The gate drive transformer is necessary because the source pin of the upper mosfet is not at ground.
But I think there is a problem with the transformer driver. Pins 11 and 14 of the SG35245 are both emitters. You are putting +12V alternately into each side of the transformer, but there is no ground node to complete the current path.
The easiest way to fix this would be to add a center tap to the GDT primary.
First off, I can't believe your only 10 or so miles from me, I'm in Orem and grew up in Provo. Thank you for your reply.
So, can you config the Transformer for me, I'm not an engineer, I'm just a noob. I like putting things together and making them work, sort of beating them softly into a powder puff with compliance
I totally enjoyed my day's off working on this, I really want to build this and make it work well and give them as gifts to 2 of my friends. Both are well educated and schooled on electricity and the nasty's of it, if on the wrong side of the flow.....wink.
A schematic would be really nice, I don't care what it looks like, hand drawn, really I would appreciate it. I will need to take care of the signal and make the right waveform.
Thanks, Chris

Edit: Oh, and I did see a center tap, on another Plasma Speaker but, the Chip was driving directly. No, GDT. I can't see how I could implement this? but I will try anything.
FYI, I bought at least 10 of everything..., just for this reason.
Edit:Edit: Now, this reminds me of another person trying to complete this project. They had completely lost the top Mosfet and couldn't get it to work right. (That explains a lot)
