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.
