I'm trying to find the quickest way to account for saturation of a transformer in LTSpice.
The reason I need to include saturation in the model is because it's a blocking oscillator.
There's a nonlinear transformer model in the library at the yahoo group (the Chen model), but it includes a couple of parameters related to the hysteresis loop.
I don't know what I would use for the hysteresis parameters and would like not to have to use those extra parameters, if at all possible. No B-H loop, just a transformer that can saturate, but has no hysteresis.
There's an "arbitrary inductor" model that takes saturation into account while ignoring hysteresis. If I could use this model in a transformer by simply coupling two inductors it would make my life easy, because I have the volt-seconds figure for the trafo I intend to use.
This wiki shows the inductor model:
So I tried putting two arbitrary inductors in my schematic and coupling them. LTSpice tells me I can't use coupling with arbitrary inductors. Same result when I try to couple an arbitrary inductor with an ideal inductor.
So I'm still at square one. Do I have to use the Chen model, or is there an easier way to do this?
