1. An improved resonant converter for transferring electrical power between a first, second and third input and a first, second and third output, comprising:

  • a series resonant circuit including a capacitor and an inductor connected in series;

    first, second and third bidirectional input switch means connecting the first, second and third inputs to said series resonant circuit, respectively;

    first, second and third bidirectional output switch means connecting the first, second and third outputs to said series resonant circuit, respectively;

    first, second and third input capacitor means connected to the first, second and third inputs, respectively;

    first, second and third output capacitor means connected to the first, second and third outputs, respectively; and

    means connecting said first, second and third input capacitor means to said first, second and third output capacitor means for enabling only six bidirectional switches to interconnect the first, second and third inputs to the first, second and third outputs.
