LT Spice autotransformer

[Dave]

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
copy.
Thanks

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.

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.
