Dear All.

I spent another fruitless evening looking for anomalies, nothing to report.

If I have correctly read the schematic, the Mosfet switches in series with the transformer and the load is fed after the primary winding?? In other words current is drawn through L1 to light the LED's ?? So could this be why I am not seeing anything unusual ?? The simple reason being I am not pulling enough current through L1 to create a strong magnetic field ??

For the EE's, can I use my PWM connected as in  figure 4 from the attached PDF ??   To create the condition I have explained above ??

Thought or comments gratefully received.

Cheers Grum.
Do like in this picture and you, I think, have bigest chance to make this divice). This schematic is from author.
He say, that first wound primary coil of 15 turns, turn to turn wound, then piesce of paper and wound secondary coil 45 turns, also turn to turn. Coils wound like show in schematic in oposite directions.
Also not wery clearly say, but something like this, that after primary coil is short turn of ecran (one turn of tape of specific metal, maybe cuper is good) and after secondary coil is short turn of ecran. So wound primary, then tape of paper, then ecran short, then secondary, then ecran short. Load 5-20 W LED 12 V.

@Grumage, MenofFather and others: Keep up the good work, we will get there somewhen, im sure. I cant help much here atm, as im still busy with 2-3 other devices and wanted to wait for RMcybernetics PCB before i start.
Men of Father, well good luck!!!!! But u sure that schematic came directly from akula? If u shouldnt be succesful like this, maybe u can try again with a ground(minus) connection on the other side of R20. If u are in contact with akula, maybe u can ask him about this connection too?
Also try to confirm the schematic he sends u is really the one u received, perhaps he can have a quick look here.

All the best and kind regards!

NO. Schematic not from akula, but from man, who make this free energy divice. Akula not answering to questions, he only to one my question answer. And help me only, then I work on it one divice...

Good day Grum:

Basically when designing and SMPS one must take into consideration Switching Frequency, operating Flux Density, resulting core loss and desired operating temperature.  Also depending on the topology of the device, full bridge, push-pull, forward, buck , boost, cuk, sepic, etc; you must know before hand which quadrant(s) of the B/H curve you plan to operate within. ..

 Without sounding like a broken record repeating the Zen interelatedness of the various factors which are all critically related,  I want to mention just a few facts that affect the design of the SMPS XFMR.  I think this is useful for review considering that the design of SMPS XFRMRs is just as much an art as it is a science.

It is without doubt the most difficult piece of an SMPS to be designed.....

 DC conduction losses and AC switching losses:


 Transformer losses can be divided into:
1:  core loss — the energy used in magnetizing the core, and:
2:  conduction loss associated with passing current through the windings of the transformer (I2R losses).   Meaning that wire size, path length and winding density all have a role to play.

The inductor core loss is an AC loss that is a function of switching frequency. Core losses are due mainly to magnetic hysteresis loss, which can be imagined as the friction generated as the Magnetic field induced by the inductor snaps past the crystalline lattice of the inductor matrix (material composing the inductor).   In a high frequency SMPS, the core material may be powdered iron or ferrite. In general, powdered iron cores saturate softly but have high core loss, while ferrite material saturates more sharply but has less core loss.

Unfortunately, you also have to deal with Conduction and Switching losses generated by the Switch (MOSFET) also:

When you double the switching frequency in a design, you halve your flux density for a given number of turns in the transformer.

So:

Smaller cores can more easily tolerate a higher peak flux density at higher switching frequencies than larger cores. Why? Because core loss is proportional to volume but cooling is proportional to the core’s radiating surface area.

I have seen more than one Russian designed 'eternal light device' that the developer has complained of 'MOSFET overheating problems'.

Please see link from Wesley;        http://www.youtube.com/watch?v=eUxFuW3JYdY

Anyhow, I see a trend here on these devices in general:   There is some type of anomaly involving the functioning of the transformer to invoke an excess of energy production:  This directly affects the functioning of the MOSFETs, maybe throwing them into Avalanche mode or at any rate affecting the switching behavior as to illicit an overheating condition.

I have attached more detailed information on SMPS core selection and magnetic information FYI.

Well, I wish you the best of luck with this.

take care, peace

 Hi guys,

 
I have been monitoring this thread from start.

 
Here is what I see:

 
The 'Akula0083 circuit' you are trying to duplicate is essentially a simple device which
(for simplicity), can be divided into two (2) sections:

 
a.  Control (“exciter”)
b.  “Free energy”

 
I comment mainly on the control section which you have thoroughly messed up!
Admit it or not, most of you have contributed to this.

 
I am particularly critical of some of the 'technical' comments made!
They are WAY OFF!

 
OK.
The control section is based on the TL494 PWM IC which has been around for over 30 years.
It became an industry standard, so to speak.
In the past, most computer SMPS used this IC.
It is well understood and works well.

 
If you care to watch (and pay attention!) to the video where Akula explains all three (3) versions of his MOSFET drivers, you would not be confused and would stop 'butchering' the circuit!

 
For example, arguments are still raging about that Ground wire connection to pin 16 of  TL494.
Know this:
If you remove that connection (like I have seen in some diagrams in this thread), you will also lose the Ground connection to the indicator LED HL11 AND the Ground connection to voltage divider R9-R11-R10 which will result in error amplifier A1+ (pin 1) will be at the supply voltage (+12V) potential trough R9 and part of R11 (pot)!

 
This has already been pointed out by one poster ('lost_bro' on page 6) and yet, even as I write this, yet another diagram appeared (“Akmodedit.png”) where that Ground connection is MISSING!
This diagram has been REPEATEDLY posted!

 
In other words:
By removing that Ground connection in the diagram, you DISABLE not only the indicator LED but also DISABLE BOTH error amplifiers, A1 & A2!

 
If you pay proper attention to the details in this video:

 
http://www.youtube.com/watch feature=player_embedded&v=EwCS15pRtH0&list=PLC7684829E98CAD74

 
you will see that the disputed Ground link (connection) is PRESENT in all 3 versions of the diagram.
No, you don't even have to understand the language!

 
By the way, the author announced a few days ago that English subtitles are coming soon!

 
Then there is one other point which everyone have missed, including Akula it seems!

 
Irrespective of which (of the 3) MOSFET drivers you use, there is only ONE MOSFET in this device and the drive is single-ended.
Period.

 
Yet, the output logic control (pin13) is tied to pin 14 which is the reference voltage.  (+5V, ±5%)
Therefore, the output stage is operating in push-pull mode.
(Only one poster commented on this, in RED, written over the diagram.)

 
Sure, it still works this way BUT the output frequency is only HALF the oscillator frequency.

 
If pin 13 was connected to Ground (0V), the output would operate in the single-ended mode which gives the option to parallel the two output transistors, thus gaining significant current drive to the MOSFET, either directly or through the complementary NPN/PNP driver, or through the dedicated Mosfet driver IC (IXDD609 or similar).

 
Lowest rise/fall times are achieved with dedicated Mosfet drivers (they are MOSFET based).
However, unless I need super fast switching, I prefer the complementary npn/pnp driver since I found that the MOSFET drivers are too “touchy” for experimental work (meaning they are too easy to blow up!).

 
To those who intend to try to duplicate this circuit, my advice is:
Make sure the control section works properly before attempting to experiment with the free energy section (which the transformer is part of).

 
Also, don't fall for all that nonsense (yes, nonsense!) about input/output power measurements as some posters promote!
Why do I make such a statement?
Simple.

 
You are NOT dealing with a device with a claim of marginal OU in the order of a few percent which could perhaps be a measurement error!

 
If you want to know the input power to this device, I can give it to you right now:
The TL494 IC, running on a 15V supply has a maximum current draw of 10 mA.
(average 7.5 mA)
That translates to 150 mW (0.15 W). (maximum)
Add the 12V regulator's power consumption of approx. 96 mW (maximum) and you have a
TOTAL of 246 mW (0.246 W)

 
Now, just for the hell of it, DOUBLE it and round it to 0.5 W.

 
However, this device will produce 30 W (or more) depending on the LOAD and the transformer
you use.

 
I hope you can see the stupidity of those who blindly INSIST on input/output measurements!
Don't get me wrong.
Sure, you will be curious (as you should be!) about the output power of your device!

 
With devices like these, you may face a very different kind of problem!
Avalanche.  Yes, avalanche.
I hope you know what that is.
(It is a runaway condition which, if not controlled, can cause DESTRUCTION of great magnitude.)
Don't believe it?
Fine.  But don't complain if something blows up in your face!  (or worse)

 
Oh...'MenofFather' posted suggestions to the winding method, including SHORTED turns!

 
Guys, with all due respect, with that kind of suggestions you will never get anywhere!
Guaranteed!

 
Cheers,
Les Banki

Good evening Les:

I've read about your work with the HHO, fuel injectors and the like (PESwiki);
I've also spent about 10 years playing with/experimenting with the SM resonant HHO system.  Had some interesting results, but not like SM described.

Great to get your input on this circuit.  I have not had time to wire it together yet, but I've been following the thread everyday.
Seems plausible, but you are correct to comment that if the signal generator / logic side does NOT function, nothing will function, not even with the original correct coil that Akula used.  So many variables to deal with.   I have wound many many coils dealing with the SM system and I will be the first to tell you that XFRMR design is very tricky territory.

Best of luck to everyone.
take care, peace.

@All,

I can't understand why people still are discussing the "ground issue" of the TL494.
This issue was solved in post 1 of this thread. All you have to do is download
the file "Akula30Wattv2.rar", unzip the file and look at my circuit drawing. I did
understand when I designed the circuit that the ground was missing and included
a ground path on the PCB. It was also discussed on page 1 of this thread. I was
asked by Grumage to design a PCB. That was what I did. There is nothing wrong
with my PCB as far as I can see. It may not be the best design but it will do the
job.

Due to proposed avalanche effect the name of the thread should be changed to Drakula runaway generator.  ;D ;D

Mr. Banki scared me by saying something can blow in my face.   :-\

Pun intended.

Best,
