Hey All,
I'm trying to enter transformers into a spice model and I need a little help. First off, I know how to do the spice directive to make two inductors into a transformer. For a center tapped output transformer primary do you use two inductors connected at the center tap?
In the L1 dialogue box henries is easy. For the peak current line is that the peak current of the circuit or the transformer? Also, is the series resistance and the parallel resistance the resistance of each winding and it's corresponding resistors in the circuit? Likewise, the paralell capacitance also within the circuit?

Couple 2 inductors by the K spice directive: "K1 L1 L2 1" will fully couple L1 and L2. Center tapped XFMR is best done with two inductors, coupled and connected in series, right. BTW: Take care of the winding direction (dots)!
