3-phase is cool, but also obligating, since noone should ever draw more
than, say, 35 amps from one phase only, since this will skew the grid.
I think the 3-phase rectified supply would be more used, if the function
of the charging choke was better understood.
Would you please explain how to determine a proper sized charging choke
in a system, where transformer voltage and capacitor size is already
given, so that it results in the desired doubling of the voltage across
the cap/vs the input voltage, while keeping the current from the
transformer to the gap during ringdown low enough to allow quenching of
the gap without making a rapid recharge of the cap impossible.
