Hi,
I'm looking for some help on this SMPS Circuit,
http://danyk.cz/reg60v.png
I've built the circuit on a PCB and everything works fine Voltage regulation etc...
But as soon as I attach a load (A 60 Watt 12V Light Bulb) in this case the IGBTs short out and die, all 3 legs are shorted together.
I tried with 600v Mosfets as well but the same still happens.
Any Help would be much appreciated.
