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
 

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?

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.

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

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!

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...

i use TC4423 IC, that's 2 inverting driver

i think he mean UCC27423 and not 27243 yeah,

hey Hydron!
the damped sine wave is at the outpout of the GDT. i dont checked the output of the fullbridge of SKM300GB.

Hey all, i just post an update, the pictures talk about them lol (debugging)
after soldered all, i made first test with function generator and oscilloscope
at the first test, the driver worked but at CW, I didn't know where it came from. after a small reflexion,
I thought of a pulling resistance to the ground which was missing, and it was the case looool!
in the pictures, my oscilloscope show directly the signal with a IGBT connected to the GDT, (here is a SKM bricks) with a gate resistor and just a 30v diode TVS.
i just have a priblem, i have a damped sine wave after each cycles, with 800mv peak... is it dangerous? i dont have it if i test the GDT imput of the driver..
so  i have it with the GDT output too.. is a really problem?

the feedback works well if the peak voltage of of the CT simulated to my function generator  is 3v minimum, ! if the voltage down, i ear a BRRRRBRBRB due to the instable signal.

pictures (damped sinewave is the picture when i measure it with curcors)


+also, the IC who driving the feedback is not a LT1016, TL3116 or MAX913, this is a AN8561ANZ, it works verry well!

I hope so too  .
besides yesterday I did a bizzare test by testing my CT connected to the primary LC circuit, I noticed something weird but I think it's due to the inductance generated by the CT, I have a frequency of 40khz when the output of the CT is not short-circuited by a resistance (resistance load for example) but as soon as I add a resistance at the output, already I have a more stable start of oscillation, but the frequency that give my CT up to 50khz ??
an idea? would it be the CT which adds an inductance which causes it to lower my frequency of the LC circuit by 10khz? and in fact I have a frequency of 50khz at the base?
