Well. there is something more. It was happening to me while experimenting with my old push pull board but as i see, it also happens now with my new board. Even that now i use a ground plane, when i approach my finger close to the pot that varies pwm (tl494), a strange noise like hissing appears. The same time i see the current needle at my input to fluctuate. When i take my hand over the pot, this hissing sound disappears. Have you ever noticed something like that with your board? I use the attached schema.

ps.1 It doesn't happen the same with the frequency pot. hmm. I wonder if my body's capacitance affects the capacity that pin5 sees.  (CT=10nF)

ps.2 With a plastic screwdriver there is not any hissing. With metal screwdriver or with just my bare finger, hissing appears when i am as close to the pot as 1cm.

Hi Jeg

This is exactly the same effect I witnessed on my tl494 / ir2110 board,
the moment you touch or even get very close to the Duty cycle pot or Freq pot it will hiss and strange noices.
This is where you are close to replicating what I have, You gave to tune the Duty cycle pot to  where you almost kills the
output load out of grenade. It will stay on a Chaotic Distortion when you have it right and you will see
where Only when kacher is on, there is light and all lights are equally bright depending how you tuned it all.
Makes sure the ground well connected.

Until now I have to change almost all Ic's, voltage regulator, mosfets after the accident of removing the ground.
Battery of 24V+ will be in place also instead of mains for the testing, to see the difference but I already know it would
work the same and will try to measure, because last time it was hard to measure with some meters.

Well, 800V (pp i guess) is much better then what you had earlier, i have about 570V pp across the inductor or wima caps.

The polarity does not matter, there should be / is a FWBR in that PS which will lead the positive always to the positive rail, draw it out then you will see.

Be aware that the DC voltage can go higher then 220V when using different loads, i have to load the Grenade with a 40W bulb to get around 212V DC.
If i use more load (100W), the DC voltage stays to low, if using less load it can go (too) high.

Off course, your 24V PS is different then mine, so no garanties 

I made a little video about my new loss-less clamp yoke now with the 28 turn secondary also installed, showing the both polarities ±212V DC connected to my 24V PS.

(The blue DMM does not change polarity as it was measuring the input which did not change when i turned the plug, therefor i made 2 pictures showing both polarities as input and its output, see below)

Hi Itsu

Nice results and saw your video with the lossless clamp setup,
Good High voltage only using inductor but consumes after adding load or something els. and could turn on the PSU 24V,
You should check what the 28T does when connected to the system, see what voltage comes out.

With some more careful measurements.
Inductor line is in place, without connecting yet the 28t yoke secondary. Inductor 18.75m, three layers of 25T. Voltage across cap 1.12KV pk-pk without load. With a load of 40W, voltage across capacitor 750V. The reason for these higher values is the higher inductance (3X25T). Dc voltage across the output capacitor, 180V without load, 100V with the 40W load connected. 30V with 500W load, 20V with 1KW load, and about 10V for 1.5KW.

Itsu. At the ends of 28T coil I connected a bridge and a filter, for supplying later some dc voltage to my Tesla coil stage. It outputs there 275V dc without load. Is it too much to feed with this my irfp460? I remember' that your supply was close to 130V. Did you have any protection for irfp460? Any problems?

Ps.1 Thanks for the video and the polarity info. I will first make my HV stage and then I'll try it.

Ps2. Frequency drifting in relation with coil temperature confirmed. So different load is not the only factor of detuning. Pll is a must.

Nick, i would not do that, afterall, what can you expect without a kacher or hv pulsing / disrupting device and without a ground.
