K6- Switching power supply

[microsim444]

I wonder if any one worked and succeeded into the K6 switching power supply,

www-a-and-t-labs.com


I built this supply from scratch, but the mosfets burns at 3 amp draw .
I dont know why!?


I connected my amplifier, put some music at high volume 4 Ohm load.

30 seconds playing. watching the multimeter, at 3 amps , the fuses blown, check mosfets, they are gone!!

they get very hot at low current draw.


Any comments?

Try to make some driver enhancement I don know why, but this topology with transformer driver is not good.

There are several bad reports on this particular power supply. Do a search and you can follow the threads.

this design is trick, it will not work unless you buy the original transformers, (I dont think it will work either)


i am moving to a new design now, IR2110,
