1. A circuit comprising:

  • a wireless power signal input to provide a wireless power input signal;

    a switch network coupled to the wireless power signal input, the switch network comprising switches arranged to rectify the wireless power input signal to provide a wireless power output signal;

    control circuitry in communication with the switch network, the control circuitry configured to;

    respond to a current wireless power transfer operating goal by determining an impedance to implement;

    purposefully introduce the impedance to the wireless power input signal via the switch network; and

    cause the switches to rectify the wireless power input signal to produce the wireless power output signal.
