摘要:
Systems, methods and apparatus are disclosed for a dual mode wireless power receiver. In accordance with on aspect, an apparatus for receiving wireless power is provided. The apparatus includes a first coil configured to wirelessly receive power from a first transmitter configured to generate a first alternating magnetic field having a first frequency. The apparatus further includes a second coil configured to wirelessly receive power from a second transmitter configured to generate a second alternating magnetic field having a second frequency higher than the first frequency. The second coil is positioned to enclose the first coil. A first coupling factor between the first coil and a coil of the first transmitter is higher than a second coupling factor between the second coil and a coil of the second transmitter when the first and second coils are positioned within respective charging regions of the first and second transmitters.
