Re: [TCML] Rectifying methods

Hello,
please explain, why should common rectifying methods be insufficient??? Use 
a nice 6 or 12 pulse rectifier, there are no problems with this.
Maybe you should start with a "little" smaller coil to collect some 
experiences and then go step by step forward to the 20kW level ;)

Best Regards
Stefan

First of all, please show indulgence to my writing, as english is not spoken 
as a primary language.

Hello fellow coilers!

Years ago, I began constructing my very last tesla coil, a magnifier set to 
do nothing but entertain and educate the students in my hometown. I didn't 
have time to make it pretty, as I only had 6 months until dealine. However, 
it was completed and operational. Set to operate at 20kW single phase 
current, capable of 80kW, it was to be the most powerful tesla coil in this 
part of the world. As the day of the show arrived, it became clear that 
there was nowhere to plug it in, and the show was cancelled. Ever since I 
have failed with everything, education, jobs et.c. Now is the time to finish 
it.

I have decided to convert it into a DC powered coil, with the advantage of 
using polyphase current through a rectifier, but at these high power levels, 
common rectifying methods are insufficient.
I have primarily been considering mercury arc valves and electromechanical 
converters, but none seem apt in this application. I need to know if there 
are anyone out there who knows how to rectify my current, or have done it in 
the past.

I am eager to complete this monster and more than grateful to all kinds of 
suggestions regarding to the completion.
