Hi CJ,

I found a method that I have used with success.  I have put the 
theory and procedure on my site at
http://home.earthlink-dot-net/~electronxlc/difmodel/coupling.html

My method treats the primary and secondary coefficients of 
coupling as two different values.  It does not simplify the 
transformer model by putting all the leakage inductance on the 
primary side.  These simplifications can be made afterwards if you 
wish.
