Abstract
Exemplary embodiments are directed to controlling impedance. A wireless power transmitter for controlling impedance comprises a transmit circuit configured to wirelessly transmit power to a plurality of receivers, each having a load resistance, within a charging region of the transmit circuit. The transmitter also comprises a controller configured to request each receiver of the plurality of receivers to adjust its load resistance to a value that achieves a target total impedance as presented to the controller.
