Kapanadze Cousin - DALLY FREE ENERGY

Hi AG
Yes it seems that works in resonance. In series resonance like in Ruslan's device. It is so impressive. For sure it consumes a lot of current. But how much current a welding maschine needs? He works on camera none stop for a half an hour! Do you think that his batteries can afford all this load? 
The published circuit does not correspond to his result...of source!

Hi Jeg, built this Oscillator section of circuit diagram you published
up as far as the FET gate drive  on some plug in board.
Here is the wave form, Im not going any further as i cant get the ferrox.
and not so many interested. None are but nice spikes though.

Hi AG
Thanks for sharing. I have also built a mazzilli driver for the tests. Very primitive but superior in relation to the simple push pulls when it comes to heat! Looks like it can work for days with 6A at the input without any significant heatsink!

    Geg:
   I also had some fun along with Geo a few years back with the Mazilli drivers. That driver can also get hot, depending on the load. 
  And I had blown my share of fets, as well, when I used it to run the yoke/grenade circuits, later on.
  I think that I got it up to running 700w load of bulbs.

Who ever is interested,

When I built a TL494 circuit and driver ( few years years back now) again on plug in board
I noticed a strange thing about connecting the yoke 2 wingdings  to the FETS

one way it produced a square wave and a ringing attenuated wave that switched a lot of current and heated the yoke.
But  if one driver winding was reversed to on one of the FETS output wingdings it produced a huge high voltage spike
and really low current much like the Chinese driving oscillate circuit Jeg posted.

If you play with this idea watch you don't damage the FETS over voltage limit of the FETS.

Yes it can build heat eventually with large loads. But in general due to its operation (switches when voltage is zero) it is nothing in relation with the normal push pulls. Nice toy for experimentation for large currents.

AG
Nice observation. If one coil is reversed then it induces current when the other coil is on the run. (through the mosfet body diode). Also it has direction towards to power supply and so the decrease in consumption current.
The higher than normal spike is due to the autotransformer effect. We have the addition of energy of two spikes together.
