Abstract
A method includes determining, by a base station including a number of transmitting coils, a first number of mutual magnetic parameters, each mutual magnetic parameter being associated with one of the transmitting coils and a receiving coil of at least one receiving coil associated with at least one electronic device remotely located from and to be remotely charged by the base station, determining a plurality of control signals based on the first number of mutual magnetic parameters, each control signal being associated with a corresponding one of the transmitting coils, providing each control signal to a driving circuit coupled to the control signal'"'"'s corresponding transmitting coil, and using each control signal to cause the driving circuit coupled to the control signal'"'"'s corresponding transmitting coil to cause a current with a magnitude and phase determined from the control signal to flow in the corresponding transmitting coil.
