Hi All,
I am an enthusiast with a basic understanding of electrical engineering, and I would be grateful for your support.
This is my first post on this site, and I would appreciate your help. I'm currently working on implementing an LTSpice model to emulate both single-ended and push-pull transformers. I’ve come across some research that provides a high-level overview of how to model the magnetic core using a Gyrator-Capacitor approach. For more details, you can refer to pages 6 and 7 of this document:
https://asp-eurasipjournals.springeropen.com/counter/pdf/10.1155/2011/347645.pdf
In the attached files, you will find a library for modeling a gyrator-capacitor, along with single-ended and push-pull transformer models and examples.
The parameters in xformer.lib were calibrated using a tool I developed. I have successfully implemented this model in a state-space simulation software I built, but I would like to adapt it for LTspice to validate its performance.
When I run a symmetrical signal test—using the example from the Push-Pull Transformer (Gyrator-Capacitor).cir file—I observe that saturation behaves as expected for the secondary tap, S1, but not for the primary tap, P1. In this example, the primary winding consists of 200 turns (100 per tap), while the secondary has 100 turns. Given this configuration, I would expect the voltage and saturation effect at P1 and S1 to be identical, but this is not the case.
I would greatly appreciate any feedback or corrections.
Thanks!
