Hi Sven,

A square wave voltage as input gives a triangular wave of current.

"I wanted to set a choke on the push-pull center tap so that the current can be limited if the transformer winding through saturation or fault still has at least an impedance so that the mosfets are not destroyed, what do you think of that?"
An inductor certainly will limit the current of a square wave. An electronic fuse or a crowbar circuit that blows a normal fuse would protect even against excess DC current.

The snubber protects against over-voltage spikes.

 Hi Ole,

since I have a bifilar winding on the 3 phase transformer on each leg, I can wire the windings so that I can induce a square wave in push-pull mode, maybe ping, with a short strong pulse, that's my plan.

I have found a pdf for Energy Recovery Snubber here as in Figure A, I wanted to build that.
