Abstract
In various embodiments, a power transmitting device includes a wireless power generator configured to generate a wireless power signal. A transmit resonator is configured to transmit the wireless power signal via a transmit magnetic field to a power receiving unit. The transmit resonator includes a transmit coil configured to generate that transmit magnetic field in response to the wireless power signal. At least one variable magnetic element is configured to adjust at least one property of the transmit coil by varying a reluctance of the at least one variable magnetic element in response to at least one control signal. A processing device is configured to generate the at least one control signal to select the reluctance corresponding to the at least one property of the transmit coil.
