Could you please send us pointer to reference and model used for the 
transformer? 

I believe it will be simpler to use C++ model.

Some possible link (the domain is huge). It will be easier for you to use a 
spice like schematic.

BTW could you please shut up the following disclamer. Posting to a public list 
this kind of stuff is at least void (in a law sense).
