Summary:This paper describes the design, fabrication, and measurement of a magnetic resonant wireless power transfer (WPT system. The proposed parallel resonant circuit power amplifier is combined with a compact wireless transceiver coil (receiving coil diameter 7 cm, transmitting coil diameter 16cm), so that the wireless power transmission system has the ability to transmit about 1 Wpower at 10 cm, and has no change in load sensitivity, and the WPT system could can receive power from LED to linear resistance. The experimental results show that the transmission efficiency of the system is as high as 42%. This article provides a novel and concise way to achieve wireless power transfer, which may help to popularize wireless charging in the future.
