Wireless charger hman dan tur .

Brand hrang hrangte thil siamte charger inang an insem theihna tur leh wireless charger-te versatility tihchangtlunna tur, khawvela wireless charging technology tihhmasawn tura standardization organization hmasa ber, wireless power consortium (heta tang hian "Aliance" tia sawi a ni tawh ang), chuan "wireless charging" standard a siam chhuak ta a ni. Wireless Power Consortium (WPC) standard hnuaiah chuan wireless transmission-a power hman zat chu 0~5W chauh a ni. He standard range zawmtu system te hian planar coil pahnih inkara inductive coupling hmangin power transmitter atanga power receiver-a power an transfer theih nan an hmang thin. Primary leh secondary coil inkar hlat zawng hi a tlangpuiin 5mm a ni a, output voltage regulation chu global digital control loop hmanga enkawl a ni. Hetih lai hian power receiver hian power transmitter nen an inbiak a, power consumption a siam chhuak thin. He inbiakpawhna hi one-Power receiver atanga power transmitter thlenga backscatter modulation hmanga inbiakpawhna kawng a ni. Backscatter modulation-ah chuan power receiver hian load a siamrem a, chu chuan power transmitter hman mek chu a thlak danglam a ni. Heng tunlaia inthlak danglamna te hi device pahnih te thawhhona tur atana mamawh information ah enfiah leh demodulate a ni. Communication protocol-ah hian analog, digital sound pulses (ping), identification, configuration, leh power transmission te a tel a ni.

Power receiver chu power transmitter-a dah a nih chuan startup sequence pangngai chu hetiang hi a ni:
(1) Power transmitter atanga analog ping chuan thil pakhat awmna a hriat theih.
(2) Power transmitter atanga digital ping chu analog ping extended version a ni a, power receiver ten signal strength packet hmanga an reply theihna hun a phalsak a ni. Signal strength packet chu a dik a nih chuan power transmitter chuan coil chu powered-in a dah a, a hnuaia step-ah a kal zel a ni.
(3) Identification leh configuration phase chhung hian power receiver chuan data packet engemaw zat a thawn a, chu chuan a hriat chian theih nan leh configuration leh power transmitter-a information setup a pe thin.
(4) Power transfer phase chhung hian power receiver chuan power transmitter-ah control error packet a thawn a, chu chuan power a tipung emaw, a ti tlem emaw a ni. Normal operation lai hian signal lian tak tak inthlak danglam laiin control error packet chu 250ms vel leh 32ms velin an thawn thin. Chu bakah, normal operation laiin power transmitter chuan 5S tin power packet a thawn chhuak thin.
(5) Power transfer tihtawp nan power receiver chuan "termination of charging" message a thawn emaw, 1.25s chhung atan a inbiak loh emaw chuan power transmitter chu low-power state-ah a lut ta a ni. QI standard hnuaiah chuan mobile phone, camera, computer leh thil dang dang te chu QI wireless charger hmangin charge theih a ni a, hei hian-scale wireless charging lian tak a siam thei a ni.
