Hi Ken...

rectifying  15KV is easy in the low amp rating  ( < 1A)  but handling 
several amps at 15KV is a whole new story ( 105KVA ...  wish I had that 
much power to the shop)    

you will need 100 diodes (1000V 1A )...   25 per side ( 4 sides) for 
full wave...  this is how they rectify some X-Ray machines...  

series 25 per side and configure as a full wave ...     this will handle 
the load and voltage up to .95 A -at- 15KV...  but hey   thats still 14KVA 
  ....
