Re: [TCML] Rectifying a Tesla coil (was Franklins bells)

[<pterren@xxxxxxxxxxxx>]

I don't know anyone who has rectified a Tesla coil to produce pure DC.
A string of IN4007's would be unlikely to do it as their recovery time means 
they are not much good over 20kHz, let alone 2-400kHz for a small coil.
High speed diodes would work but you would need very many and they might not 
be avalanche rated.
I tried a string of points/concave electrodes without much success.
Has anyone else had proper success?

You need DC for this, less than 10 kV, and insignificant power. I have
