Hi Max,

Are you sure you need 40kV!!  MMCs do not have to be made to take higher
voltages like old homemade caps were.  Noramlly 20kV would be just fine and
cost 1/4 as much which would hit your cost target.  What is you peak or 1.4
x RMS voltage?  that is the voltage you should rate an MMC too.  Any higher
and your wasting money.  See also:
