Jeg,


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  ;D

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)

Looks really good what you have so far Itsu.

You may want to try putting a controlled load on the output of the 24 volt power supply just to get a feel for the efficiency of your system.  I know my power supply will begin to oscillate at about one or two Hertz when power demand begins to exceed power input--I'm sure this has to do with the size of caps inside the power supply.  It's very possible with the loss-less clamps you don't need much to hit unity.  If you can add the proper signal mixing...

A looper might be just around the corner.   :-X

remember the 220vac is the RMS voltage not the P-P voltage. RMS is roughly 70% of the P-P and the 220 is only 1/2 of the P-P

since the 220V is rms voltage, which comes to +-312V peak (220/0.707), so peak to peak is 624V

Jeg,
Well, 800V (pp i guess) is much better then what you had earlier....
If you consider that my previous setup was giving me something about 350Vpk-pk, then 800V pk-pk seems a good level.

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.

Thanks for your opinion and also for the video. Your lossless clamp seems so ideal for this job!!!
I'll try to do the same experiment today with my +24V psu, and i'll make a video.

I wonder with just your inductor line in place (without using the 28T), what is the voltage levels that you reach across your output capacitor when your load is this 40W bulb?

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.

Dog and Starcruiser,  thanks,

yes i could try to load the 24V PS to see what effect that has on the 24V battery input.
 


Jeg,

i will measure the voltage level across the output cap with 40W bulb installed and the 28 turn secondary disconnected later tonight.

The hissing sound is very familiar, it happened with all my yoke setups, i call it the chaotic mode as the scope shows chaotic signals (MHz range).
I had it very strong with this same setup, but traced it down to a faulty soldering (using leadfree solder  :( ) of one of the TL494 output to ground resistors.
I had 1K Ohm resistors there (i see you have 600 and/or 800 Ohm), but verpies adviced to load it more to 100 or even 68 Ohm for better stability.
Be aware that with 15V on the TL494 at 100 Ohm they can get rather warm, so use 2W resistors or more.

Anyway that bad case of hissing went away, but still i have it now and then, especially when approaching resonance (short bursts only) or around the lower TL494 range = 11KHz.

Other things i did before i found the bad soldering was:
# use solidly decoupled supply voltage for the TL494 and drivers
# use short leads between TL494 and driver.
# use lower TL494 output to ground resistors, see data sheet.
# removed the metal clamps holding the yokes halfs together
# make sure the 3 turn winding is NOT directly over one of the Yoke splits (but 90° apart).
# isolate the yoke halfs with paper or in my case electrical tape.

Anyway, the hissing sound in the yoke and the movement of the current needles of my batteries input still happens sometime.

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.

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.

Jeg,

the IRFP460 can handle 500V drain / source voltage, so besides some possible spikes it should be OK.
I did use 130V drain / source voltage, but with a very low 200ns driving pulse.   
Only protection was an 18V TVS across gate / source (and the 1K resistor from gate to source and the 4.7 Ohm source/sink resistor per Olegs blue box).

Only problem (with the Kacher) was that my DECT telephone started ringing when firing up, sparks would fly from every bare metal, my laptop computer crashed, a current probe got fried and one part of a dual PS went up in smoke, thats all  ::)

 
My inductor coil is 2 layers and about 11m long, so less inductance.

Geo :)
Thanks for sharing your experience. My new push pull uses ground plane. Its operation has been improved enough only by this addition. Insulated yoke halfs as Itsu describes, and a plastic screwdriver ;D

Geo, in addition the most of the chaotic mode as you call it has disappeared due to the fact that akula's snubber has been corrected and so there is not ringing across the yoke. Those random frequency spikes at drain is the main reason behind 'chaotic mode'. See at previous pages when we were discussing about this if you would also like to improve it.

Thanks Itsu. I knew about your inductor and that is the why I wrote my inductor's specs so to avoid confusion.

Sorry to hear about your loss. Before some days I also lost my DDS 12Mhz signal generator. It was new and the second fg that I fry. I already ordered a new one again from eBay at 24Mhz.
Now that you mentioned this, I'll think it more before procceding. I can't afford more damages.

Itsu,
There is one thing to do in the series resonance setup - let that power supply support series resonance back on input then see how much power the circuit will take from the battery. This should be interesting to see.

Cheers!

That is a fascinating mode of operation.
Apparently there is some feedback from the output to the control pins of the TL494 but this feedback should not result in a chaotic mode without the "Kacher" - it should be a steady squeal like the one that happens with a speaker and microphone feeding back into each other.
