Thanks, in that case i'd say they (back to back zeners) are needed for us. Our GDT is just three coil, no sandwich winding. And tracking to the fet near the txformer is short, but long to the other of the leg pair.zeners not needed - only for GD Tx's with a lot of leakage and long lines to the G-S ...
Thanks, though ours is the simplest rendition of it....and so voltage drive level varies with duty.GD level does not have to be tied to duty cycle - for a bridge driven GD tx, or or the fwd driven GD TX driving a diagonal pair ....
Thanks.....there's a cap in series with the single pri.....but no cap in series with the two secondaries that are on the same core.too small cap in series with GD Tx
Thanks, well ours is half that power, and just uses one of these pulse transformers for each leg..for 1kW, it needs to be designed and laid out by engineer with > 10 years experience
