Hey all,
This question is giving me a headache, and I need some practical advice. I need a proof of concept that I can put two separate transformers in series like so:
PRIM1 : SEC1 -> PRIM2 : SEC2 -> output (input x turns ratio1 x turns ratio2)
I quickly ran a spice simulation and got normal results from a single transformer (10:1) and two transformers in series (5:1, 2:1), pictured below:
So the theory obviously checks out, no surprises there. So practical considerations: If both the transformers are rated properly for whatever input/output voltage I have in mind, and they both share the same VA rating, will this really work. Here are some example transformers, a 5:1 and a 1:1 (both rated at 60Hz and 40VA)

Would you feel comfortable putting these two transformers in series as depicted? Applications aside, as I do not know the application for this configuration but am only researching.
Thanks in advance.

PS I'm having difficulty with pictures so Ill attach them.
