1. An auxiliary inverter for use with a main inverter of a transmitter of a wireless power transfer system, the transmitter configured to transfer power to a receiver of the wireless power transfer system via electric or magnetic field coupling, the auxiliary inverter comprising:
a coupling element;
an output network electrically connected to the coupling element; and
an adjustable power source electrically connected to the coupling element via the output network, an input voltage to the coupling element based on a detected signal,
wherein the coupling element is configured to induce a voltage in the main inverter of the transmitter of the wireless power transfer system to manage reflected impedance at the main inverter, the induced voltage based on the input voltage to the coupling element.
