Wireless charging kawg tso tawm DC.
Cov txheej txheem ntawm kev them nyiaj wireless yog qhov nyuaj. Ua ntej, nws lub zog tawm tswv yim feem ntau yog AC, xws li 220V AC muab los ntawm tsev neeg lub qhov hluav taws xob txuas nrog lub wireless charger. Lub wireless charger muaj cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob sab hauv, uas yuav hloov cov tswv yim AC mus rau AC high-frequency AC, thiab tom qab ntawd ua kom muaj kev hloov pauv hauv magnetic teb los ntawm cov xaim xaim. Thaum lub coil ntawm qhov kawg tau txais nyob rau hauv qhov chaw sib nqus no, AC yuav raug ntxias. Txawm li cas los xij, AC no tsis tuaj yeem them cov khoom siv hluav taws xob ncaj qha. Lub voj voog nyob rau hauv qhov kawg tau txais yuav kho qhov induced AC, hloov mus rau hauv DC ruaj khov, thiab thaum kawg them lub roj teeb ntawm lub tshuab hluav taws xob.
Txawm hais tias wireless charging thev naus laus zis dhau los hloov pauv ntawm AC thiab sib nqus teb thaum lub zog xa mus, nws lub hom phiaj tseem ceeb yog muab DC ruaj khov rau cov khoom siv hluav taws xob kom ua tau raws li cov kev xav tau ntawm cov khoom siv roj teeb, ib yam li qhov kawg ntawm cov khoom siv hluav taws xob yog DC, muab kev ntseeg siab. qhov chaw ntawm lub zog rau peb cov khoom siv hluav taws xob.
