Abstract: A wireless power transmitter that provides wireless power via a magnetic field includes electrical connections for a driving signal and a plurality of coupler loops that divide the current generated by the driving signal. The transmitter can be tuned to provide a distributed magnetic field that is more evenly distributed over the transmitter pad. The currents through different coupler loops can be controlled by the relative impedances of the coupler loops. The coupler loops can take on various shapes, such as substantially concentric circular paths and they may overlap. Impedances can be designed using one or more capacitances. Capacitance between coupler loops can be provided. Feed capacitors might be provided at the electrical connections.

Abstract: The present disclosure pertains to wireless chargers. In one embodiment, a 2×2 array of conductive coils produces magnetic fields. Adjacent coils receive current having different directions to cancel magnetic fields around a periphery of the array. A wireless charging platform may include at least four such coils. Regions between and above the coils may include magnetic fields approximately parallel to the surface of the platform so that electronic devices may be charged while standing up during operation by a user with reduced exposure to magnetic radiation. An electronic device may also be placed flat on each coil for charging.
