1. An interleaved power converter system comprising:

  • a power bus having a first node coupled to a source of power and a second node coupled to a load; and

    a plurality N of power converter slices connected in parallel with said power bus for providing current thereto, each of said slices providing approximately of a total amount of current flowing through said power bus, each of said slices comprising,at least one switch coupled to said power bus;

    an inductance having a first terminal coupled to said at least one switch and a second terminal coupled to said power bus; and

    control means having an output for controlling the opening and closing of said at least one switch to control an amount of current that flows through said inductance as a function of a difference between (a) a first signal that represents a magnitude of a voltage potential of said power bus and (b) a second signal that represents a combination of a magnitude of an average current flowing through said power bus and a magnitude of a peak current flowing through the inductance.
