The PLL should be operating in blocking oscillator mode on the current peak in the series resonance.
So when there is maximum current on positive half-cycle the PLL will switch off MOSFET and flip to another half. Then the PLL should do same with on the peak of current in the negative half-cycle.
In this way it will chop low frequency square wave duty cycle to the best matching length and will make frequency shift to the best matching resonant frequency of the series resonance.
Then the signal on the PLL flip-flop time goes to the Tesla coil driver which will fire up signal to the Tesla coil.
There is an issue as well - due changing resonant frequency on the PLL the Tesla coil driver have to change its frequency to the resonant harmonic. This make manual tuning hard to achieve due changing conditions and instability of system operation. So to solve that the both frequency generators have to be synchronized. akula tried 2 PLL but that appeared to be "mission impossible" to get proper operation. My idea is from different approach - by applying frequency multiplier instead of manual frequency generator for the Tesla coil this problem go away instantly due locking of 2 frequencies on resonant harmonics all the time.

Here is Ruslan's video about mode of operation: https://youtu.be/NHpUE6oqt7k?t=9m27s

Interesting idea even complicated for me. About the second pll, i really don't find any usefulness. High frequency resonant point doesn't seem to change over the time, not even by different loads. By adding loads i have noticed only HF amplitude value changes but not frequency. Perhaps someone else will also share his findings on this to compare.

The DC-DC converter transformer details which was missing in Olegs schematics: I made 24+24T primary on small transformer with 1mm diameter magnet wire and the secondary was around 0.25mm for target voltage of about 130V. It gets up to 145V DC in in open end and drops to 87V with 15W 220V microwave bulb.
Just for comparing with your results: Out of my 28T yoke secondary i extract 270V dc. When i connected there a 42W 220V bulb, it went down to 62V. I will try today with enough fear ;D, to connect over there my Tesla coil.

Nice idea Verpies, thanks. (Even i feel that by tracking just amplitude would be easier and the same effectiveness)
Not really, because many amplitude peaks exist.  See this video.

Sometimes i find John'sK1 idea with arduino a very good choice for doing all of these. (Tracking-calculating-correcting freq.) What is your opinion for this? Normally it would be just a matter of simple programming.
If the interrupt latency and ADC/DAC/PWM quantization errors do not present a problem at kHz frequencies.

I avoid these MCU solutions for other users because programming presents a significant entry barrier.
I find that programming discrete logic "with jumpers" is much easier for them, especially that analog sections need to be built and soldered anyway.

hi everyone,

I have spent few days during available time to solder all the nanosecond generator (Oleg + Sergey) components onto the existing 1 i/c:UC3825N PWM breadboard.

This time i try to use all smd resistors (1206) and smd ceramic capacitors underneath on the track side to save space and reduce design headache.

This time i notice there is improvement in the nanosecond generator waveform taken across 1.2KV Silicon Carbide Mosfet Source and Gate.

After soldering low ESR tantalum capacitor 4.7uf 50volts directly under the 8pin IXDI614 I/C which was soldered directly on board to minimize any stray inductance that may exist.

Output of Mosfet driver i used a 2watt 1% thick film Smd resistor connected in parallel with 1n5818 diode at the top side.

I have achieved a flat top waveform at under 80 nanosecond for the first time.

But i will stick with around 78ns to 80ns for the mosfet used in nanosecond generator circuit.

The only component 470pf Mylar Polyester soldered underneath board because ceramic capacitor don't seems to function properly at 1.7Mhz.Mylar capacitor will be replaced with Mica for stability.
---------------------------------------------------------------------------
I will create a video demo to show how i use a 1xLi-ion battery 18650 which is boosted to around 22volts to act as temporary isolated power supply.

PWM circuit  merely does alternate switching for the 2 Mosfets which can be connected to 24volts all the way to around 300DC.Similar for nanosecond generator Mosfet which will be connected to HV DC supply around 200VDC.

Voltage boost circuit will be replaced by more advance Buck/boost circuit which maintain same voltage around 22volts using same i/c XL6009 if i am using higher voltage eg:24volts to 30volts.

---------------------------------------------------------

Hi.all

magpwr
pretty good
I know well how much time it consumes himself something to start ,with pleasure watch how your system works
I have a request"bought a controller": SG3525-LM358-Inverter-Driver-Board-Pre-post-Circuit-Drive-Full-Protection-Board
and I can not run it I do not know whether there must be some signal na Pin 6, 7 the scheme looks like that there is U1 PC817
and my question is whether it can be overcome?
-I removed R7 and still do not have oscillations?
or anything you can advise me
What triggers this arrangement?

hi Tomtech29,

I am not familiar with the circuit shown unless you got a schematic at the driver side.

Since i have worked with 3525 few years ago as my 1st PWM i/c .I think it's got 450mA output compared to lousy TL494 at mere 250mA.

Maybe you want to try to remove i/c and connect it to a proto board and do a test.

I have attached a hand drawn version of the 3525 done few years back. :D

Pin 14 and pin 11 is the output.


Not forgetting pin 1 and pin 9 is connected together.


But it looks the the circuit is rather obsolete since it's still using transistor handle switching.

Make it simple if you connect output of 3525 to TC4427(Safety max 17volts) or better IX4427 or even better IXDN604.All these are Dual output 1 i/c mosfet driver.

Thank you for your answer
another scheme on a universal PCB board work done but do not know how to run the system.
 This scheme is as if he wanted to plug in
what was I missing?

Hi Void, thanks for sharing your experience. :)
Smaller hissing but exists, happens to me even with no active HV. When also HV comes into play, things get worst. I remember, in some cases with my previous setup, things got better when i was connecting earth ground to my metal pots together with the (-) of the battery.

Hi Jeg. Yes, the HV makes everything a little more challenging. I tried using grounding at different
points, including grounding the metal pot bodies. In some cases earth grounding the pot bodies
acted the same as me touching the pot with my finger. It caused the bulb to get brighter at certain
frequencies, but the PWM would draw more current. I have been doing a lot of different tests in the
last several weeks with the goal of looking for what might possibly cause an OU effect. I have a few
ideas on this, and I haven't ruled out something like NMR or spin waves either. The particular testing I described
in my previous comment was deliberately done at low power level to see if I could notice anything out
of the ordinary with the spark gap and driving with PWM pulses at low power levels. Nothing unusual was noticed.
I have various other tests planned as well, including driving the coils at a much higher current level as was done in Akula's setup.
I am taking it step by step. I will post a comment if I come across anything interesting. :)

P.S.   I am currently leaning towards something like spin waves being the most likely explanation, if the OU effect is real.
I have tests planned to pursue this line of thinking further.

Hi Void. It looks like we are on the same wave :)  I am also in the process of learning. I have made three identical small Tesla coils and study the effects of transmitter Vs receiver.
Did you start to build special antenna yet? ;) (ferrite rods in circle around the former and some turns of wire)  -Some document I found interesting below ;)

Itsu- very nice finding - I have already ordered some stuff from that page:)  Just couldn't resist :)

Hi John.k1. The spin wave theory is actually something different from scalar/longitudinal waves theory, but
scalar waves is another possibility I am considering. Thanks for the document from Meyl. I am familiar with
his stuff. The problem for me with professor Meyl, is he didn't seem to put much importance on the measurement
procedure when he claimed that the two tesla coil setup could produce OU. That raises some doubts about
his claims about OU in my mind, as we all know that the measurement procedure in regards to claims of OU is often
where OU claims fall apart. :) Something interesting that Meyl stated is that he said that there were two resonant
frequencies in the pancake tesla coils that Meyl could drive the coils at, but only one of the resonant frequencies
gave the effects he was interested in. If I remember right, I think it was the higher resonant frequency that
he said to use to get the right effect. 

I personally think for all the devices Akula has shown, that it seems something along the lines of NMR or spin waves
or a similar type of effect would best fit as a potential explanation.

Spin waves are described in Wikipedia as:
"propagating disturbances in the ordering of magnetic materials."
An engineer named George Bugh has informally researched spin waves and has put forth the hypothesis that spin waves may account
for the over unity effect seen in certain claimed OU generators. It seems to possibly fit as an explanation for how Akula can supposedly
get an OU effect out of the various device configurations he has shown. The general idea is that magnetically pulsing certain types
of materials may release excess energy under the right conditions. Not just any type of ferrite or other material may work however.
You may have to find just the right type of ferrite or iron, etc.

George Bugh has some videos on spin waves here, in case anyone is interested:
https://www.youtube.com/user/narivasant/videos

Keep us posted if you find anything interesting with your tesla coil experiments. :)

Hi void- Is the spin wave and spin field the same think?  I guess you are aware of the experiment by using special antenna :  http://www.zen22142.zen.co.uk/Media/fsi.htm

It is next think I want to try. I have many ferrite rods ready, just not sure what to do with all that  :). The ferite should not to be thick, otherwise you will get some sort of hysteresis. This brings me to an idea - what about to use a very skinny "painted" stripes made of black sand?

I was listening E. Dollard this week - eccentric person- but some things he talks about are fascinating. What attracted my attention was the information about the modulation of the statick HV field- and you will end up with very high magnetic field- Something not far to what Ruslan says, what Romanov says etc..

To show you the cycling effect when i loopback the 24V PS to the input 24V battery i made the below video.

Both the PS as the Battery have a big diode to prevent any of the 2 to charge the other.

I think it must be some interference / difference between the 2 DC voltage levels which is causing this cycling.
Probing the 24V from the battery (after the diode) does not show anything abnormal other then the some cyclic pulses, see screenshot.


I also show you on a spectrum analyzer the spectrum generated by the Yoke/TL494 system when in resonance and when not.
It seems that it generates a base signal around 14.3MHz  :o and when in resonance (or just below or above it) a lot of HF noise up till 50MHz  :(
Normally you would not be able to hear that, but i think it is the source of the hissing sound (via Low Frequency Detection) we hear coming from the TL494/yoke.

I think the cycling is due to the lack of sufficient amperage for the power supply to drive much of anything.  So once it's output voltage comes up, it immediately tries to take the load, dies and the battery resumes powering the system.  If you connected the power supply output to a pair of 12 volt bulbs connected in series, I'm pretty sure you would see the same thing.


Video here: https://www.youtube.com/watch?v=Z4UYBrmh_OA

Now that is interesting.  I would not have guessed there would be so much high frequency radiation going on.  It appears pretty strong too.  Very surprising.

Hi itsu,

I got some quick questions:
Why you are using separate battery for +12V power input to the electronics and not voltage stabilizer as in Oleg's schematic? This is making another loop for the kicks coming from the coil back over that battery...
Can you show what is the voltage directly out of looped power supply without diodes and on the battery side?
The fluctuations seems are due voltage difference between output of the battery and the looped power supply.

Cheers!
