Do you have guidelines for applying this SISG.  For example, is this a
direct replacement for the static gap in my 12kV, 60 ma coil?  Would it
then be necessary to apply 12000/900 , or at least 14 SISG units in
series.  I must be missing something, cause that sounds real expensive.

Thanks,

FJA

Hi,

The SIDAC/IGBT Spark Gap "SISG" was BORN today ;-))

Here is the first picture:

http://hot-streamer.com/temp/SISG-Born.gif

The inductor was 634nH, thus the fast ring down, (like a dead short
jumper wire) ;-))  260kHz with 600nF of capacitance firing at 900V.

"800 Amps" at "0.05 ohms" effective resistance ;-))  In most cases,
even the SUPER TO-247 will not need a heat sink ;-))  Mark at 460 BPS
will need little ones ;-))

Hehehe!! just scope pictures, but no "sparks"...  But us "scientists"
now that the "sparks are trivial now" :o))))

The modules work in series just fine and a single module can be "way
overloaded" with NO apparent damage!!  I drove 700 amps through the
old one many times and it lived just fine...
