Tesla primary coil rectification

[the_big_m_in_ok]

Hi to all

After the spark gap in a tesla coil arrangement, i take some bursts at the BPS frequency. Those bursts consists of the oscillation frequency between discharge cap and primary coil which is around 300KHz. In a try to "play" with this signal, i am thinking of rectifying it. The voltage is around 4KV but current is unknown.

My question refers to which kind of diodes may i use so to rectify it without problems. I look for something cheap and capable of handling all these peak currents.

Time's short on this computer.   But, my question is...
Do you have a schematic of your own, or else, an Internet schematic of this circuit you can upload?
Otherwise, a couple of strings of diodes in opposite directions to a smoothing capacitor in parallel and then to a battery bank is the way I would go about it.

I saw two ways to capture that recently... getting the full potential without extremely complex diodes. ( they recommend silicon tubing around said diodes filled with oil)


Add another spark gap from the end of the high voltage to a cap.  This will take off the very top of the voltage, and allow the resonance to rebuild in the circuit.

The other way, which does't get as much is an avermenko plug , or even a single diode to another coil using that coil as a pickup; the diode isolates it from the coil a bit ..

@d3x0r
Your response got me thinking:   There was a patent application I finally saw reference to on GOOGLE  IMAGES...

This is a dresription of the source of my info:
      A Practical Guide to Free-Energy Devices,   Chapt. 11
(scroll down the page until you get to the reference to...
       Paulo and Alexandra Correa and their Patent Application,   2006/0,082,334

(It does show a double set ofreversed polarity diodes attached to, and leaving, a Tesla coil torus.    The output can be capacitor-filtered and tied to a bank of batteries, of course.)

Note:
This computer is borrowed and the software is very 'third-party-originated' to where the Internet function is barely useful.   It is free for me to use as long as my butt and thighs can stand sitting here in this chair, so I guess I shouldn't complain too much, I suppose.
       I can only give you the description above to go by and you can GOOGLize it if you like.

Good thinking, though, d3x0r.   This might be something to think about later when I have more time.

Thanks for the answers guys

I didn;t have the time to watch the videos but i'll do it tonight and i'll come back on this.

My main purpose is to rectify the main signal-oscillation of lets say about 400KHz, so to be able to extract the BPS frequency and use it for power supply. I am thinking to handle this the same way as a simple AM receiver.

I am not going to comment on the topic per say but I would just like to get this out there as I have had some real success with this setup looks like the two coils on the top are somehow being influenced by the dialectric field of the topload on the first secondary.
This setup really increases the magnification and makes the hair stand up on anyone in the vicinity.
Hope this helps someone out there.
