Out of morbid curiosity, I opened the "transPPb.INC" model file, and noticed a gross error. The description says total primary L=100 and the individual inductances of both half-primaries is spec'd at

Guilty, what can I say, but I really can't escape the feeling there was a topic somewhere about some impossibility of having two primaries in a transformer. Maybe there are some crossed neurons

I believe you see why I prefer the multiple winding solution. Having to open the model with a text editor and reloading it in the .asc file is not my idea of immediacy.

The problem with multiple primaries is that it may create conflictss if two sources are too strongly coupled. Indeed, when using multiple primaries, one must make sure the voltages, phases and source

I'll add another vote. I've used LT Spice daily for many years now... The book is excellent even for people reasonably skilled in the art. The sections dealing with magnetics simulations are

in the Fender schemo. Using the "Fender Twin Reverb" example, the output transformer is modeled in the model file "transPPb.INC". Any text editor should do. I also see extra nodes/elements for

Well, I just tried it and you're right, it does work, but I know there was a discussion some time ago (years, probably) about not being able to make a more than one primary transformer in LTspice.

In fact all these examples use a sub-circuit instead of coupled inductors, but I know that coupled inductors work and are IMO easier to edit. To my great shame I must admit I haven't been able to edit

Indeed a dual primary xfmr can be created in LTspice. You need to include all windings in the K statement. There is a beautiful example of tube amp in the Files, in fact more than one: Fender Twin

I don't know if it's possible to simulate a double-primary transformer in LTspice. At least not with inductors and coupling between them. Still, if others have different answers, it would be useful to

I am having trouble modelling an ideal Pull-Push center tap 8 ohms transformer with a 6.7k primary anode-anode impedance in LTspice. Formula: 8*(Np/Ns)^2=7.6k Thus, Np/Ns=30.82/1 Here are my LTspice

i want discrete circuit dirgram of LT1521-5 , i have block digram of LT1521-5 but i dont want block digram as i m working on implant device so i cannot block diagram so, can anybody suggest me from

That's not entirely true: multiplications and divisions are much slower compared to conditional checks, which may be the fastest, computational-wise. Still, I'll stick to what I said related to not

Hello, I want just remember hat models from different vendors are in our section Files. Files > Lib > Linear Regulators Files > Lb > LM317 I haven't checked which is best regarding phase and frequency

Hello all. What is the best model for these chip regulators? I would like a model that accurately shows the phase behavior of PSRR and output impedance, if possible. Otherwise I will probably try to
