Ibhodi elisha lokuthuthukisa ishaja elingenantambo lika-St's liqondise ezimbonini, zezokwelapha kanye nezinhlelo zokusebenza zasekhaya ezihlakaniphile

I-St yethule iphakheji yokushaja okungenantambo ye-Qi ene-transmitter ne-receiver engu-50W ukuze kusheshiswe umjikelezo wokuthuthukiswa kwamashaja angenawaya wezinhlelo zokusebenza zamandla aphezulu njengamathuluzi ezokwelapha, okokusebenza kwemboni, izinto zikagesi zasendlini nama-peripherals ekhompyutha.

Ngokwamukela isixazululo esisha sokushaja okungenantambo se-ST, abathuthukisi bangaletha ukunethezeka nesivinini sokushaja sokushaja okungenantambo ezinhlelweni zokusebenza lapho amandla okukhiphayo nesivinini sokushaja kufuna kakhulu.Lokhu kuhlanganisa izinto zokuhlanza ezingenazintambo, amathuluzi kagesi angenazintambo, amarobhothi angomahambanendlwana afana ne-drones, imishini yokulethwa kwezidakamizwa zezokwelapha, amasistimu aphathwayo e-ultrasound, amalambu esiteji nokukhanya kweselula, amaphrinta nezikena.Ngenxa yokuthi izintambo, izixhumi, nokulungiselelwa kwe-docking okuyinkimbinkimbi akusadingeki, le mikhiqizo kulula ukuyiklama, ishibhile, futhi isebenza ngokwethembeka.

Isidlulisi samandla se-STEVAL-WBC2TX50 sisebenzisa iphrothokholi ye-ST Supercharge (STSC) futhi sinamandla okukhipha aphezulu afika ku-50W.I-STSC iyiphrothokholi yokushaja okungenantambo eyingqayizivele ye-ST eshaja ngokushesha kunephrothokholi evamile yokushaja okungenantambo esetshenziswa kuma-smartphone namadivayisi afanayo, okuvumela amabhethri amakhulu ukuthi ashajwe ngenani elisheshayo.Ibhodi futhi lisekela i-Qi 1.3 5W Baseline Power Profile (BPP) kanye ne-15W Extended Power Profile (EPP) izindlela zokushaja.Iphakheji yesistimu yokudlulisa Amandla kaSt's STWBC2-HP iyi-chip enkulu esebhodini futhi ihlanganisa isilawuli esincane se-STM32G071 Arm® Cortex-M0 nesiphetho sangaphambili esizinikele se-RF.Indawo engaphambili ihlinzeka ngesimo sesignali nokulawula imvamisa, ishayela ijeneretha yesiginali ye-PWM enesinqumo esiphezulu kusidluliseli, isebenzisa ugesi we-4.1V kuya ku-24V DC, futhi ihlanganisa umshayeli wesango le-MOSFET nesixhumi esibonakalayo se-USB sokushaja i-D+/D-.Ngaphezu kwalokho, iphakheji yesistimu ye-STWBC2-HP i-SiP ingabhangqwa neyunithi yezokuphepha ye-ST's STSAFE-A110 ukuze inikeze ukuqinisekiswa kwedivayisi ehambisana ne-QI.

Ibhodi elamukela amandla le-STEVAL-WLC98RX lingakwazi ukuphatha amandla okushaja afika ku-50W, lisekela ngokuphephile nangokuthembekile ukusebenza okugcwele kwezindlela zokushaja ze-STSC ne-BPP ne-EPP.I-Adaptive rectifier configuration (ARC) inweba ibanga lokushaja kufika ku-50%, ivule amathuba okusebenzisa amakhoyili anezindleko eziphansi kanye nezilungiselelo ezivumelana nezimo.Ibhodi lomamukeli futhi lihlinzeka ngesilinganiso esinembile se-voltage-yamanje sokutholwa kwento yangaphandle (i-FOD), ukuphathwa kokushisa nokuvikelwa kwesistimu.I-St's STWLC98 chip yesamukeli sokushaja okungenantambo iyi-chip enkulu esebhodini, ehlanganisa umongo we-Cortex-M3 kanye nesiteji samandla esihlanganisayo esihlanganisayo esididiyelwe kakhulu, esinamandla kagesi alungisekayo afika ku-20V.
