Dab tsi yog qhov adjustable inductor

Feem ntau siv adjustable inductors muaj xws li oscillation coils rau semiconductor xov tooj cua, kab oscillation coils rau TVs
Linear coil, intermediate zaus notch coil, zaus them nyiaj coil rau suab, impedance kauj, thiab lwm yam.
1. Oscillating coil rau xov tooj cua semiconductor: Qhov no oscillating kauj, ua ke nrog cov capacitors sib txawv, tsim ib lub zos oscillation circuit nyob rau hauv semiconductor xov tooj cua, siv los tsim ib lub zos oscillator teeb liab nrog ib tug input tuning circuit uas tau txais ib tug xov tooj cua teeb liab siab tshaj 465kHz. Sab nrauv yog cov hlau thaiv npog, thiab sab hauv yog tsim los ntawm nylon hauv ob sab phlu, I-shaped sib nqus core, magnetic cap, thiab pin puag. Ntawm I-shaped magnetic core, muaj lub zog muaj zog enameled hlau winding. Lub kaus mom hlau nplaum yog ntsia rau ntawm ib lub nylon thav duab nyob rau hauv lub shielding cover thiab muaj peev xwm tig mus thiab down kom hloov lub inductance ntawm lub kauj los ntawm kev hloov nws nyob deb ntawm lub kauj. Cov qauv sab hauv ntawm cov zaus notch coil hauv lub TV zoo ib yam li oscillation coil, tshwj tsis yog tias lub kaus mom hlau nplaum tuaj yeem kho cov tub ntxhais sib nqus.
2. Kab oscillation coil rau TV: Kab oscillation coil tau siv rau hauv TV dub thiab dawb thaum ntxov. Nws tsim ib tug kheej-excited oscillation Circuit Court (peb-point oscillator los yog intermittent oscillator, multi harmonic oscillator) nrog peripheral tsis kam thiab capacitance Cheebtsam thiab kab oscillation transistors, siv los tsim ib tug duab pulse voltage teeb liab nrog ib zaus ntawm 15625HZ.
Qhov nruab nrab ntawm cov tub ntxhais sib nqus ntawm lub kauj muaj ib lub qhov square, thiab kab synchronization hloov kho pob qhov rooj ncaj qha mus rau hauv lub qhov square. Los ntawm rotating kab synchronization hloov kho pob qhov rooj, qhov kev ncua deb ntawm cov tub ntxhais sib nqus thiab cov kauj tuaj yeem hloov pauv, yog li hloov cov inductance ntawm lub kauj thiab ua kom cov kab oscillation zaus ntawm 15625HZ, uas ua rau synchronous oscillation nrog kab synchronization pulse xa los ntawm cov Tsis siv neeg zaus tswj Circuit Court (AFC).
3. Kab linear coil: Ib kab linear coil yog nonlinear magnetic saturation inductance coil (nws inductance txo qis nrog qhov nce ntawm tam sim no), uas feem ntau txuas nrog hauv kab hauv kab deflection coil Circuit Court thiab siv nws cov yam ntxwv sib nqus saturation los them rau linear. distortion ntawm daim duab.
Ib txoj kab hluav taws xob yog tsim los ntawm winding enameled hlau ntawm I-shaped ferrite high-frequency core los yog ferrite magnetic pas nrig, nrog adjustable mus tas li hlau nplaum ntsia ntawm lub kauj. Los ntawm kev hloov qhov txheeb ze ntawm cov hlau nplaum tas mus li thiab cov kauj, qhov loj ntawm coil inductance hloov pauv kom ua tiav cov nyiaj them poob haujlwm.
