St's new wireless charger board imayang'ana ntchito zamafakitale, zachipatala ndi zanzeru zakunyumba

St yakhazikitsa phukusi lopangira ma waya opanda zingwe la Qi lokhala ndi ma transmitter a 50W ndi cholandilira kuti afulumizitse kadulidwe ka ma charger opanda zingwe amagetsi apamwamba kwambiri monga zida zamankhwala, zida zamakampani, zida zapakhomo ndi zolumikizira makompyuta.

Potengera njira yatsopano yopangira ma waya opanda zingwe ya ST, opanga atha kubweretsa kusavuta komanso kuthamanga kwa kulipiritsa opanda zingwe kumapulogalamu omwe mphamvu zotulutsa ndi kuthamanga kwacharcha zimafunikira kwambiri.Izi zikuphatikizapo zotsukira opanda zingwe, zida zamagetsi zopanda zingwe, maloboti am'manja monga ma drones, zida zoperekera mankhwala azachipatala, makina onyamula ma ultrasound, magetsi oyendera pasiteji ndi kuyatsa kwa mafoni, makina osindikizira ndi masikani.Chifukwa zingwe, zolumikizira, ndi masinthidwe ovuta a docking sakufunikanso, zinthuzi ndizosavuta kuzipanga, zotsika mtengo, komanso zimagwira ntchito modalirika.

The STEVAL-WBC2TX50 power transmitter imagwiritsa ntchito protocol ya ST Supercharge (STSC) ndipo imakhala ndi mphamvu yotulutsa mpaka 50W.STSC ndi njira yapadera yopangira ma waya opanda zingwe ya ST yomwe imalipira mwachangu kuposa njira yojambulira opanda zingwe yomwe imagwiritsidwa ntchito m'mafoni a m'manja ndi zida zofananira, kulola kuti mabatire akulu azilipiritsidwa mwachangu.Bungweli limathandiziranso njira zolipirira za Qi 1.3 5W Baseline Power Profile (BPP) ndi 15W Extended Power Profile (EPP).St's STWBC2-HP Power transmission system phukusi ndiye chip chachikulu pa bolodi ndikuphatikiza makina owongolera a STM32G071 Arm® Cortex-M0 okhala ndi malekezero akutsogolo a RF.Mapeto akutsogolo amapereka mawonekedwe azizindikiro ndi kuwongolera pafupipafupi, amayendetsa jenereta yowoneka bwino ya PWM pa transmitter, imagwiritsa ntchito magetsi a 4.1V mpaka 24V DC, ndipo imaphatikizanso dalaivala wachipata cha MOSFET ndi mawonekedwe a D+/D- USB.Kuphatikiza apo, STWBC2-HP system phukusi SiP itha kuphatikizidwa ndi ST's STSAFE-A110 chitetezo unit kuti ipereke chitsimikiziro cha chipangizo chogwirizana ndi QI.

Bolodi yolandirira mphamvu ya STEVAL-WLC98RX imatha kunyamula mphamvu zolipiritsa mpaka 50W, motetezeka komanso modalirika pothandizira magwiridwe antchito a STSC ndi BPP ndi ma EPP.Kusintha kwa Adaptive rectifier (ARC) kumakulitsa mtunda wochapira mpaka 50%, ndikutsegula mwayi wogwiritsa ntchito makhola otsika mtengo komanso masinthidwe osinthika.Gulu lolandila limaperekanso muyeso wolondola wamagetsi-panopa pakuzindikira zinthu zakunja (FOD), kasamalidwe kamafuta ndi chitetezo chadongosolo.St's STWLC98 chip cholandirira opanda zingwe ndiye chip chachikulu pa bolodi, chopangidwa ndi Cortex-M3 core komanso gawo lamagetsi lophatikizika bwino, lothandizira lothandizira lothandizira lokhala ndi voteji yosinthika mpaka 20V.
