Tus txheej txheem tsim ntawm receiver coil ntawm wireless charger
Thaum peb tsis nkag siab txog kev them nyiaj wireless, peb yuav xav tias nws yuav tsum yog ib txoj haujlwm nyuaj heev. Qhov tseeb, qhov no tsis yog qhov xwm txheej. Peb tsuas yog yuav tsum tau ua lub wireless charging transmitting coil thiab lub wireless charging tau txais kauj los tsim qhov yooj yim wireless charging puag ncig. Tam sim no peb tuaj yeem sim nws. Cov kauj ruam tsim qauv ntawm lub receiver coil ntawm lub wireless charger yog raws li hauv qab no.
(1) paub meej tias qhov xav tau rau Wireless charger txais tos.
(2) nkag siab txog cov kev txwv ntawm lub cev tsim: xy thiab Z loj txwv ntawm lub kauj; kwv yees lub interface clearance.
(3) xaiv cov kev txwv hauv qab no: lub zog xav tau los ntawm kev thauj khoom; qhov xav tau kev sib txuas coefficient ntawm TX thiab Rx coils; qhov chaw tso cai ntawm Rx coils.
(4) siv lub voj voog los khiav lub simulation raws li qhov zoo tshaj plaws ntawm kev txais qhov chaw.
(5) tso saib lub load kab nkhaus thiab txiav txim seb qhov nkhaus puas tau.
(6) tsim kom tau txais coil yam ntxwv tshwj xeeb uas tuaj yeem xa mus rau cov khoom siv sib nqus; tsim RX neeg siv BOM.
(7) tsim thiab sim tus qauv ntawm tus neeg sim uas tau xaiv los ntawm Ti.
(8) kawg ntawm coil tsim.
Cov ntaub thaiv npog
Lub wireless charger hloov los ntawm 220V fais fab mov mus rau lub sympathetic electromagnetic teb, thiab ces lub sympathetic electromagnetic teb generates ib tug sympathetic electromagnetic teb, thiab ces lub sympathetic electromagnetic teb hloov mus rau tam sim no them; Thaum lub sympathetic electromagnetic teb ntsib hlau, nws yuav tsim hluav taws xob eddy tam sim no, uas yuav ua rau cov tawv nqaij nyhuv ntawm cov hlau, tsim hluav taws xob lub zog ntawm cov hlau, txo cov nqi them efficiency thiab pov tseg hluav taws xob hluav taws xob. Thiab qhov cuam tshuam rau lub rooj tsav xwm tseem ceeb ntawm txoj kab cuam tshuam rau kev ua haujlwm ib txwm ntawm tag nrho lub charger. Nrog rau daim ntawv ferrite (thickness 0.4-0.6mm), qhov permeability tuaj yeem ncav cuag 800. Los ntawm cov hlau nplaum sib nqus, nws tuaj yeem muab ib lub voj voog rau kev sib nqus sib nqus, uas tuaj yeem txhim kho qhov ua tau zoo.
Cov ntaub thaiv npog muaj ob lub luag haujlwm tseem ceeb:
(1) muab txoj hauv kev qis impedance rau cov hlau nplaum sib nqus, kom muaj cov kab hluav taws xob tsawg heev uas tuaj yeem cuam tshuam cov khoom siv hlau nyob ib puag ncig.
(2) siv tsawg lem kom paub qhov siab dua inductance coil kom txo cov coil tsis kam (qhov ntau tig, qhov siab dua).
Cov ntaub thaiv npog tuab uas nqus tau cov khoom sib nqus ntau (lawv muaj cov ntsiab lus siab saturation) tuaj yeem siv los tiv thaiv cov khoom tom qab RX coil los ntawm cua sov. Thaum TX lossis RX nrog calibration hlau nplaum raug ntsib, qhov ua tau zoo ntawm cov khoom siv tiv thaiv tuab yog cuam tshuam tsawg dua li cov khoom siv tiv thaiv nyias.
Cov neeg tsim khoom xws li Vishay, TDK, Panasonic, E & E, elytone thiab mingstar tuaj yeem muab cov ntaub thaiv npog zoo ib yam, uas tuaj yeem pab txo qis kev ua haujlwm tsis zoo.
Thov nco ntsoov tias cov khoom siv ferrite siab (xws li hmoov hlau, thiab lwm yam) tsis yog ib txwm zoo dua li cov ntaub ntawv gapped. Txawm hais tias cov ntaub ntawv ferrite muaj cov hlau nplaum sib nqus, qhov saturation point ntawm flux yog tsawg thaum lub thickness ntawm shielding khoom txo. Qhov no yuav tsum tau ua tib zoo xav txog.
