Transformers are broken

Can somebody please tell me why it is impossible to get 240v 50a from a 24v source using a transformer. I have tried every configuration of primary and secondary windings and inductance I can think of but the absolute BEST I get is 100v on the secondary side through a 4.8ohm resistor. I've even tried adding extra transformers which do help to up the current but you quickly hit diminishing returns. What in the world am Missing

Swap the resistor out for a Volt meter, on the transformer make the coupling 1, P1=1 / P2=13,5 , so it makes 1:13,5.. you get your 230v.. then play with the P2 for your voltage

Right, I know I can achieve the right voltage, but I can't seem to achieve the right voltage AND current

After studying your circuit for a long time, I think the key to the mystery is the primary and secondary coil resistances. EC transformers are not ideal and (among other things) have 0.1ohm resistances in the coils. As current flows through these, a voltage drop is created. The current your circuit would require is high enough that the voltage drops and the secondary load exceed the 24V input. This is why (in my opinion) it is impossible.

Yes, you are on to something by placing transformers in parallel. Check out this circuit: https://everycircuit.com/circuit/5702325926363136
