Hi
Uff ETD59, lower freq. At 20K you still would get 1kw. And skin effect will be much smaller.

is that true?
if i change the zener diode (connected between output voltage+ and 4N25), i can set up the output voltage. Than if i replace the zener diode by adjustuble zener diode , i can control the output voltage. Thus this project cab be converted the adjustable output voltage smps.
but in here. do i have to change ETD59 transformer?
