Jeg :

Simplified Chinese characters are sometimes known only by the creators.
In many cases, even a little change according to their own style can not be recognized by a Chinese doctor. ;D ;D
But you can see what the letters mean.

The first letter means 'wind' and the back letter means 'fan'.

Usually it is called 'balloon' or 'Adballoon'

If there is a'balloon' in the positive voltage of DC, it means the strength of the voltage.
12V/24V/36V/48V........
It means that the generator can be operated even if the input voltage is high or low. ::) ::)

Jeg, thank you for posting those videos. It becomes clear to me how transformers should be made.
if you still have movies about this Chinese system, please post so that we can replicate it as accurately as possible.

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.

ps1. I don't know if it is possible, but it might be better if Ramset could download those vids and upload them again under the account of Overunity.com

ps2. Comments are disabled in the attached videos so anything you need to say just do it here open-sourced and get your answer.

I could try to reach Stefan to see if he would do that ?


He seems not to easy to reach lately, much going on just surviving with all
The Covid issues!


Thanks for posting theses.


I will try to reach him , there is also another topic I was hoping to ask him about  .


With Gratitude

Jed Hi, thats great concerning the video's  but any chance they can have the captions enabled ?

as that would be terrific as then we might be able to catch-on what he is saying  :o

Many thanks SIL

Maybe color or one of his family can make some key points clear ( quick summary)
I was doing this with a French member in Stela thread ... however Stela got strange with that topic
Removing his vids , so I am waiting to post again until we see if he really has some plan ?( I removed my summary before topic timed out with edit / time limit!



Regardless
We really do need more open source members from Asia !


Respectfully

Guys  I can't do it. I check Chinnese in the language option but after saving changes it returns again to English like i never checked Chinnese. So plan B for finding our assian friends needs to be activated!

Conico
I really dont know what someone could gain by winding the primaries this way, but you might have right my friend. It looks like two turns per primary. Probably he says how many turns we need in his video. I hope color will find it out!

Masterplaster, lancaV thank u guys! So interesting effect!!! It worths a try definitely!

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??!!  ;)

PART 2. Experimenting with different impedances for higher loads.

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.
---------------------

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?
As you know, my dad doesn't have an oscilloscope.
You must have an oscilloscope to find an unstable element in a circuit.
All about approaching circuit gates with basic common sense.
The members of this café just eat the prepared sacrament and don't seem to want to give it back to everyone.

If Jeg completes the schematic below, I'm willing to provide the other half of the generator resonance to Jeg as well.
Jeg, only for individuals.

I would appreciate it if you thought about it enough and responded.


P.S

This offer is valid for all members.
Challenge yourself if you are interested.
Of course, it is rewarded personally.

They are boring lives with nothing to do in their old age, so it will be fun to try them for fun.
Since an appointment is a promise, I will give preferential treatment to members who first open it to this cafe.
Jeg members are provided separately in any order. ;D ;D ::) ::)
