim no los ntawm 28 zaug; Yog hais tias nws yog ib tug series resonant circuit, ces qhov voltage tau nce los ntawm 28 lub sij hawm. Yog li tam sim no qhov voltage ntawm lub series resonance point yog qhov siv voltage multiplied los ntawm qhov zoo tshaj plaws. Yog tias cov xwm txheej paub qhia rau koj tias qhov siv hluav taws xob yog qhov siab tshaj tus nqi, ces muab faib ncaj qha; Yog tias cov xwm txheej paub qhia rau koj tias qhov siv hluav taws xob yog qhov muaj txiaj ntsig zoo, tom qab ntawd koj yuav tsum muab qhov ntsuas hluav taws xob los ntawm 1.414 kom tau txais tus nqi siab tshaj.
Cov yam ntxwv ntawm Circuit Court thaum resonance
1. Lub resonant impedance Z0 yog ib tug ntshiab kuj nrog tus nqi tsawg kawg nkaus, uas yog, Z0=R.
2. Tam sim no nyob rau theem nrog lub hwj chim mov voltage, uas yog, φ=ψ u - ψ i=0.
3. Hom tam sim no nce mus txog nws tus nqi siab tshaj plaws, uas yog, I=I0=US/R0, I0 yog hu ua resonant tam sim no.
4. Qhov hluav taws xob siab yuav tshwm sim ntawm ob qho kawg ntawm L thiab C, piv txwv li
UL{{0}}I0XL0=US/R XL0=QUS
UC{{0}}I0XC0=US/R XC0=QUS
Koj puas tuaj yeem pom thaum Q? Thaum 1 teev tsaus ntuj, yog UL0=UCO? Teb Chaws Asmeskas, yog li no series resonance tseem hu ua voltage resonance. Qhov tshwm sim ntawm qhov hluav taws xob siab no yog qhov muaj txiaj ntsig zoo hauv xov tooj cua thiab hluav taws xob engineering, tab sis nws muaj kev phom sij hauv kev tsim hluav taws xob thiab yuav tsum tau tiv thaiv.
