Abstract:
A charging pad for charging one or more receiver devices is disclosed. The charging pad includes a power drive unit configured to generate a first AC voltage signal having a first frequency and a second AC voltage signal having a second frequency. Further, the charging pad includes a transmitting unit including a single power exchange coil coupled to the power drive unit, wherein the single power exchange coil includes a first coil segment configured to transmit the first AC voltage signal having the first frequency when the first AC voltage signal is received from the power drive unit. Also, the single power exchange coil includes a second coil segment configured to transmit the second AC voltage signal having the second frequency when the second AC voltage signal is received from the power drive unit.
