Title: Chinese Oscillator and MOS FET Driver, Hardware experiment
Post by: AlienGrey on November 13, 2020, 10:37:08 PM
Getting back to Chinese oscillator FET Driver circuit.
I striped down a XT power supply and re wound one of the smaller miniature long E core
'soft' ferrox former and re tested and it produces a perfect sine wave @62.5khz

Chet it is the same thing. Chet we need some feed back from Stefan and a thread creating for me to copy
the series of instruction picks into with some sort of disclosure statement, it might be this the problem.

pinching bits of it is one thing we can do but the sauce now expect folk to pay them for it.

In that case Stefan might have another way of solving the problem

Chet 'the cores he doesn't give any info on them the bar cores are the softer type not the ceramic type
the E cores looks like the ones out of old XP power supply.

The grenade style gr coil I think i would try a pile of rings end to end about 26mm dia the wire he used was Teflon coated
stuff out side dia is about 1,5 mm for the blue wire and the white is about 2mm outside dia to fit in the spaces.

I would have thought some bright spark would have got it going by now

Hasn't any one else got or down load's any of the old vids ?

Guys, does anyone know how those machines work? It says 230V/50Hz but i feed it with alternating dc at 110KHz and seems that it works normally. What is the catch here? Are we talking about dc motors with a bridge at their input? ::)

In addition, i would like your help on the following.
We see at the china-kapa device that the 28T output of the zvs ferrite transformer, is in series with a cap and an output transformer. The input zvs inductors are of 5 turns each. So 24V/5T=4,8Volts per turn. So 28T X 4,8V equals 134V peak. My oscilloscope here shows almost 200V peak. Why is that? Is it due to accumulation of voltage cycle per cycle? And if this is true then do you think it is possible to raise voltage even more across the 28T coil without adding more turns to it? What the maximum voltage at this point depends of?

Thanks :)

Do you think you might be missing some thing ?  I think the fets are feeding a very loose coupled magnetic coupling across the ferrite core and also the cap isn't any old value it has to be tuned to match the two inductance's do that and see how far you can get. Lx = Cx the play ground swing perhaps.

Also when the guy was winding the coils I also noticed both sides of the wingdings were not equal or was it an illusion.

Hi AG
I don't understand what you mean about loose coupling. It doesn't look loose to me at all. Of course when it is in resonance, then Lx=Cx which gives rise to current. Shouldn't voltage have to follow the turns ratio thing?

About the Chineese's number of turns, there is only one turn difference between left and right coils. 50T and 49T. Not a big difference. The middle coils are of 48T each.

One other thing the jig saw is inductive shouldn't it be a restive load ?

Why to use only resistive loads and not inductive ones? It works with both kinds. But behaves better by using inductive loads. Meaning that COP is higher with inductive loads in this inverter.

Packing the PVC core with magnetite composit would be much simpler then shaping that rectangular job right?

There is really not much to this build; The coils are household wire! What kind of advantage would there be in building a ferrite core with blocks? Permeability can be controlled with particulate ratio.

Yes this is true. Only the total ohmic resistance will change. I used ferrite rings for this task.

What is your opinion on the voltage across the 28T coil? Should it give a voltage level depending on the turns ratio, or it also depends on other factors due to the in series resonance?

That shift in voltage could be caused by incorrect grounding of your oscilloscope. How is the scope grounded?

Yes it is grounded but now that you say it i will check again. My Rigol's probes are all grounded.

Ahh do you think it is because we have a zvs driver? The primaries are in a parallel tank circuit which gives rise to voltage. Perhaps that is the reason.

If you are reading voltage off the 28T coil, that coil itself needs to be independently scope grounded to get an actual measurement.

Post by: Jeg on December 05, 2020, 02:13:28 PM

Resonance must account for it.

I'll change resonant point to lower values than 110Khz, to see its reaction. If i could step up the voltage across the 28T without raising the input voltage or the turns of the secondary, i might reach the result of the Chineese in terms of performance. Across 28T i measure 400V peak to peak, but Chineese's device might be well more than this.

The capacitor tuning for high "Q" is where you get the advantage. Do you have a tuner connected to your capacitor?

Nice point!!! I just don't know how to increase the Q of the primary side when using just 5T per primary. I'll make some calcs more to see. Perhaps his ferite core is more suitable than mine's. I use just a simple yoke core.

You need a tuner cap! There's an 8000 volt .022uf capacitor in the schematic. That's the trimmer cap! You got it to ring, but any further resonant voltage rise would be a consequence of the trimmer capacitor adjustment for "Q" in micro farads.

Thanks, i'll think more about it. The other solution is to make a peak shorting across the 28T to raise its voltage as much as i can. For now i am just trying to go as per Chineese circuit. Even if there is a fat chance that the Chineese hides something in his contraption like a HV converter module. It is not possible with the given circuit to reach 200V across a 2KW induction cook like the Chineese shows.

Exactly. This is an indication that we have HV running inside his tank circuit. I can't reach a higher than 400V pk-pk. I also use an input choke to my ZVS driver. The Chineese doesn't.
Title: Re: Chinese Oscillator and MOS FET Driver, Hardware experiment
Post by: synchro1 on December 05, 2020, 02:49:17 PM
The "Gimmick" is that the designer matched a household wire coil to a resonant capacitor and tuner all in correct proportion to deliver a very high "Q"!

The high 8000 voltage rating does not prevent the trimmer from working in the lower voltage ranges; However, when tuning for "Q", these voltages develop between the capacitor plates. The trimmer is nothing like an ordinary butterfly capacitor.


The coil turns and primary capacitor are matched sufficiently to produce a basic resonance that the fine tuner capacitor can operate on. Ordinary variable capacitors will burn out too soon.

There should be a diagonal slash between the schematic lines for variable uf capacitor. Placing a fixed uf rated capacitor at that location in the circuit would be worthless! Only by fine tuning LC tank resonance in micro farads from this tiny specially designed capacitor tuner can the higher voltages be achieved!

The two horizontal small caps are in the primary side. 0,47uF each. Total c=94nF
The big one which stands vertical is the 8000V/22nF and it resonates in series with the 28T and the output trans.

The addition of a high voltage trimmer capacitor in parralell with the 8000V capacitor would allow for finer tuning to higher "Q" and consequently higher voltage. Results are already awesome!

I bet the Chinese inventor burned a trimmer cap out fishing for high "Q" then replaced it with the two additional 0.47uf resonators. You may need to start over to find the correct combination.

Merely a few centimeters difference in coil wire length can offset the LC "Q" enough to reqire an adjustment in the picofarad range. Fine tuning can double the tank voltage!

This is like getting real power from VARS. Phase angle Voodoo? I wonder if power would rise to meet the load if you put the reciprocal saw to work?

The Dielectric field is powering the loads. JEG's illuminated bulb should stay lit submerged in water!
Tesla's Hairpin circuit plays the same trick capacitively. Master Ivo's setup amounts to basically the same thing.

Hi Synchro
The Chineese eng. use two caps of 0,047uF (not 0,47uF as i wrote above) in parallel with his ZVS primaries, total input capacity of 94nF/2000V. The in series cap is of 22nF/8000v capacity. In my case, by using a 100nF at the input, it rings at 110KHz. I needed a 10nF-12nF capacitor at the resonant circuit to tune. I was thinking to match the impedances between the separate circuits by using Don Smith's nomograph. (I attach it below). But the Chineese seems that he didn't bother with that. Nevertheless he feeds successively a 2KW load running it at 198-200Volts!!! So according to what i see on my bench, he might has a secret ingredient which is hidden!!??

The fine tuning is off of the table for me. Each load you add, changes the resonant point of the tank circuit! If i was to match the impedances by using the nomograph, i would have to go down to 30-35KHz to meet a 30-50 ohm impedance which suggests a load of about 1.5KW. But clearly this is not the point. The capacitors he uses suggest an impedance of about 100-150 ohm. Something doesn't fit here. So everything point out that the Chineese uses a separate technique to raise his voltage across the tank circuit. Time will show. :)

what I noticed: you can vary the frequency from that semi-adjustable resistor

The 5 turns are in parallel that make as much as a turn but has a high current
the 28 turns would be equivalent to the 3 turns in Ruslan's system with high current and high voltage at serial resonance.

Thanks conico. If the frequency is matched to the primary LC, will this circuit behave as a ZVS driver?

No, it is 5turns in series but made out of five wires in parallel. Like 5T with very thick cable.

Post by: Jeg on February 04, 2021, 06:15:11 PM
Yes, there is no space at all. But i saw his video and i counted them turn by turn. It was difficult but he did it. Perhaps the real diameter of his wires might be smaller than what they look like. I tried with 1mm on same core but i had not chance of doing it. I made it only by using 0.75mm wire for secondary and 4mm primaries on the top.

ZVS means zero voltage switch. See mazzilli driver below. It switches when voltage is zero and so it handles heat much easier than normal push pulls. I was just wondering if a normal push pull will operate the same if we attach a cap between drains like the chineese.

do not use any capacitor in the oscillator with mje13003 I think it is just astable  oscillator and the capacitors are even in the coils  if you want to have the same frequency as the Chinese type, you must have the coil of 8 turns to be 150uH and the one of 11 turns 250 uH.
 So , if you do't have 150 microH on 8 turns make 9 or 10 turns or 7turns. The same on 11 turns , if you don;t have 250uH make 12turns or 13 turns , and is enough to have  the same frequency of the Chinese guy. Do'nt edd a capacitor like in mazilli diagram it will change the frequency dramaticaly.
In the second ferrite transformer you see there are 5 turns from 5 wires but NO is just one turns from 5 wires in parallel.
 See mazilli diagrams  where 5 turns is for IRFP 260 with R( DS) on 150 mili ohms but  the the Chinese guy use IRFB 3077 with R (DS) on 3,3 miliohmi. That means he use just one turns. With just one turn you will have more votaje and more amps.

I want to know your opinion please.

If one assumes an induced value of 100 Gauss for the electromagnetic excitation of the coil winding in the mean cross-sectional diameter of the coil winding without the soft iron core, 90 the nickeling receives an assumed value of the magnetic flux density after the insertion of the indented core according to the schematic representation 1000 gauss. This 1000 Gauss magnetic flux density (field line density) is integrated at the moment of the introduction of the complete current-carrying coil between two field magnetic poles with a magnetic flux of, for example, 5000 Causs and thus added to 6000 Gauss. With the simultaneous flow of the increased flux density through the coil in its longitudinal axis in the same direction of its own magnetic flux, the current voltage in the coil is suddenly increased by this self-induction during the ongoing rehabilitation of the magnetic field in the coil winding between the field magnetic poles. [0018]
This induction increase in the voltage, in turn, retroactively increases the magnetic flux in the coil core and in the entire machine system, possibly by a further 4000 Gauss or more, to a total of 10,000 Gauss (= 1 Tesla).

In this way, the initial value of the magnetic flux density of the value 1 is brought to the value 100, without an additional quantum of electrical energy having to be supplied in the functional sequence. In this way according to the invention a relatively high magnetic flux density is achieved as a result of the installed energy with little energy supplied, with which a very considerable torque can be generated in the machine according to the invention. t) The induction in the present case does not directly cause the torque itself, but it only contributes to the increase and addition of essential forces to a maximum of usable force and thus simultaneously allows permanent magnetic forces to be used and their cumulative integration with electromagnetic forces for conversion into a considerable torque.

What is here the claimed effect ? coil number dependent ?!

do not use any capacitor in the oscillator with mje13003

Hi conico.
I am talking about the capacitor that the Chineese used across the drains of his mosfets. This is at the second ferrite transformer and not at the oscillator side.


In the second ferrite transformer you see there are 5 turns from 5 wires but NO is just one turns from 5 wires in parallel.

You know that experimentation has no limits. You can test as many turns as you like across your primaries or secondary. But if we are to replicate the effects of the Chineese we have to stick to his circuits. His ferrite core has 5T in series per primary. As i already told you i have seen his movies. By experience i can tell you for sure that one turn primary will lead your mosfets to destruction. We have 24V input over there. Even by using 5T the current is already huge at the input. By using the caps of the chineese you will consume about 10A. If you also experiment with impedance matching, your input current will grow even more. My best output until now takes place with 24A at the input!!!

There are a lot of issues more though. Like for example...have you noticed that the Chineese doesn't use any choke at the input? What about saturation??? Why he doesn't saturate his core with just 5T at his input? His core is without any kind of gap...think about that.

Look at the total length of the wire before starting winding. This length corresponds to more than 1T. Close to 5 like in the drawing. But feel free to test your idea. I'll be here to discuss it if you like.

 Maybe he make 2 turns not just one, 5 turns make a low voltaje and to low amperaje.
Yes , the 5 wires are long but he can make maxim 2 turns not 5.
 An other explanation . you can see the ferrite road is very well isolated with paper or plastic , the wires do't reach the ferrite part because the voltage is high.
 the question is where the secondary with 28 turns is wound?

Jeg :

If the wires in the center tap are separated from each other, the amount of current cannot be collected, but since they are connected, the only function is to convert the ferrite's magnetism into electronic energy.
Since ancient times, the role of ferrite is all about energy conversion.

I just predicted.
However, there are two main types of free-generators that are open to the world.
It is a'captor' that uses magnetism with a kappa-type generator and magnet or transformer that activates the earth-ground by using high voltage.
Because, the principle of free development is almost all of these two,
If it wasn't for this kind, I would have prepared a vendor and a patent before publicizing it.

So, the Chinese generator is more than 90% likely the result of applying the existing technology, and I will cancel my opinion anytime if it is any other technology.
I think that there will be enough technical positions for generators that Jeg members are interested in.
I have no other reason than to approach it from a visual point of view.
It's a life that has lived through the eyes of power for many years, so one notice is a bit faster than others. ;D ;D

According to other videos of him, i understand that he is very smart, he knows Tesla tricks, he is a spark gap master, and high voltage is almost there in all of his experiments. Especially some very small converter/modules for HV, i see them often. But, except of a capacitor that he uses here with 8000V ratings, i don't see any other component on his board which suggests HV.

You are right about the HV ratings of his transistors, but this stage is for driving just the gates of the mosfet. If anything more than few volts over there, it will short the gates!

Now I saw. in the Chinese scheme is an important information. Secondary must be 180v for 14 turns, that means 12v / turn. in the transformer primary must be the same. 24v from batteries and 2 turns will be 12v/turn in primary.
So will not be 1 turn or 5 turns , will be 2 turns in primary and 14 turns in secondary

Guys, those videos are already in public. The Chinese engineer shows the basics in the construction of this very efficient inverter. He probably has hidden his real techniques which make it so efficient, but this is ok as it is not the first time that inventors try to protect their stuff and hide things. Nevertheless it is one more great project for doing your experiments.

This is not a generator, but a DC amplifying converter.
The reason why the Chinese use DC amplifiers is,
DC220/DC380V is still commonly used in factory automation equipment.
Because DC motors are more convenient in speed control and direction control than AC motors, they are still commonly used in factories in China.
Electric shock accidents can be a big deal, but Chinese people don't think much about this.

China's DC220V automation device was popular about 10 years ago in plastic-house farming in Korea.
There are several vinyl houses that are still in operation.

Hi color
Thanks for your comments! ;)
Yes it is a mix of DC and AC power signals.

I should tell to the people here that this device is deadly, and color is right. A small mistake could lead to instant death. We are talking about 200-300V in a 1000uF cap bank. I tested with smaller output caps (1-10uF) and it works with the same efficiency, so in the future i will change it.

 Please take this thread as informational only and don't try this if you are not confident of what you are doing. Device is not OU up to this point at least, but a very efficient inverter. It is a kind of fun for me watching a zvs driver producing so much pwr. It takes the advantage of the in series circuit energy, to pump the output load cycle by cycle. I am not wondering why Ruslan based his circuits on this kind of operation.

Keep it safe alright??!!  ;)

You watched the video well.
Jeg, like my dad, is like a teacher with outstanding talent in various fields.
The generators of Akura and Ruslan do not use commercially available PSUs (220-24/12V-6A~10A/170W~350W), but also operate with a simple diode bridge-transformer (generator output-24/12V). This is possible.
Simple homemade-transformer is safer.
The Ruslan generator also has a feature that the more output there is, the greater the input voltage.

In my view, it is almost perceived as a complete converter, but if it is made larger, it seems to be marketable.

If Jeg is still interested in the Ruslan Generator,

So, If Jeg is still interested in the Ruslan Generator,
May I have a suggestion for Jeg.

The schematic below is a bit incomplete.
Can you complete this schematic?

Hi Color ;)
I hope this will work for you.
Enjoikin's circuit has many flaws and mistakes. Using tl494 for HF is a waste of time. Mama company suggests to work with it up to 300Khz. Enjoikin overclocked it but still it is not the optimum way.

In place of TL494 i built a gate oscillator able to go up to 6MHz. By using 1nf for timing capacitor i have a control between 100KHz - 2,5MHz. But If you go to picofarad range then 6MHz is possible. In my board, with no capacitor at all, it reaches a frequency of about 6,5MHz.

First circuit, takes a pulse at the upper left corner, and creates a pulse which is controllable in phase and in width. This pulse goes in to a mixer with the HF oscillations and there you are. You have two outputs here, one normal and one inverted.

Second circuit in addition it uses an extra oscillator which can drive/modulate the HF pulses without any external pulse. This circuit can work as a sync like before, but it can also work as a stand alone burst generator without the need of an external pulse trigger like in the previous circuit. It just needs a small jumper or a switch, to connect the modulator in to the circuit as long as we don't use it for synchronization. So two operations in one board. The drawback in this second circuit is that it outputs an inverted waveform so it also needs an inverted mosfet driver like tc4429. The reason for that is that i used all my available gates and didn't want an extra IC just for one gate. But if you have space for one more IC, then build the double output method like in the previous circuit.

I hope later i will find some time to make a small demo-vid.

Regards

I promised, so I will post how the generator works.

Hi If you go through all the Ruslan stuff Russian and Lithuanian publications his device (grenade) is a mathematical equation
meaning the need to stick to that equation or alter the whole device to all mach up using the new values in that same equation.

I don't want to go into that too much here but  he used a push pull out put of each side of 18 Khz thus equaling 36khz total
and wound his grenade with 41.64 Meters of wire.

I can't prove this because I haven't built or experimented with such a build nor do I intend to but there is a man who has
dissected one of his 200 watt devices.

here is a digital replacement of the LM494 circuit of sorts using a 4013 one to produce a 50/50 sqr wave and another to
decide two equal dead time (to reduce zero crossing current and over heating) outputs using 2 CD4093 chips.
the device should be easy to phase lock the katcher and grenade and divide down from a phase lock VFO.

The resister was a 3K3  and the preset a 20k
Te caps were 220pf and a 4700pf

새마을 노래(박정희 작사·작곡)

새벽종이 울렸네 새아침이 밝았네 / 너도 나도 일어나 새마을을 가꾸세
살기 좋은 내마을 우리힘으로 만드세

초가집도 없애고 마을길도 넓히고 푸른동산 만들어 / 알뜰살뜰 다듬세
살기 좋은 내마을 우리힘으로 만드세

서로서로 도와서 땀흘려서 일하고 소득증대 힘써서 / 부자마을 만드세
살기 좋은 내마을 우리힘으로 만드세

우리 모두 굳세게 싸우면서 일하고 일하면서 싸워서 / 새조국을 만드세.
살기 좋은 내마을 우리힘으로 만드세

1) The 4,7nF capacitor goes to pin13 and not to pin8 as you have made it above.
2)The IC we want is the 74LS132 schmitt quad nand gates. Without the letter "D" at the end which i think is the smd type of the IC.
3) In your drawing you forgot two more gates so you need one more IC for them. In total you will need 3XIC's in a total of 10Xgates. Look the original circuit again above.
4) When you finish your board you need to attach 100nF ceramic capacitors straight on pins 7,14 of all your three IC's
5) I am afraid that you will need an oscilloscope to adjust and learn the behaviour of the board.

That is the associated video which will give you an idea of the layout.

The business of modifying/upgrading old ready-made items to new ones is one of the most thriving businesses around the world.

This is a good example of how a promissing thread got totally diverted in to the ground. Yes. The agents live amongst us.

Mr Plasterer  Perhaps Jed has a ware house full of old Low Power TTL devices  ;D ;D

At some stage Ruslan bless him  :o let the cat out of the bag in the Russian language
when he started selling his devices some where on this tread the young lady on this
thread posted a link to it not all that long ago but it's such a mess god knows where
it is now, but its still on here only find it and go through it all.

There is this posting some years ago that works as far as generating the timing
pulses is concerned. I knocked up the first 2 stages on a bread board the delay
and the pulse width section and fed it with a CD4047 oscillator and used a CD4093
at 15 volts and it worked well after a bit of experimentation but ran out of components
after that  8) :-\ :-\

Regarding Color's 494 circuit I couldn't get the 494 to lock on the correct place  and
it kept trying to lock while having some kind of unstable  'twitch' where the data window
appeared to try a synchronous lock, It was just a wast of time. Any way such is life.

Yes too sloppy here
And a bit vague on what is being said


I think a new fresh separate topic at all forums will be good !


For teaching purposes ( educational tutorials on how to save our planet


Also we have “open source” experimenters in need of equipment ( India and other places)
And probably funds too or at least parts





Not just one mans opinion

OK, I have been pondering this design for a while but I suudenly noticed Mr Li is using Litz wire every where!
