and here he seems to explain schematic: https://www.youtube.com/watch?v=EwCS15pRtH0&
really bad i not speak russian 

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 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.

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.
