An externally hosted image should be here but it was not working when we last tested it.

It's also some of the welding machines where to find such frggn transformers(3-Ph)
(should this humpty-dumpty thread not be seated in the quasi-c corner of the Solid State dep. ?)

Doesn't it sound like he has only tried the small version and that he is now building the big 22kW version?
I think he might get in trouble balancing the push pull with mosfet driver for the one half and bjt for the other... what do you guys think?

pic shown looks like the lower power version, it has lesser number of output transistors. please show us the big one. if this is real, its very suitable for street party, we can avoid many numbers of amp.

The amp you posted in your first post is technically as well as theoratically incorrect. There are insane mistakes in it such as
IRFP250 200V FET connected to +/-150V rails
No precise biasing and totally asymmetric drive to FETs.
If its a joke than ok, if its not a joke than you have made a joke of yourself 🙂

I think it's safe to say that this is a...shall we say...speculative circuit.
Personally I find it interesting that there's one bipolar driver and one MOSFET.
I'm not sure I understand why Anthony Holton's schematic was posted. It doesn't seem to bear any relation to the schematic in the original post.

Nah, it's not that bad. Since inverting and non-inverting inputs are swapped, this circuit will act only as a big power latch 😀😀😀
Eva,
KCK forgot to add that you are supposed to put -145V on the inputs before hitting the power switch, and use 25W resistors in the Vas to achieve the nicest blast.
