Abstract
A power transfer system for providing charging power to a power receiver is disclosed. The system comprises a hardware controller circuit, a first filter circuit, and a second filter circuit. The hardware controller circuit is configured to determine a first frequency for providing power from a first power transmitter to the power receiver via a first wireless field. The first filter circuit is operationally coupled to the hardware controller circuit and has a first frequency bandpass configured to pass a first driver signal for generating the first wireless field at the first frequency. The second filter circuit is operationally coupled to the hardware controller circuit and has a second frequency bandpass configured to pass a second driver signal for generating a second wireless field at a second frequency that is different from the first frequency.
