Transformer with full wave bridge.

Hello,

I am attempting to simulate a power supply circuit and I am stuck on the input transformer.  I am attempting to utilize K Linear with two inductors.  The voltage conversion seems to work fine i.e. the voltage step down is correct (190V input at 1200Hz and I get 15V @ 1200 Hz output), but as soon as I add a full wave bridge recitifier everything goes bad.  I go from getting a nice sine wave out of the transformer with peaks at 15V, to a severly clipped and rounded square wave with peaks at 500mV. 

Has anyone successfully done this type of simulation or know of an example for me to look at to see where I am going wrong?

Can you share your circuit? Generally speaking, a properly modeled transformer output would not be impacted by full bridge and load. Yes, i have successfully simulated such circuits.
