monster!

hi! have you ever tested this amp?

 

[Mikael Abdellah]

where do you intend to find a ~45kVA transformer or ~30kW SMPS ?

Re: monster!

yes, tested this amp.

Just .... Why ?

 

[Jan Dupont]

Makes a nice welding machine

 

[jacco vermeulen]

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. ?)

 

[djQUAN]

I want to see pics of the actual amp.

 

[cviller]

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.

KCK
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

 

[GRollins]

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.

Yes! comparing those circuits, it's very different with each other specially the drivers.

 

[Eva]

Nah, it's not that bad. Since inverting and non-inverting inputs are swapped, this circuit will act only as a big power latch

 

[jacco vermeulen]

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.

 

[huy5005]

How about show us the Transformer????

 

[kck87]

I sorry.
I no speak english and I no write english.

 

[peranders]

... then the thread is more or less closed

 

[Netlist]

Not necessarily, I think our Turkish friend is doing just fine.

Kck, just try to write in your own words, you will be surprised how easily people will understand you.
