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...
