Good job. Two suggestions: after you finish the windings, soak the bobbin with the coils in varnish and allow it to dry completely before you insert the lamination. Otherwise the coils can make some noise. second: The lamination stack should be pressed in a vice and bolted very tightly otherwise some magnetostriction hum will come.
if m not wrong, each tranformer is a step up 12v to 220v. Just connect 2 primary of them in series to make 24v and connect 2 secondary of them in parallel. No need to rewire
Increasing the core cross section does not really help you in fact its more likely to hurt histeresis. You can keep the same turns ratio on a smaller core and you also increasr the DC resistance of windings because for the same turns ration you need a whole lot more wire. This makes no sense because you can fit only so much wire on the core that this pointless. There is a reason why big or any transformers aren't of this shape. Paper tape is NOT a proper insulator btw. You either use capton tape or spacers. I wonder if there are actually real engineers watching stuff like this and I want to know if they are cringing as much as I do on this stuff. Testing a transformer by shortimg the output? Yeah that shows us real performance values. VA of the transformer, apparent power and all that techy stuff that could save you a couple of dollars just by designing a transformer that won't have extreme losses
hello mr i am an intern i am in ivory coast. I wanted to know how to determine the wire diameter of a primary and secondary inverter transformer. example case of a 1000w transformer

Nice computations but you did not show how you get the gauge number of wire in primary and secondary how annoying...

Wrapping the bobbin with masking tape is a poor choice - use Mylar tape, it’s designed for high temperature and high voltage.
That mains power lead is the scariest thing I've ever seen 😢
the iron core is too large The wire should be 2.2 mm if the wire (primary) 1.2 then the iron core is 18cmm2 (otherwise there is little space Üdvözlet!
Dude this type of transformer you've made is less efficient than 3 transofrmers you've just used to make this one.

I support you
You are creative, sir ... I watched this video until it's finished ...👍👍
Muchas gracias!!!el truco de poner cinta por cada pasada de alambre en los extemos de la formaleta me ayudo a que el bobinado me ocupe menos espacio
Very good! I have done this o lot of times 😁.
Mujhe technical video achi lagti hain main aisay kaam sekhna chahta hoon.apki video se buhat kuch sekhne ko milta hai.thank you.
I learn many things about transformer making .this is one of the best channel I found from youtube about electronics .thanks for your videoes sir .
Muito bom.
Ficou ótimo bom trabalho no trapo
super bro good idea before iam also done same this for 45 0 45 v amplifier
Great idea you have! Thanks for share!
