    Just wondered if LT spice can be used to describe an autotransformer - and see
    the effects on its output with changing input frequency (& saturation of the
    xfmr)? If it's not built it and you have designed one, I very much appreciate a

    ps I suspect this is either very simple (just join 2 inds together) or very
    difficult) :)

    Just connect the two inductors in series, and define the coupling
    coefficient between them as you would for any transformer. There's no
    difference between a single tapped winding, and coupled inductors in series.
  3. There is a Yahoo discussion group dedicated to LTspice, called
    "LTspice/SwitcherCAD III"

    I suggest you join this group and get all the hand holding you need to
    pursue this. You might also search out message # 2084, and do some
    other related key word message searches.
