Be advised that some Panasonic microwave in the late 90' used switch mode power 
supplies and were light as a feather.  Find one in the junk and check it out.  
They are at about 2300vdc give or take a little.

I have seen very little discussion in the amateur community for HV Switch

advantages of using switch mode power supplies, I'm surprised there has been
no discussion thus far for homebrewing these for amateur use.
