St's tshiab wireless charger txhim kho pawg thawj coj saib xyuas kev lag luam, kev kho mob thiab kev siv hauv tsev ntse

St tau tshaj tawm Qi wireless charging pob nrog 50W transmitter thiab receiver kom nrawm lub voj voog kev loj hlob ntawm wireless chargers rau kev siv hluav taws xob siab xws li cov cuab yeej siv kho mob, cov cuab yeej siv hauv tsev, cov khoom siv hauv tsev thiab cov khoom siv computer.

Los ntawm kev siv ST cov kev daws teeb meem tshiab wireless charging, cov neeg tsim khoom tuaj yeem nqa qhov yooj yim thiab them ceev ntawm wireless charging rau cov ntawv thov uas tso zis hluav taws xob thiab kev them nqi nrawm dua.Cov no suav nrog cov tshuab nqus tsev tsis muaj zog, cov cuab yeej siv hluav taws xob tsis muaj zog, cov neeg hlau txawb xws li drones, cov cuab yeej siv tshuaj kho mob, cov khoom siv ultrasound portable, theem teeb thiab lub teeb txawb, tshuab luam ntawv thiab scanners.Vim hais tias cov cables, connectors, thiab complex docking configuration tsis tas yuav tsum tau lawm, cov khoom no yog yooj yim rau tsim, pheej yig dua, thiab ua hauj lwm ntau ntseeg tau.

STEVAL-WBC2TX50 lub zog xa hluav taws xob siv ST Supercharge (STSC) raws tu qauv thiab muaj lub zog tso zis ntau txog 50W.STSC yog ST qhov tshwj xeeb wireless charging raws tu qauv uas them sai dua tus qauv wireless charging raws tu qauv siv hauv smartphones thiab cov khoom siv zoo sib xws, tso cai rau cov roj teeb loj dua kom them tus nqi sai dua.Lub Rooj Tswjhwm Saib kuj txhawb Qi 1.3 5W Baseline Power Profile (BPP) thiab 15W Extended Power Profile (EPP) them hom.St's STWBC2-HP Fais fab kis tau tus mob pob yog lub ntsiab ntawm lub nkoj nti thiab integrates STM32G071 Arm® Cortex-M0 microcontroller nrog RF nplooj siab rau pem hauv ntej kawg.Lub pem hauv ntej kawg muab cov teeb liab txias thiab zaus tswj, tsav lub siab-resolution PWM teeb liab lub tshuab hluav taws xob ntawm lub transmitter, siv 4.1V rau 24V DC fais fab mov, thiab suav nrog MOSFET rooj vag tsav tsheb thiab USB them D + / D- interface.Tsis tas li ntawd, STWBC2-HP system pob SiP tuaj yeem ua ke nrog ST's STSAFE-A110 chav ruaj ntseg los muab QI-tshaj ntaus ntawv pov thawj.

STEVAL-WLC98RX lub hwj chim txais lub rooj tsavxwm tuaj yeem tuav lub zog them txog li 50W, muaj kev nyab xeeb thiab ntseeg tau txhawb nqa kev ua haujlwm tag nrho ntawm STSC thiab BPP thiab EPP them hom.Adaptive rectifier configuration (ARC) txuas ntxiv qhov kev them nqi mus txog 50%, qhib qhov muaj peev xwm ntawm kev siv cov coils qis dua thiab hloov tau yooj yim dua.Lub receiver board kuj muab qhov tseeb voltage-tam sim no ntsuas rau txawv teb chaws khoom nrhiav pom (FOD), thermal tswj thiab kev tiv thaiv system.St's STWLC98 wireless charging receiver nti yog lub hauv paus tseem ceeb ntawm lub nkoj nti, suav nrog Cortex-M3 core thiab kev sib koom ua ke, ua haujlwm zoo synchronous rectifier fais fab theem nrog adjustable tso zis voltage mus txog 20V.
