Taw qhia rau Inductance

Inductance yog cov cuab yeej tseem ceeb ntawm cov hluav taws xob hluav taws xob uas txhawj xeeb txog lub peev xwm ntawm cov xaim los khaws lub zog hauv qhov chaw sib nqus thaum muaj hluav taws xob dhau los ntawm cov hlau. Cov inductors me me, xws li cov nyob hauv ntau txhiab lub tshuab hluav taws xob, siv txoj cai no los tswj tam sim no thiab lim cov cim. Qhov kev siv ntawm inductor's magnetic teb nyob ntawm qhov tam sim no ntws los ntawm lwm yam khoom siv lub cev xws li tus naj npawb ntawm kev tig thiab qhov xwm txheej ntawm cov khoom tseem ceeb. Qhov kev paub tseem ceeb no muaj txiaj ntsig zoo los nthuav tawm muaj nyob rau hauv cov inductors me me thiab cov kev siv sib txawv hauv cov khoom siv hluav taws xob niaj hnub no.

Hom Me Inductors

Muaj ob yam ntxwv ntawm qhov me me inductors tuaj yeem raug cais tawm. Cov khoom siv tseem ceeb thiab kev teeb tsa, txhua hom tsim nyog rau cov ntawv thov tshwj xeeb uas suav nrog cov khoom siv hluav taws xob smoothing thiab teeb liab ua. Cov cua-core, ferrite-core, thiab toroidal inductors feem ntau yog siv. Air-core inductors tsis muaj cov tub ntxhais sib nqus hlau uas ua rau muaj qhov inductance tsawg dua thiab poob thaum nyob hauv cov tub ntxhais lub zog uas ua rau lawv tsim nyog rau cov zaus siab. Lub caij no, ferrite-core inductors muaj cov yam ntxwv sib nqus tso cai rau ntau dua inductance thiab tuaj yeem siv rau lub hom phiaj ntawm kev tawm suab nrov thiab hloov hluav taws xob.
