Just curious, why isn't anyone considering GTO thyristors for this?
ok they do eat a lot of gate current, and switching time is around 10us
or longer, but, for "spark gap" replacement it should work very well. I
mean, something like 4kV 3kA-continuous is possible. GTOs being older tech
than igbts they should be comparatively cheap to get...

cheers,
