Momwe mungasankhire njira yoyenera wamba inductor | KHALANI BWINO

Kwa inductors wamba, pali mitundu yambiri ya zosefera za EMI, monga mikanda ya ferrite, mphete zamaginito, ma capacitor atatu osachiritsika, ma inductor opitilira muyeso, oyendetsa modutsa wamba ndi zina zambiri. Chilichonse chimakhala ndi gawo lofunikira pama circuits osiyanasiyana.Ilinso ndi chotchinga chabwino pamagwiridwe anthawi zonse wamba mode inductor kukuuzani momwe mungasankhire inductor wamba wamba.

Mfundo zofananira wamba

Njira zofananira zimapangidwa ndi gulu lama coil okhala ndi nambala yomweyo koma olowera mbali zosiyana. Pamene maginito othinana mu mphete yamaginito amangokhalira kulumikizana pakamayenda, imapanga kutulutsa kwakukulu, komwe kumalepheretsa magwiridwe antchito apano. Pamene maginito othinana mu mphete yamaginito akuyenda, imatha kuthamangitsana, ndipo sipangakhale kulowererapo, chifukwa imatha kudutsa popanda kuponderezedwa.

Momwe mungasankhire mawonekedwe oyenera a inductor, tifunikira kulingalira zomwe zimafotokozedwa ndi SMT yodziwika bwino.

1. Kuyika voliyumu

Ma moductors wamba amakhala ndi mapulagini ndi zigamba, ndipo kuwumba konsekonse, kutengera kusankha kwenikweni kwa ma dera, mapulagini samangokhazikitsa zigamba.

2. Kukula kwa inductance kukula

Chifukwa mafotokozedwe a wamba-inductor-inductor, mavuto monga tekinoloje yaukadaulo, yoyambitsidwa ndi njira yodziwika bwino yopangira ma inductor silingafanane chimodzimodzi, zomwe zimapangitsa kutayikira, komwe kumatchedwa "kutayikira kwa inde", samalani kuti muganizire zotsatira zakusiyana kwamayendedwe amachitidwe, makamaka mayendedwe othamanga kwambiri, koma kutayikira kwa kutulutsa kwa zinthu mosiyana ndikoyipa, nthawi zina kumayambitsidwa chifukwa chofala kwa kutulutsa kwazinthu zomwe nthawi zina kumatha kupulumutsa kumawonjezera kukwera mtengo kwa njira yosiyanitsira njira zigawo zikuluzikulu.

3. Impedance makhalidwe

Kulingalira kwakukulu kwa impedance posankha ambiri kuyenera kuyang'anira gulu losefera pafupipafupi, kuti muwone momwe mafotokozedwe amomwe amagwirira ntchito, makamaka kuti muwone momwe impedance pafupipafupi imakhalira, zimakhala bwino kwambiri. Mwachitsanzo, chithunzichi pansipa ndi njira yofananira yamagetsi yosinthira magetsi, yokhala ndi ma impedance osiyanasiyana pama frequency osiyanasiyana.

4. wina

Mwachitsanzo, mtengo, chizindikiritso ndi zina zotero zidzakhalanso zofunikira posankha njira zofananira.

Tikukhulupirira kuti mukawerenga, kusankha komwe kumachitika nthawi zambiri - kumamveka bwino.
