Abstract
A control circuit for an inductive power outlet configured to transfer power to an inductive power receiver includes a resonant circuit having a characteristic resonant peak and connected to a primary coil configured to inductively couple with a secondary coil of the inductive power receiver, a frequency driver operable to provide a driving voltage oscillating at an operating frequency higher than the characteristic resonant peak of the resonant circuit across the primary coil, a magnitude detector operable to monitor primary coil voltage, and a data demodulator operable to detect modulated peaks in primary coil voltage indicating that a communications modulator of the inductive power receiver has transitioned from a first state to a second state. The communications modulation determines a characteristic frequency of the peaks and extracts modulated data sent in communication signals from the inductive power receiver.
