So this coil is only a half bridge? I guess you must be using ISOTOPs. I use the IXYS 60N60s in a full bridge on my coil.
38" is quite impressive. I suppose you had the OCD set for 600A? I have yet to break 390A on my coil.
What operating frequency are you running at? ~170kHz? On my coil I have the coil tuned for about 135kHz.

Excellent! I use Steve's latest driver too. I'm about to tear down my enclosure and replace it with a nice black acrylic one :) By the way, now long are the sparks in this photo? Looks like at least 30+ inches.

Awesome performance!

No...its a fullbridge of HGT1N40N60A4D
mini blocks...i only have four spare, so when they blow, i'll have to get different ones as these IGBT's are hard to get now.
Yes i think i had the OCD set to about 600amps at the time, thats not nearly as impressive as your little coil outputing some 30+ inch sparks at only less than 400 amp primary current!
Yes...my operating frequency is about 200Khz

I think the spark length was about 38 inches. The secondary coil is 12x4 inches.
I had just finished making this coil on the previous night just in time for the Nottingham Teslathon, so i never really experimented with tuning.
I awaited for Richie Burnet to view it working as he has requested, only to find
that after about 30 seconds it blew half my bridge!...doh!.....that must have impressed him!...lol

Cheers Phil,
I have now demolished this base unit and replaced it with Steve Wards latest
universal driver/controller, everything else remains the same.
i'm nearley finished and just about to fire it up for tests.
