Re: [TCML] BRISG Coil

Finn,

I  commend you on your innovative achievements.  The world does care,
but the economy is bad, and folks are distracted perhaps.

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The Brisg was superseded in short order, by the T-BRISG, my ticket to 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 capabl
e of. 
 
Cheers, Finn Hammer
