HV Chamber: electron capture question...

Not open for further replies.


New Member
made a clear PVC chamber, 4" dia.x 10" long. with 4 sections, each section seperated by 2 plexiglass discs with some holes drilled in each for charged air to pass thru.
each of the 4 sections has a metal inner and outer ring...one is cathode, one is anode
(positive and negative) there is about 1 inch gap across both sides of the diameter to prevent arcing.

between each section ( between the two discs with holes)are stainless steel mesh for a total of 3 , and all three are tied together to an exit path thru the side of the chamber.
The idea is to pulse high voltage dc on one clock cycle in all 4 chambers at the same time....and on the alternate clock cycle pull out some electrons as the air moves past or across the stainless steel mesh.
The end result is ionized air without allowing the formation of Ozone, because the electrons have been removed from the chamber into an external resistor.

my question is this:
Since there has to be a path to battery positive for these electrons to be pulled out, the stainless steel grid should be floating without a ground, pure positive potential... and since high voltage may leak across from the HV zones due to static charges, the switch required for this to alternate must be able to open and close on alternate cycles without a ground reference.
The mosfets i have looked at require a path to ground for the gate to open pnp npn ???
im looking for a high speed switch that truly duplicates a rotary drum with graphite brushes
or a mechanical coil relay that doesnt mix the switched circuit with the control circuit, problem is that mechanical switching cant go at 100 khz !

Any ideas out there?
