Nrog rau qhov tshwm sim ntawm 5G smartphones, lub charger kuj tau hloov mus rau hauv tus qauv tshiab.Muaj ib yam tshiab ntawm lub charger, uas tsis tas yuav muaj lub charger cable los them lub xov tooj ntawm tes.Lub xov tooj ntawm tes tuaj yeem them nyiaj tsuas yog muab tso rau ntawm lub phaj ncig, thiab qhov kev them nqi nrawm dua.Qhov no yog lub wireless charger, yog li no wireless charger tiag tiag siv tau yooj yim?
Wireless charging yog siv rau hauv kev them nyiaj ntawm cov khoom siv hluav taws xob xws li xov tooj ntawm tes.Lub hauv paus ntawm nws cov kev them nyiaj yog wireless zog kis tau tus mob technology.Muaj ob hom kev them nyiaj wireless: electromagnetic induction charging thiab resonant charging.
Electromagnetic induction charging feem ntau yog siv nyob rau hauv cov khoom siv hluav taws xob tsawg, xws li cov xov tooj ntawm tes thaum lub sij hawm resonant charging yog siv nyob rau hauv high-power electronics.Piv txwv li, feem ntau cov tsheb fais fab siv resonant charging.
Txij li thaum lub zog kis tau tus mob ntawm lub charger thiab cov khoom siv hluav taws xob los ntawm qhov chaw sib nqus, thiab tsis muaj cov xov hlau txuas rau kev xa hluav taws xob ntawm ob, lub charger thiab cov khoom siv hluav taws xob tsis tas yuav txuas nrog cov xov hlau.Ib qho khoom siv hauv lub wireless charger yog qhov tseem ceeb kom paub txog kev them nyiaj wireless: NP0 capacitor.
NP0 capacitor yog ib homceramic capacitor, uas belongs rau chav kawm I ceramic capacitor.Nws muaj cov yam ntxwv ntawm qhov kub thiab txias, tsis muaj dielectric poob thiab kub stability.Nws qhov chaw ua haujlwm kub yog -55 ℃ ~ + 125 ℃.Nyob rau hauv ib puag ncig no, qhov kev hloov pauv ntawm lub peev xwm ntawm NPO capacitor yog me me, yog li nws yog hu ua kub them nyiaj capacitor.Nws yog tsim rau oscillators, resonant circuits, high zaus circuits, thiab lwm yam circuits uas yuav tsum tau tsawg poob thiab ruaj khov capacitance, los yog rau kub them.
Lub NP0 capacitor txuas nrog hauv series nrog lub transmitter kauj hauv lub wireless charger kom phim lub transmitter kauj los tsim ib qho kev hloov hluav taws xob uas tuaj yeem txais los ntawm tus txais.
Lub NP0 capacitor yog qhov me me thiab tsis siv qhov chaw, thiab tsim nyog siv rau hauv cov khoom uas xav tau ntim siab xws li wireless charging.Cov yam ntxwv ntawm qhov tsis tshua muaj dielectric poob, qhov kub thiab txias stability, kev ua haujlwm zoo tuaj yeem txhim kho wireless charging efficiency, txo lub zog poob thiab wireless charging thiab cua sov.
Nrog lub wireless charging, nws yooj yim dua rau them lub xov tooj smartphone.Koj tsis tas yuav siv sijhawm los nrhiav lub charger cable los ntsaws rau hauv lub xov tooj ntawm tes.Koj tuaj yeem them lub xov tooj ntawm tes ncaj qha ntawm lub wireless charger.
Xaiv cov chaw tsim khoom txhim khu kev qha thaum yuav cov khoom siv ceramic tuaj yeem zam ntau yam teeb meem tsis tsim nyog.JYH HSU (los yog Dongguan Zhixu Electronics) tsis tsuas yog muaj tag nrho cov qauv ntawm ceramic capacitors nrog lav zoo, tab sis kuj muaj kev txhawj xeeb tom qab muag.Yog tias koj tab tom nrhiav rau cov khoom siv hluav taws xob, txais tos hu rau peb.
