1. A wireless energy transfer system for transferring energy between a power supply and a load, comprising:

  • a source resonator coil;

    a device resonator coil inductively coupled to the source resonator coil;

    a tunable switching amplifier driven by the power supply and driving the source resonator coil through a source impedance matching network, the switching amplifier having electronically controllable switching elements;

    a tunable switching rectifier driving the load and receiving energy from the device resonator coil though a device impedance matching network, the switching rectifier having electronically controllable switching elements;

    a source amplifier control configured to control a switching characteristic of the switching elements of the amplifier to regulate power extracted from the power supply; and

    a rectifier control configured to control a switching characteristic of the switching elements of the rectifier to regulate a characteristic of an output presented to the load, the rectifier control communicatively coupled to the source amplifier control;

    wherein the amplifier control provides a substantially fixed switching frequency to the switching elements of the amplifier.
