Re: [TCML] BRISG Coil

Brisg means BRIck SisG tesla coil.
It semed like the obvious thing to do, having worked with OLTC coils 
when the SISG came along.
A BRISG has a big power IGBT, I used a CM600, which is insanely 
overdriven, pulsing up to 4500amps.
It is a tesla coil taken to the other extreme: low voltage, high tank 
capacitance, low tank inductance, solid state "spark gap".
I seem to be only person on earth liking them, -they are not efficient- 
but they have one good feature, putting them above the DRSSTC`s: They 
don`t blow up too often for no apparent reason.
The Brisg was superseded in short order, by the T-BRISG, my ticket to 
fame, or so I thought.
But, frankly, nobody seem to care.
I am still the only guy on earth having a triggered SISG and BRISG, even 
though it allows me the luxury of controlled breakrates and pure DC 
resonant charging.

I am sorry about the confusion caused by the title of that video, I have 
edited it.
What you see is simply the only coil of it`s kind, making the longest 
spark it is capable of.

Cheers, Finn Hammer

I came up with an old, archived TCML article that referred me to drsstc.com and the 'Piranha' series of Tesla Coils (not sure if it belongs to anybody on-list). I also found a video on youtube that stated that the BRISG coil took the world-record for coil dimensions vs. streamer-length.
