Curent transformer spice model?

[Clarence_A]

Does anyone have a web reference to a spice model of a current
transformer or a site where creating such a model is discussed?

Also, I will eventually need a Saber model of the same part.


Thanks to the serious engineers on this list!

MacF only had an Ls, which could be assumed to be complex
to allow for (inphase) iron losses, but I found it easier
to add a separate Rc for core loss.

The model with Rc is more accurate, but usually Rc is high enough to be
negligible. YM obviously V'ed.

The good news is that nothing is compulsory.

The core loss was about the right order for that
material and volume, (Telcon, HCR), at 400Hz.

There was also a measurable core loss with ferrite
at 15KHz, but I must admit to pushing the Bmax a
little high.
