[TCML] HV psu



   Hello,


   I’m interested in replicating David LaPoint’s ‘Primer Fusion’ project.


   This is my first plasma project. I have been working with high voltage
   impulses up to 7kV regularly, but am asking advice on the best way to
   build a psu providing ~500,000v.


   I plan to use a Cockroft Walton multiplier in 20-30kV steps, but need a
   psu to provide 20-30kv to the first stage.


   The main difficulty I’m having is that I want to be able to manipulate
   the:

   1 – Voltage 0-500Kv

   2 – Phase

   3 –  Polarity

   4 – Frequency

   5 – Duty (possibly)


   This would require amplifying the input signal without altering its
   nature.


   It looks like ZVS into Flyback tx’rs will only work on specific
   frequencies, so could a NST work?


   I plan to use an existing system I have with dual channel signal
   generator to control freq, phase, and duty into dual gate drivers/HV
   Mosfets for impulses, but also require a continuous power feed as an
   alternative.


   Any advice would be greatly appreciated.


   Many thanks,


   Ian.
