I saw this on the drain. I don't know why the dead time is not at 0V but something at the level of +-10V ?
I tried to put some load on the PS but experienced big voltage drop say 2V from 30V with 15W. There is a problem somewhere.
May be you could tell me some clue about it so I can experience further with the project. I have 100nF and 50Ohms as snubbers which are dissipating a lot, getting hot not to touch.
I didn't think this thing will be so complicated getiing it run but since I read lot of stuff in the forum here I realised It is not simple.
