Series resonant Circuit Court
Hauv AC Circuit Court nrog resistor R, inductor L, thiab capacitor C Cheebtsam, qhov voltage ntawm ob qhov kawg ntawm lub Circuit Court yog feem ntau sib txawv nyob rau hauv theem ntawm tam sim no nyob rau hauv nws. Yog tias qhov tsis muaj lossis lub zog zaus ntawm cov khoom siv hluav taws xob (L lossis C) raug hloov kho, lawv tuaj yeem ua kom muaj tib theem, thiab tag nrho cov Circuit Court zoo nkaus li tiv taus. Thaum lub voj voog mus txog lub xeev no, nws hu ua resonance. Nyob rau hauv lub xeev resonant, tag nrho impedance ntawm Circuit Court ncav cuag los yog kwv yees nws cov nqi siab tshaj plaws. Muaj ob hom kev sib txuas ntawm Circuit Court:series resonancethiab parallel resonance. Kev tshawb fawb thiab kev siv thev naus laus zis yuav tsum tau siv tag nrho cov yam ntxwv ntawm resonance thaum tseem tiv thaiv kev puas tsuaj nws yuav ua rau.
Cov yam ntxwv ntawm series resonant circuit:
a. Lub Circuit Court impedance Z yog qhov tsawg tshaj plaws thiab ntshiab tsis kam, thiab Z=R
b. Tam sim no kuv nyob rau hauv Circuit Court mus txog nws qhov siab tshaj plaws tus nqi thiab yog tib yam li lub hwj chim mov voltage
Qhov tam sim no uas tshwm sim thaum lub voj voog dhau los ntawm cov resonance yog hu ua resonance tam sim no, sawv cev los ntawm Io. Thaum lub hwj chim mov voltage yog tas li:
Nws tuaj yeem txiav txim siab seb puas muaj cov resonance tshwm sim raws li seb qhov tam sim no ntawm RLC series Circuit Court tau mus txog qhov siab tshaj plaws.
c. Qhov hluav taws xob ntawm L thiab C yog sib npaug hauv qhov loj, tawm tsam hauv kev coj, thiab tshem tawm ib leeg tawm
Yog li, series resonance, tseem hu ua voltage resonance, muaj qhov sib npaug impedance ntawm 0 ntawm ob qho kawg ntawm inductor thiab capacitor thaum lub sij hawm resonance, uas yog sib npaug rau luv luv Circuit Court.
d. Qhov voltage ntawm lub resistor yog sib npaug rau lub hwj chim mov voltage thiab ncav cuag nws qhov siab tshaj plaws tus nqi.
e. Hwj chim
Lub zog muaj zog: Lub zog tsim los ntawm lub zog hluav taws xob thiab lub zog siv los ntawm kev tiv thaiv hluav taws xob, nrog lub zog siab tshaj plaws
Reactive zog: Thaum lub sij hawm resonance, lub Circuit Court tsis nqus reactive zog los ntawm sab nraud. Tab sis muaj ib lub sij hawm sib pauv ntawm magnetic teb zog thiab hluav taws xob teb zog ntawm lub inductance thiab capacitance hauv Circuit Court.
Simulation ntawm series resonant circuit
Nyob rau hauv ib tug series Circuit Court muaj li ntawm resistors, inductors, thiab capacitors, thaum lub capacitive reactance XC yog sib npaug zos rau inductive reactance XL, piv txwv li XC =XL, lub theem ntawm voltage U thiab tam sim no kuv nyob rau hauv lub Circuit Court yog tib yam, thiab lub Circuit Court muaj ib tug ntshiab resistive cwj pwm. Qhov no tshwm sim yog hu ua series resonance. Thaum ib tug series resonance tshwm sim nyob rau hauv ib tug Circuit Court, lub impedance ntawm lub Circuit Court Z=√ R ^ 2+(XC-XL) ^ 2=R, tag nrho impedance nyob rau hauv Circuit Court yog txo, thiab tam sim no yuav ncav cuag nws cov nqi siab tshaj.
1. Tsim ib tug series resonant circuit. Xaiv ib qhov voltage, resistor, capacitor, thiab inductor los ntawm lub tsev qiv ntawv tivthaiv los ua ib lub voj voog resonant. Xaiv qhov zaus tus yam ntxwv meter XBP1 thiab txuas nws cov input davhlau ya nyob twg mus rau lub hwj chim mov thiab tso zis davhlau ya nyob twg mus rau lub load.
2. Theem zaus yam ntxwv ntawm ib tug series resonant Circuit Court: Nyem rau theem khawm nyob rau hauv hom kev xaiv pab pawg kom tau cov theem zaus yam ntxwv ntawm lub Circuit Court.
3. Los ntawm cov yam ntxwv theem zaus ntawm cov kab hluav taws xob resonant, nws tuaj yeem pom tau tias qhov hluav taws xob tau muab faib los ntawm qhov resonant zaus f0. Thaum lub teeb liab zaus qis dua f0, theem coj; Thaum lub teeb liab zaus siab tshaj f0, muaj ib theem lag. Vim hais tias thaum lub teeb liab zaus qis dua f0, tag nrho Circuit Court yog capacitive, thiab cov theem tam sim no (voltage theem ntawm load resistor) ua rau theem voltage (sab nraud fais fab mov); Thaum lub teeb liab zaus siab tshaj f0, tag nrho cov Circuit Court ua inductive, thiab cov theem tam sim no (voltage theem ntawm load resistor) lags tom qab voltage (sab nraud fais fab mov). Cov txiaj ntsig simulation tau zoo ib yam nrog kev tsom xam theoretical.
4. Cov kev sib raug zoo ntawm qhov zoo tshaj plaws Q tus nqi ntawm ib tug series resonant Circuit Court thiab cov selectivity ntawm lub Circuit Court: thaum ua kom lub series resonant zaus tsis tu ncua, piv txwv li L thiab C, hloov cov khoom tsis muaj peev xwm hloov qhov zoo yam Q tus nqi ntawm lub Circuit Court. Hauv Circuit Court, R=1 k Ω, L=1 H, C=1 μF, Yog Q=[1RLC=1,], thiab capacitance C1=1 μ F, inductance L1=1 H, thiab kuj R1=100 Ω raug xaiv, tom qab ntawd Q=[1RLC=10,]. Rau RLC series resonant circuits, qhov sib txawv Q qhov tseem ceeb sib haum mus rau qhov sib txawv ntawm qhov sib txawv zaus tus yam ntxwv nkhaus. Qhov loj dua tus nqi Q, qhov ntse dua qhov sib thooj amplitude zaus tus yam ntxwv nkhaus, thiab qhov zoo dua qhov kev xaiv ntawm Circuit Court. Yog hais tias ib tug series xaiv Circuit Court yog siv raws li ib tug xov tooj cua kuaj Circuit Court, nws rhiab heev yog siab dua thiab nws anti{19}} muaj peev xwm cuam tshuam yog qis dua; Qhov tsawg dua tus nqi Q, qhov blunter qhov sib thooj amplitude zaus tus yam ntxwv nkhaus, thiab cov kev xaiv ntawm Circuit Court deteriorates. Yog tias siv raws li lub xov tooj cua ntsuas hluav taws xob, nws qhov rhiab heev txo qis, tab sis nws txoj kev tiv thaiv - muaj peev xwm cuam tshuam yuav raug txhim kho. Yog li ntawd, tus nqi Q ntawm series resonant Circuit Court yuav tsum raug xaiv raws li qhov kev thov tshwj xeeb.
