A method that works with many switchmode power supplies: Build a
rectifier/filter box to insert between the 400 Hz mains and the switcher.
In other words, supply the switcher with DC. This generally works even
with
switchers that include PFC. It doesn't require much capacitance to filter
400 Hz.

** DC mains supply was abandoned about 100 years ago - for darn good
reasons.

Even then it was only 240V DC not 350 V DC !!!

IMO - the fire safety hazards and risk of accidental misconnection of
transformer loads are too great to even contemplate this option.
