Hi all, I setup all my DRSSTC Stuff here, and I get some results but not good.
I have try two Bridge Setups: - First - Second
I dont know what bridge schematic is correct for H-Bridge but I get the same result of the two ones. My CT is 1:25 Turns, and I running the GDT Driver that Steve Ward used on SSTC-2 (Full Bridge)
The driver is working fine with IGBT's, I runned a flyback and I get some 5cm sparks with 55V
But when I put TC on the schematic to run, it only get a 1cm spark to air (without a topload, with a topload I get nothing). Any Ideas?
My Full Circuit:
* C1 is not 1nF is 100nF (Changed Schematic) My Secondary Coil: (fres 180kHz~ - 64cm x 4'', wire 30AWG)

Nice work, however I'm a bit learly as to wether this is a DR or just a CW SSTC, considering, are you making your Primary resonate or just your secondary, and also your streamers look like cw mode which doesn't work too well for DrSSTC's.

I made a DR, my primary and secondary is ressoanting. For that sparks its pulling 10A :P
The sparks are at that form because the frequency of interrupter are too high (8kHz)
I only have one thing that is wrong, I need to use both antenna and CT to have a good output, if I use only antenna or only CT it doesnt work. Someone have any idea?
