Abstract:
1. A system for providing positioning freedom, and support of different voltages, protocols, and power levels in a wireless power system, comprising: a base unit having one or more transmitter coils, which transmit inductive power to a receiver coil placed close to the one or more transmitter coils and configured to receive power therefrom; a switching layer having magnetic properties and covering the one or more transmitter coils, so that, a microcontroller within the base unit or the mobile device, for support of different voltages, protocols, and power levels, including determining by the base unit, for the mobile device to be charged or powered, a charging protocol from within a plurality of different charging protocols to be used, and one or more voltage and power level requirements for the mobile device; and a regulator for regulating, by the mobile device, power received at the receiver coil, including communicating between the receiver and the base unit, using the particular charging protocol, information used by the base unit to make appropriate adjustments to provide a required output voltage, current or power at the receiver output; wherein multiple mobile devices, batteries or receivers with different voltage or power level requirements can be simultaneously charged or powered by the base unit.
