While followed a thread "low inductance output stage construction", I decided to make similar set up and test. Along the way lot of things get improved and then come a question of good gate driver design. Decided to go with Zombiess design. Here is preliminary schematic with little modification. Design differs from original design in this post https://endless-sphere.com/forums/viewtopic.php?f=30&t=58341 in couple of things. I didn't used current boost stage with output transistors and added bipolar power supply.
Some application notes which used with a lot of info.

In original design driver was used with IRFP4568.
Concerning diode DZ1 I used same value of 7.5V. How this value was choosed? I understand that this value is involved in 2-level turn-off feature and Vgs voltage first falls to this value and after some configurable time falls to zero or negative votage (depends which power supply is used for driver). What are pros and cons using zener with higher value for example 10 V?
