Hi,
I build a HiEnd audio power amplifier with push-pull transformer and FETs. I will use the Hammond 1650-F audio transformer and wanted to simulate the transformer in Multisim in a correct way. But the Multisim uses the "one primary coil - more secondary coils" models but a push-pull audio transformer has two primary coils which are excited parallelly.
This is why I started to develop a general mathematical model for transformers where there are no primary and secondary coils but only coils and any or some (or even all) of them can be excited parallelly.
Based on the mathematical model I could build the SPICE model of the 1650-F transformer (or any other type if I needed).
My question is that wich is the best category in this forum where I can share my result for those who want to develop the SPICE model of their own special transformer.
The description is in a Word file which is now attached but I am not sure that this is the best place.

Здоровья!
А чем вас не устраивает такой универсальный трансформатор (собственные сопротивления и ёмкости обмоток можно ввести дополнительно)

You are right, as I investigated the Multisim transformers now, I realised that I was stupid.
It was a delusion to beleive that the transformers of Multisim can be excited at only one "primary" coil and no more. And that the coils are not coequal.
I don't know when and why this delusion evolved in my mind but it could be more years before.
You can forget it.
Though there is a good result for me: I have a perfect knowledge about the theoretical work of transformers and a usable model.
Bye

Раз вы такой умный, создайте модель для трансформатора по
