Re: [TCML] Single MOT Tesla Coil Power Supply

[fleps <fleps@xxxxxxxxxxxxxxx>]

Hi Paul

seems to me you've just exactly described Mr Steve Conner's Tesla-2, 
which runs off a power supply built from one MOT and some sundry 
voltage-multiplying gubbins.  The output of the voltage multiplier is 
dc, so there's some additional stuff (like an asynch rotary spark gap, 
charging inductor and de-Qing diode) required to make it go.

anyway, he's kindly documented Tesla-2 at

http://scopeboy.com/tesla/tc2schem.html


and (carefully following this design) I built a very similar coil that 
I've written a bit about at

http://hot-streamer.com/drilling/dccoil.html

with some photos, and everything.


I think the coil works well, but all-up it was more complicated to build 
than, say, a more straightforward design based around an NST might have 
been.  Although possibly my soldering-ineptitude and general lack of 
handiness were at least partly to blame for this.


good luck anyway

Does anyone know how to up the voltage to a reasonable level for a spark gap to work efficiently; a schematic for this would be helpfull? I was thinking about a multiplier circuit, but I am unsure of how that works in a Tesla coil and also if I use a multiplier, does this effect the value of the required tank capacitor?
