For those that are designing 3 winding oscillating ferrite transformers,
ON Semi (www.onsemi-dot-com) has a very good app note AN1679.  Make certain
that you get the second one with the corrected equations. (I'm the one
who pointed out to the author that his orig equations were bogus :)  The
note is probably useful for other ferrite applications, as it allows one
to make an accurate spice model from easily measured parameters.   Rob.
