Hi all
i have found this schematic
(the second one, the bad quality)
it was said that this is a low noise, high eff. adjustable lab smps with adj. current limiting
so i decided to redraw it and mod it
i am quite lazy so i just copied the the values
the transformer primary will be 22 turns CT on etd49 core it will work at 200khz
i was too lazy to add the output filter
(the first, high quality)
the IGBT is IRGPS40B120UP

so, is it going to work
if not tell me how to do it

doesnt look too good
you appear to have the input 120V connected directly to the output

why redraw ( and incorrectly) an already working design ?

I don't think you are going to get 2.5kW out of a two-transistor forward converter.

At least, we never could.
