1. A power converter for converting an input voltage signal to a DC output voltage signal for driving a DC load, said power converter comprising:

  • a first set of input terminals for receiving an AC input voltage signal;

    a second set of input terminals for receiving a DC input voltage signal;

    a single, shared power transformation circuit directly connected to said first set and said second set of input terminals, said power transformation circuit comprising;

    a first voltage stage coupled to said first set of input terminals;

    a second voltage stage coupled to said second set of input terminals; and

    a third voltage stage coupled to said first and second voltage stages for convening said input voltage signal to said DC output voltage signal, said third voltage stage further including a set of output terminals connected to said DC load; and

    ;

    a controller driver connected between said first and second set so input terminals and said first and second voltage stages for during a selected one of said first and second voltage stages.
