I had that thought, too. I myself have not the least practical experience with
this stuff, only a basic Idea how it works, but I always wondered how
hard it would be do design a10 to 15KV 1 to 5 or 10 KVA SPSU,
with modern power electronics this can't be a too big problem and
when running a DC output, RF troubles should be solvable. The only
point I am not sure of is, what could be the core of any output
transformer.... are there any big enough ferrite cores around?
Would certainly save a lot of wight and power controll could
easily incooperated.
