Building an Ion Generator With 17kHz Square Wave and Selectable Schumann Modulation Frequencies

Hey guys,



So after typing out 20 paragraphs in the question box and accidentally hitting the back button on my phone I have decided to keep this short.



I recently build an ion generator using a 120v primary to 400v secondary transformer connected to a cockcroft Walton half wave voltage multiplier.


It worked as planned but now I want to expand on an idea but have hit a road block held by in place by my lack of knowledge.



I'm looking to create an ion generator that  has a square wave carrier frequency of around 17khz at roughly 15kv with a selectable modulation frequency from the Schumann frequencys. 7.83, 14.1, 20.3, 27.3, 33.8.



How should I go about building this?


I'm looking only for guidance, then Google and logic will fill in the rest.


Thankyou for any help.

Hi Sean-A Cockroft-Walton multiplier uses capacitors that will make it too slow for the modulation frequencies you want.  When you say you  want a square wave- will spikes (narrow pulses) work instead? the reason I ask is that I am thinking a flyback transformer might be your best option.  Yo u could create the desired voltage directly, but it won't look anything like a square wave.Back to the Cockroft-Walton approach- If you switched the input on and off at the Schumann frequencies the output would go up and down as desired, but the rise and fall times will be slow- maybe resembling a sine wave more than a square wave.
