1. A power factor corrected rectifying circuit comprising:

  • a power input port for receiving an AC power source having an input voltage and an input current;

    a power output port;

    a first rectifying means for providing a first rectified current path between said power input port and said power output port;

    a second rectifying means for providing a second rectified current path between said power input port and said power output port, said rectified current paths being capable of simultaneously conducting current;

    a current delay means in said first rectified current path for delaying the coupling of current through said first rectified current path such that the waveform of the input current at said power input port approximates the waveform of the input voltage at said power input port; and

    a current combining means for coupling the first rectified current path and the second rectified current path to said power output port.
