1. A method for low-ripple transfer of power from a system-side circuit to a line-side circuit connected via a two-wire interface, comprising the steps of:

  • transmitting a forward pulse stream from the system-side circuit to the line-side circuit during a first time period;

    rectifying the forward pulse stream in the line-side circuit to produce a first rectified voltage during the first time period;

    transmitting a reverse pulse stream from the line-side circuit to the system-side circuit during a second time period;

    providing a supplemental pulse stream during the second time period; and

    rectifying the supplemental pulse stream in the line-side circuit to produce a second rectified voltage during the second time period;

    wherein a rectified voltage is produced during both the first and second time periods.
