Original poster: Skip Malley <skip@xxxxxxxxxxxxxxx>I fully agree with a couple of the replies to this thread that the leakage inductance of the standard E core Gate Drive Transformers is too much. That is why I don't use them in the switching power supplies that I design. Apparently, some people are not aware of the toroid GDTs that are available You can purchase toroid wound GDTs. A couple companies make these. They have much lower leakage inductance. I have some leftover from a power supply project. Click on this link http://www.lse.com.tw/upfiles/spec01125457782.pdf to see the specs. These have 1/10 of the leakage inductance of the normal EE core transformers. What kind of leakage inductance has anyone else had when winding your own?
I have some of the ones listed in the listed link above. If someone would be interested in trying one, I would love to let you borrow one.

Winding a GDT on a toroid, with a twisted group of wires is very easy to do, and the results are usually very good. You can even make your own customized shielded wire packs for even higher coupling between windings.
