Lub wireless charging coil yog dab tsi?

Awireless charging coilyog ib qho tseem ceeb hauv kev them nyiaj wireless technology. 1. **Txoj cai ntawm Kev Ua Haujlwm** - Nws ua haujlwm raws li lub hauv paus ntsiab lus ntawm electromagnetic induction. Nyob rau hauv lub wireless charging system, muaj ib qho xaim xaim hauv lub hauv paus them thiab ib qho tau txais kauj hauv lub cuab yeej yuav tsum tau them. Thaum ib qho alternating tam sim no (AC) dhau los ntawm cov xaim hluav taws xob, nws tsim ib qho chaw sib nqus sib nqus. Cov coil txais, muab tso rau hauv qhov chaw sib nqus no, muaj kev hloov pauv hauv cov hlau nplaum sib nqus. Raws li Faraday txoj cai ntawm electromagnetic induction, electromotive force (EMF) yog induced nyob rau hauv lub txais kauj. Yog hais tias qhov tau txais coil tsim ib lub voj voog kaw, qhov hluav taws xob cuam tshuam yuav ntws, uas yog siv los them cov khoom siv. Piv txwv li, nyob rau hauv tus qauv Qi wireless charging tus qauv, kev xa tawm thiab txais cov coils tau ua tib zoo tsim los rau ob peb sib nqus sib nqus rau kev hloov pauv zog. Qhov zaus ntawm cov magnetic teb generated los ntawm transmitting kauj yog feem ntau nyob ib ncig ntawm 100 - 200 kHz. 2. **Structure and Materials** - **Structure**: - Wireless charging coils feem ntau muaj ib lub hom phiaj - kauv qauv. Qhov kev tsim no tso cai rau ntau qhov kev sib hloov ntawm cov xaim nyob rau hauv qhov chaw txwv, uas tuaj yeem ua rau kom muaj zog electromotive. Tus naj npawb ntawm cov lem, sab hauv txoj kab uas hla, thiab sab nraud txoj kab uas hla ntawm lub coil cuam tshuam rau nws tus nqi inductance. Tus nqi inductance, nyob rau hauv lem, yog ib qho tseem ceeb uas txiav txim siab them efficiency thiab lub zog. Piv txwv li, ntau lem feem ntau ua rau tus nqi inductance ntau dua, tab sis nws kuj tuaj yeem ua rau muaj kev tiv thaiv ntawm lub kauj thiab ua rau lub zog poob ntau dua. - ** Khoom siv **: - Cov hlau siv feem ntau yog enamel - coated hlau. Lub enamel txheej ntawm tooj liab xaim muab rwb thaiv tsev, tiv thaiv luv luv-circuits ntawm ib sab lem thaum coil winding. Tooj liab yog ib qho khoom siv zoo heev uas muaj qhov tsis muaj zog, uas yuav pab txo qis qhov tsis kam ntawm lub kauj. Tsis tas li ntawd, txhawm rau txhim kho lub zog thiab kev ruaj ntseg ntawm lub kauj, qee qhov wireless charging coils yog qhwv nrog cov khoom sib nqus xws li ferrite. Cov khoom siv hlau nplaum tuaj yeem ua rau lub zog sib nqus, txhim kho kev them nqi, thiab txo qhov cuam tshuam ntawm cov hlau nplaum rau lwm yam khoom siv hluav taws xob.
