1. An input or output switching circuit for a power converter comprising:

  • two or more pairs of forward-conducting-bidirectional-blocking switches connected in a first direction;

    two pairs of forward-conducting-bidirectional-blocking devices connected in a second direction to the two or more pairs of forward-conducting-bidirectional-blocking switches whenever the input or output switching circuit is a sparse input or output switching circuit;

    two pairs of forward-conducting-forward-blocking devices connected in the second direction to the two or more pairs of forward-conducting-bidirectional-blocking switches whenever the input or output switching circuit is an ultra-sparse input switching circuit;

    two pairs of forward-conducting-reverse-blocking devices connected in the second direction to the two or more pairs of forward-conducting-bidirectional-blocking switches, whenever the input or output switching circuit is an ultra-sparse output switching circuit; and

    wherein the second direction is opposite to the first direction.
