摘要：

There are 2 wireless power standards for the mobile device market: Qi standard and AirFuel standard with frequencies of hundreds of kHz and 6.78 MHz. This paper presents a dual-band wireless transmitter operating at both 200 kHz and 6.78 MHz. A dual-band reconfigurable PA with Class E and half-bridge modes is introduced to decrease the size of transmitter. Meanwhile, the eddy current loss model of parallel connected dual-band coils is established to provide guidance for coil design. Finally, a dual-band charging pad with specially designed "decoupling ring" is proposed, which can effectively reduce the extra loss of dual-band operation.
