1. A synchronous switch circuit, comprising:

  • an inductor for producing an alternating current voltage in response to a received changing electromagnetic field;

    a synchronous rectifier comprising a first and second high side switch and a first and second low side switch that rectify the alternating current voltage to produce a direct current voltage;

    an energy storage device for storing energy from the direct current voltage; and

    control circuitry for controlling the first and second high side switch and a first and second low side switch in response to a state of the alternating current voltage signal.
