Has anyone else had trouble with the performance of a non-linear transformer model created in PSpice ? I created the core model OK and used the K model to couple the windings and the CORE. With one winding excited, I get transformer action and non-linear core excitation. However I always get coupling = 1, no matter what I set COUPLING to.
I thought you could model leakage inductance, as you still can with the linear transformer model.
