1. An electric power system, comprising:

  • N electric power sources, N being an integer greater than one;

    N switching circuits, each switching circuit including an input port electrically coupled to a respective one of the N electric power sources, an output port, and a first switching device adapted to switch between its conductive and non-conductive states to transfer power from the input port to the output port, the output ports of the N switching circuits electrically coupled in series and to a load to establish an output circuit;

    wherein each of the N switching circuits uses an interconnection inductance of the output circuit as a primary energy storage inductance of the switching circuit.
