Hi,
Do you see any problem with the attached hi side FET drive method? Its for 2kW LLC converter off 400V.
(LTspice simulation and jpeg attached)
In the following course, in the “Gate Drive” folder, there’s virtually every gate drive method on earth….but I have never seen the attached one documented anywhere on the internet.
