FCC ikupereka zofunikira zatsopano za WPT

Chiphaso cha FCC

Pa Okutobala 24, 2023, US FCC idatulutsa KDB 680106 D01 ya Wireless Power Transfer. FCC yaphatikiza malangizo omwe aperekedwa ndi msonkhano wa TCB m'zaka ziwiri zapitazi, monga momwe zafotokozedwera pansipa.

Zosintha zazikulu pakulipiritsa opanda zingwe KDB 680106 D01 ndi motere:

1.Malangizo a satifiketi ya FCC pakuyitanitsa opanda zingwe ndi FCC Gawo 15C § 15.209, ndipo kangati kagwiritsidwe ntchito ka chinthucho kuyenera kutsata magawo a Gawo 15C § 15.205 (a), ndiko kuti, zida zovomerezedwa ndi Gawo 15 siziyenera kugwira ntchito 90-110 kHz frequency band. Kuphatikiza pakukwaniritsa zofunikira pakuwongolera, malondawo akuyeneranso kutsatira zomwe KDB680106.

2.Malinga ndi mtundu watsopano wa KDB (KDB680106 D01 Wireless Power Transfer v04) pazida zolipiritsa opanda zingwe zomwe zidalengezedwa pa Okutobala 24, 2023, ngati zinthu zotsatirazi sizikwaniritsidwa, ECR iyenera kuyendetsedwa! Wopemphayo amafunsira kwa mkulu wa FCC molingana ndi malangizo a KDB kuti alandire chilolezo cha FCC, chomwe ndi kafukufuku wa labotale yoyeserera.

Koma chinthucho chikhoza kumasulidwa chikakumana ndi izi:

(1) Mphamvu kufala pafupipafupi m'munsimu 1 MHz;

(2) Mphamvu yotulutsa ya chinthu chilichonse chotumizira (monga koyilo) ndi yochepera kapena yofanana ndi 15W;

(3) Perekani katundu wovomerezeka wokwanira kuyesa kukhudzana kwa thupi pakati pa periphery ndi transmitter (ie kukhudzana kwachindunji pakati pa pamwamba pa transmitter ndi zotumphukira zida casing chofunika);

(4) Only § 2.1091- Mikhalidwe yokhudzana ndi mafoni imagwira ntchito (ie lamulo ili silikuphatikiza §

Kuyesa kwa FCC

2.1093- Mikhalidwe yowoneka bwino);

(5) Zotsatira za mayeso a RF ziyenera kutsatira zoletsa;

(6) Chipangizo chokhala ndi zida zopitilira imodzi, mwachitsanzo: chipangizochi chingagwiritse ntchito makola atatu okhala ndi mphamvu ya 5W kapena koyilo imodzi yokhala ndi mphamvu ya 15W. Pamenepa, mayiko onsewa akuyenera kuyesedwa, ndipo zotsatira zake ziyenera kukwaniritsa zomwe zili (5).

Ngati chimodzi mwazomwe zili pamwambazi sichikukwaniritsa zofunikira, ECR iyenera kuchitidwa. Mwanjira ina, ngati chojambulira chopanda zingwe ndi chida chonyamulika, ECR iyenera kuchitidwa ndipo izi ziyenera kuperekedwa:

-Kugwira ntchito pafupipafupi kwa WPT

- Mphamvu ya koyilo iliyonse mu WPT

-Ziwonetsero zowonetsera zida zam'manja kapena zam'manja, kuphatikiza zidziwitso zotsatiridwa ndi RF

-Kutalikirana kwambiri ndi ma transmitter a WPT

3. Chipangizo chojambulira opanda zingwe WPT chatanthauzira zofunikira za chipangizo patali ≤ 1m ndi> 1m.

A. Ngati mtunda wotumizira wa WPT uli ≤ 1m ndipo ukukwaniritsa zofunikira za KDB, palibe chifukwa chotumizira zokambirana za KDB.

B. Ngati mtunda wotumizira wa WPT uli ≤ 1m ndipo sukukwaniritsa zofunikira za KDB, kukambirana ndi KDB kuyenera kutumizidwa ku FCC kuti ivomereze.

C. Ngati mtunda wotumizira wa WPT ukuposa 1m, kufunsira kwa KDB kuyenera kuperekedwa ku FCC kuti ivomerezedwe.

4. Zida zochapira opanda zingwe WPT zikavomerezedwa molingana ndi malamulo a FCC Part 18 kapena Part 15C, kaya ndi FCC SDoC kapena FCC ID Certification, kukambirana kwa KDB kuyenera kutumizidwa ku FCC kuti ivomerezedwe asanavomerezedwe ngati chilolezo chovomerezeka.

5. Pakuyesa kuwonetseredwa kwa RF, mphamvu ya kumunda siing'ono mokwanira (pakati pa probe sensing element ndi yoposa 5 mm kuchokera kunja kwa probe). Ndikofunikira kuwerengera zotsatira pa 0mm malinga ndi zofunikira za gawo 3.3, ndi magawo a 2cm ndi 4cm, kuwerengera ngati zotsatira za mayeso zili mkati mwa 30% kupatuka. Perekani njira zowerengetsera ma fomula ndi njira zowunikira zamitundu yofufuza mphamvu zam'munda zomwe sizikukwaniritsa zofunikira zoyesa mtunda. Ndipo zotsatirazi ziyenera kudutsa PAG panthawi ya certification ya TCB.

Chithunzi 1: Chitsanzo cha kuyeza kwa probe (chikasu) pafupi ndi zida za WPT (zofiira/zofiirira).
Radiyo ya probe ndi mamilimita 4, kotero malo oyandikira kwambiri ku chipangizo chomwe chingayeze gawolo ndi mamilimita 4 kuchokera pa mita (chitsanzo ichi chikuganiza kuti probe calibration imatanthawuza pakati pa gawo lozindikira, pomwepa ndi gawo. ). Kutalika kwake ndi 4 millimeters.
Zomwe zili pa 0 mm ndi 2 mm ziyenera kuyesedwa kupyolera mu chitsanzo, ndiyeno chitsanzo chomwecho chiyenera kutsimikiziridwa pochiyerekeza ndi miyeso yeniyeni pa 4 mm ndi 6 mm, kuti apeze kafukufuku ndikusonkhanitsa deta yolondola.
6.Kwa ma transmitters a WPT oyendetsedwa ndi katundu wokhala ndi mtunda wosapitilira ⼀⽶, popanga WPT yokhala ndi ma radiation angapo, mtunda wa katunduyo uyenera kuganiziridwa monga momwe tawonetsera pa Chithunzi 3, ndipo miyeso iyenera kutengedwa pakati pa wolandila ndi kufalitsa kwapafupi. kapangidwe.

Chithunzi 2

a) Kwa makina ambiri olandirira (pomwe pali olandila awiri, monga momwe tawonetsera pa matebulo a RX1 ndi RX2), malire a mtunda ayenera kugwiritsidwa ntchito kwa onse olandila omwe akukhudzidwa pakulipiritsa.

b) Chipangizo chojambulira opanda zingwe cha WPT chimatengedwa ngati "kutalika" chifukwa chimatha kugwira ntchito pomwe RX2 ili kutali ndi mita yopitilira awiri kuchokera pa chotumizira.

Chithunzi 3

Kwa makina otumizira ma coil ambiri, malire amtunda amayezedwa kuchokera kumphepete mwapafupi kwa koyiloyo. Kukonzekera kwa katundu kwa ntchito ya WPT mkati mwamtundu wina kumalembedwa ndi font yobiriwira. Ngati katunduyo angapereke mphamvu zoposa mita imodzi (zofiira), ziyenera kuonedwa ngati "mtunda wautali".

BTF Testing Lab, kampani yathu ili ndi ma electromagnetic compatibility laboratories, ma labotale achitetezo, Laboratory yopanda zingwe, Laboratory ya batri, Laboratory ya Chemical, SAR Laboratory, HAC Laboratory, ndi zina zambiri. Tapeza ziyeneretso ndi zilolezo monga CMA, CNAS, CPSC, A2LA, VCCI, ndi zina zotero. Kampani yathu ili ndi gulu lodziwa bwino ntchito zaukadaulo, lomwe lingathandize mabizinesi kuthetsa vutoli. Ngati muli ndi zofunikira zoyezetsa komanso zotsimikizira, mutha kulumikizana mwachindunji ndi ogwira ntchito athu Oyesa kuti mupeze zambiri zamtengo wapatali komanso zambiri zozungulira!
