    Dear All

    How we can do AC sweep analysis for the transformer in LTSPICE.

    Hi,I use LTspice alot. It doesn't have a transformer model, but you can build one with inductors (L) and the mutual inductance circuit element (K). Do AC sweep as you would a circuit. The results will only be as good as your model. You can also import a model from the xfmr manufacturer if you can get it. The results would be much more accurate.Regards,Ifixit
