Overunity transformer effect

[tinman]

A simple little project with some interesting results and effects.

Below is a schematic of the DUT.
The transformer is just a 2:1 transformer-->nothing special. One of the inetresting effects is the ability to get the secondary winding to ring while the primary winding dose not-->and yet both windings are wound together on the same former. You will also note that the voltage across the secondary(blue trace) remains for twice the time duration than that of the primary(yellow trace)-->even though it is driving the LED. The scope shot below shows these two effects,and have attached the schematic as well-along with the first video.

Hy   Tin  Man  ,very  interesting  ,I  will  like  to  try   with  abiger  traffo  and  see  if  come  out  some  20  watt   lamp ,
wath  do  you   think  ,is  safe   to   try   to  bust   10  kgr.  traffo    in  this  configuration

Open circuit you would normally get 2X the voltage across the secondary that you get across the primary.  You only get 3V across the secondary because the  the 50 Ohms of the function generator looks like 200 Ohms in series with the 2X secondary and the LED easily clamps against that.  If you move the chl 2 probe to the primary you should see that the voltage there only comes up to about +1.5V.  That means that during the pulse high time of the function generator, (1.5V)²/50 = 45mW is being dissipated internally by the function generator.  This is comparable to the power that is delivered to the circuit, meaning that the circuit is roughly 50% efficient.

Tinman,
Perhaps you already know this...  If the winding in your primary were 1/4 the size/weight of that in your secondary, would you not then get resonance in both sets of windings?
I am thinking of course, of Tesla's Magnifying transmitter.

But maybe you're not looking for resonance on both coils.
According to Eric Dollard, any time we drive a coil to resonance, we separate the dielectric component to one end and the magnetic/current component to the other end:

When you experiment with a resonating coil, you find that all your magnetism then appears at one end and all your dielectricity appears at the other end, and you have a difference in these electrical discharges which occur off the end of this... which will occur back to the point at which they started from. And you can hook a radio frequency watt meter or amp meter or whatever you want here and there'll be actual initiation of very heavy flows of energy, all of which are reflected back to the coil, except that utilized by the load...

How to access the dielectric component might be a question worth entertaining.

Why don't you ask Eric Dollard that question, I'm sure his answer will be quite "entertaining". Especially for people who work with resonating coil systems every day, like radio engineers, and _real_ Tesla coil theorists like the Corum brothers.




Eric Dollard says a lot of things. Unfortunately, not very many of them are actually correct.
