Abstract: A control system is provided for controlling a power receiving circuit which is configured for receiving power wirelessly and producing an output voltage. The power receiving circuit has a resonant LC circuit including an inductive element and a capacitive element coupled in parallel. The control system includes a switching circuit coupled in parallel to the resonant LC circuit, and a feedback loop circuit configured for regulating the output voltage by controlling duration during which the switching circuit is in a conductive state in each cycle of a voltage developed across the resonant LC circuit.
