hey mads! thx for your answers all
I use 0.4mm diameter (AWG26?) for my secondary. now i have 90cm winding lenght for 160mm diameter...

Bit of a late welcome to the forum!

Nice looking build so far, I'm a fan of the solder lug style capacitors. I've used them in a few builds now and they're (the kemet ones I've used) basically bulletproof! Looking forward to see your build progress!

Hey, i post à New Update.. Singe 2 day, i try to fond aluminium/copper pipe for the topload, and Here israélienne the secondary coil.. (1100x160mm)

Last day in made the famous topload!
The secondary alone résonate at 107khz, and with the big topload, IT résonate at 58khz!
I used plumbing aluminum sheath

two or three more things and I can try it out first!

Looks nice, but you might want a breakout point. Easier on IGBTs if you add one.

The breakoutpoint is planned haha
I need to make connexions for the topload now and make this Week the first light

Hey all, I made preliminary t'est !
So when I turn up the on time, It dont up, I think that's because the power source is around 50w loool

the video with very low power test!!!
at the last message i said my primary doesnt worked, that's false (i dont explained very well lol), we can see the primary courant  signal at the scope.
i used so a transformer  40 VA of power, for 80v BUS. i think i'm verry limited with this supply because when i turn more the on time, the primary current sown quickly. but after , because the power supply dont give too much for the bridge and primary circuit.

I make some t'est yesterday.. Always with 80-100v bus. Is a good idea to make settings with a 40w transformer for the power? Lol
And for phase lead settings? Here is photo aboutissent voltage output bridge and the primary current with output of CT, as you can see, I have a lot of pics and a lot at the current signal, wtf? Are real?


A update of the omegaDR now. I have wirh 40w 10cm sparks and wirh pulsé skip 30-40cm sparks..

I'm waiting also for a 2kva variations for it. Will Be 1.2m for 2kva power?

Good progress and congratulations on first light!

The spikes on the blue current signal is switching noise and you might need to address that on the CT used to measure the current.

The spikes on the yellow is pretty good for low voltage testing, no need to worry there.

At 2kVA you will hit around 1.5 meter.

I tested à New try, with a inductor I have that!
I changer the résister burden ce nnected to the CT (5 to 600ohm) for better check at zéro crossing. I have always thèses, but I have down pk output voltage bridge!
I moyen almost peak voltage, but the peak output CT are really always Here... (We dont see Ir because thèses pk are to 800mv Max) is that dangerous to have this blue pics at output CT?

600 ohms is high for a current transformer burden resistance.  Could be fine if your CT inductance and volt-seconds are high enough.  If CT inductance isn't high enough, then the high burden resistance will introduce phase-lead into the current sense signal, making your phasing measurements inaccurate.  Volt-second rating appears to be OK at your test power levels, as there's no obvious signs of current waveform distortion due to CT core saturation.

Hey all, I want to make an update from my OmegaDR, I Have Nice picture about Nice sparks.
For simple, I made quick voltage doubler for 160v from 80v.
So, the problem was my transformer that give this voltage but with not with a high power (40w) this Is why I used just one shot, interrupteur, with normal mode the dc bus Caps voltage down quickly.. Here is the picture:

I have ans vidéo about this..

For this Week I wait a Nice variations for some test !

See ya

Hey all
À vidéo à bout the OmegaDR.
I used 1.5kva power formation this test.
I dont checked the OCDE set, this Is why I testée quickly

Light was not heating, I use SKM300GB123D :D
