1. A power converter, comprising:

  • a DC port;

    an AC port;

    a central resonant circuit;

    a set of controllable “

    DC”

    switches electrically communicating with said DC port and said central resonant circuit;

    a filter electrically communicating with said AC port, said filter generating a voltage during operation of said converter;

    a set of “

    AC”

    switches electrically communicating with the central resonant circuit and said filter;

    a switch control circuit responsive to phase order, to secondary-to-tertiary time percentage, and to inversion time percentage for controlling inversion and normal conduction times of said DC and AC switches; and

    a modulator responsive to said voltage at said DC port, to said voltage of said filter, to current command signals, and to the voltage at the AC port, for generating the phase order, inversion time percentage and secondary-to-tertiary time percentages.
