1. A voltage converter comprising:

  • an inductor having a first end and a second end;

    a plurality of first switches, connected between the first end of the inductor and a plurality of first terminals;

    a plurality of second switches, connected between the second end of the inductor and a plurality of second terminals;

    a freewheel switch, coupled between the first and the second end of the inductor;

    a first ground switch, coupled between one of the ends of said inductor and a reference voltage; and

    a switch controller, coupled to drive on/off switching of said plurality of first switches, said plurality of second switches, said freewheel switch and said first ground switch, wherein the switch controller is arranged to connect a first one of the first terminals to a different one or more of the second terminals, through the inductor, at different times, and to connect a second one of the first terminals to a different one or more of the second terminals, through the inductor, at different times.
