Abstract:
A power transmitter is configured for transmission of wireless power, to a wireless receiver, at extended ranges, including a separation gap greater than 8 millimeters (mm). The power transmitter further includes a coil configured to transmit the power signal to a power receiver, the coil formed of wound Litz wire and including at least one layer, the coil defining, at least, a top face. The power transmitter further includes a shielding comprising a ferrite core and defining a cavity, the cavity configured such that the ferrite core substantially surrounds all but the top face of the coil. The power transmitter includes at least one magnet, the at least one magnet configured to attract at least one receiver magnet when a power receiver is proximate to a surface associated with the power transmitter.
