Hi I’m new here,

I want to build a DRSSTC for my state-certified technician final project.
I have from now on roundabout 38 weeks.
I’ve already started.

In the past I've already tried to build a DRSSTC. I got about 10cm arc from this coil:

Primary: 5 Turns 6mm²
Secondary:
110mm Diameter
370mm length
0,1mm enameled copper wire diameter (I think this is far to low)
100x280mm topload
72kHz resonant secondary resonant frequency
fixed coupling

I think it's better when I make a complete new coil.
Is this coil good?
* final.txt


I already built:
H-Bridge
Interrupter (Steve Ward)
Control circuit
Gate driver (I don’t use GDT)
Galvanic isolated power supplies for the gate driver

I’ve tested all and it works as it should. (At least I think so)
I don't have tested the feedbackfunktion I just used my funtiongenerator.

I made some H-Bridge tests with a 75W Alight bulb.

Voltage at bulb:


When the interrupter stops the H-Bridge the last falling edge is not straight, it’s more like an e-function.
I don't have a picture of this because I killed yesterday one of my IGBTs....
I Switched the 5V off while the H-Bridge was oscillating.
Both IGBT switched on I think, because of a wrong signal and the short-circuit current killed them -.-
So I made this highly professional paint picture:


Is this curve ok?? or really bad??? Idk...

Which ferrite core is good for the feedback is this one here ok (I have some of them here from my first coil):

I've added the circuit diagram
I uploaded some pics as a zip file to my dropbox (can't attach them here cause they are to big):
