1. A single-stage power converter, comprising:

  • a. an inductor;

    b. a first side of the converter comprising;

    i. a first capacitive means connected in parallel to the inductor,ii. a first port connected in parallel to the first capacitive means, andiii. a plurality of first switching elements having a selectable open state and closed state, the first switching elements linking the first capacitive means and the inductor in such a manner that when the first switching elements are closed, a conductive loop is formed by the first capacitive means and the inductor;

    c. a second side of the converter comprising;

    i. a second capacitive means connected in parallel to the inductor,ii. a second port connected in parallel to the second capacitive means, andiii. a plurality of second switching elements having a selectable open state and closed state, the second switching elements linking the second capacitive means and the inductor in such a manner that when the second switching elements are closed, a conductive loop is formed by the second capacitive means and the inductor; and

    d. a system controller able to control the state of the first switching elements and the second switching elements.
