That's a nice design and a step in the right direction.
Pls write some more info about the DC-DC connection transformers,  e.g. what is the capacitance between their primary and secondary windings?  Are they regulated?  Power, switching frequency, etc...

I am afraid you design will be lost on most people here, because it looks complex and expensive ...despite that it solves most FET driving problems and even saves money on burned up FETs in the long run and allows to do fast (μs) bidirectional solid state relays ...and the general versatility of the thing!
If it had drain overcurrent protection included, then only drain overvoltage and dv/dt could kill the FETs.


P.S.
Were you ever tempted to do gate charge recovery or HV gate pulse preemphasis?

Any of Analog Devices Adum drivers are suitable ?

The ones with 5kV rating and 13ns propagation delay seem only a little worse then the ones from SilconLabs.  I didn't study their datasheets to find out whether they work all the way down to DC or whether they have a minimum frequency limit.
The 5V power supply limit means that you'd need more voltages on the secondary side to power them...because FET gates like up to ±20V.

You still need fast and high current FET drivers to go with these ADUM isolators.

over 1000 pages...... does this actually work? or does it seem like it works hence the 1000+ pages of discussions

For those that truly believe it works for others (after having read all the posts and seen all the videos from the 1000+ pages), have faith that it will eventually work for them.

Don't let's go into the Fraud of Faith Religion and Bolxtics on here, please !
we don't need the mind games, just focus on out target ! many thanks.
