He did not get it to self run, so why the need to translate?  And he did not correctly wind the copper tape. Tape must be between windings.
Also, this guy is using inductive wirewound power resistors that will block high frequency currents.   Such resistors are good only for DC and LF.

Both of those are significant construction differences.

[size=78%]He not get selfrunning, so why need translate? And he not corect maybe wound cuper tape. Tape must be betwen winings.[/size]

Hello:

Ok, I understand that it is NOT self running: but considering we need a suggestion on how to place the Ground Plate within the L1  & L2 coil, it is a start.

Please see attached purposed winding configuration for L1 & L2:

You say:  "Tape must be betwen winings"

OK, please suggest where and between which windings to place the Tape or Plate of Copper?

Thanks in advance.  Peace

The author of this video says that he does not know how, but his device powers a 200W LED flood light (to unknown brightness)  without any hidden batteries and hidden wires.

To analyze it properly, I need scopeshots of simultaneous current and voltage waveforms on both windings of the transformer/choke.

Hello:

Just a quick observation in regard to the above video:

The L1 and L2 leads, two for each winding are noted, makes a total of 4 leads between the Circuit board and the Transformer.

My question is :

Where is the single lead for the Ground Plate?

Is it hidden or is it NOT needed?

Thanks , peace

Dear lost_bro.

I too, noticed the absence of the shield!! In my preliminary tests with the transformer wound to the above posted schedule an external ground wire from a rod, not Supply industry ground. I found the storage capacitor drained faster !!

Some have suggested that this shield could pose as a "virtual ground" or collector ??

Going back to my original post and looking at the transformer presented on the schematic drawing. It DOES suggest that my schedule may be wrong . My reasoning behind this is because the starts and finishes are at either end not as mine, picture attached below.

Cheers Grum.

The plate could be connected on the bottom side??  If you look at the lower right corner.. you see one of the wires goes to the bottom side.

Edit: NM.. just realized you're talking about the transformer in the video.. didn't read carefully.

So maybe someone who speaks russian can ask this guy how he wound his transformer and why we dont see a 5th wire, that is connected to the 1turn-coil/shield? I also wonder why he only needs 1 tiny heatsink for his build, this seems to me like there is only very small input power to primary coil. On photo of akula schematic there can be seen big cpu heatsink + cooler.

Hello From other Planet:

Yes, you are quite correct with the observation regarding the Heat Sink disparity;

Akula has a very large Fan cooled heat sink, which now poses another question related to powering that fan which cools the large heat sink:

Where does the fan's power come from?

Is it running also from the same circuit, and if so why does the schematic NOT show this connection?

I would assume that the fan is consuming at least a few watts of power, so it is an issue to be dealt with as well.

Thanks, peace

Hello From other Planet:

Yet another mystery to be dealt with:

The posted schematic from the U-tube channel does NOT match the Blurry Schematic shown in the Video of the Self- running TPU.

I could not guess why one schematic is shown in the video and another very different one is shown as a linked reference.

Thanks, peace

Hi,

That video is nothing special as guy there tries to explain MOSFET driver operation and nothing is there about transformer or how to achieve OU effect..

Cheers!

I wonder why the transistor gets so hot.  Heat is wasted energy.

The one turn copper coil in the video was shorted, wouldn't work that way, insulate the two ends.

It also looks like the transformer pictured in your post 4tesla has s split core and split windings. Probably with a modified core to shunt the magnetic current.

It has been suggested that it (MOSFET) might run in Avalanche mode..... I have seen other Russian videos of self running devices that complain of excess heat dissipation from the MOSFETs; causing instability and as a result only permit the device to run for a very limited amount of time.

Yes, heat is a waste of energy if you don't need the heat for another process, in this case it is apparently  the result of the process we are chasing.....

Oh it is a MOSFET.. my bad.  Strange as it is rated at 110A.  Being a 30W circuit you would think it would be only about 3A going through the circuit.
