Hi Sven,
Your core is already over saturated. When saturation is reached there is no point in putting more energy into the core as it acts as it has vanished. The inductance of the coil wound on the core is then acting as it has become an air core. To harvest the energy from the parametric change of inductance the working point should be around the saturation point. Just move back and forth between the linear region and slightly into the saturated region to use the great change in inductance.
In the linear region the oscillations are sine waves. Your curve of the current has spike like peaks on top of the sine curve which happens because the core saturates at these points. Most of the inductance then disappears and the current is free to flow almost only limited by the resistance of the circuit.
Regards
Ole

Hi Ole, I want to reap this short extreme peak. The high-Q with an iron core is indeed the Ferroresonanz which is not linear, I still hope that I reach this state with less energy or reach an even higher state so that the input energy decreases. The Q-factor is about 20. This condition with lower energy can be reached so that the factor increases to 100 as an example. Greetings Sven

Hi Sven,
"I have uploaded a Scope image with extremely high power, for me it's high-Q, is that high enough?"
High enough for what? How much amplification is needed?
Have you found the free energy yet? This ought to be the primary goal. I don't see what the purpose is for that super high efficiency. If it is for energy storage a battery would be a better alternative I guess. A battery may not be that efficient but if having free energy that really doesn't matter that much.
"I wonder if it is enough to simply pulse the drive coil like a flyback converter to generate resonance energy in coil C."
Yes definitely. As long as the pulses are shorter then the frequency of the oscillatons this will actually be a great way of resonating a system. That was the way the master of resonance N. Tesla did it by using ultra short pulses.
Cotnoir just showed the latest selfrunner. There are many of them. The principle looks very simple. Just use the principle and make a simpler device and don't use mechanical relays like he did. I'm building a hex MOSFET bridge to try some experiments along that way. This is still a scale model compared to Pierre's device. Pierre's next model will take him three to six months to build due to limited time. My progress is slow too due to same reason.

Hi Ole,
the device of Pierre Cotnoir is too complex for me, I still keep it with the transverter, I think the goal is always the same only different approaches.
I have uploaded a Scope image with extremely high power, for me it's high-Q, is that high enough?
The 3-phase transformer that I have is wound with very thick copper enamel wire no matter how I connect it the ohmic resistance is very low the inductance naturally increases strongly.
Am now at 1.5 kv peak and 3.054 kv peak peak.
So I can of course more reactive power drive with smaller power and the temperatures are not so high and the power is still sharper.
What interests me the most, the Hector with a 3 Watt Pulser a 3 phase Transformer resonated with great reactive power.
I wonder if it is enough to simply pulse the drive coil like a flyback converter to generate resonance energy in coil C.
Since each leg of the transformer has a winding wound bifilar one could also use these to drive the drive coil as a push pull with short sharp peaks, such an inverter would have to build then probably.
Honestly, I'm doing a little hard with that, because mostly the IGBTs were destroyed after a short time, the topic Snubber is already a case in itself. I've got a couple of SiC mosfets around here to play with, maybe they're more resilient.
I now have everything to play with the transverter with batteries, unfortunately I do not have the time to do this for professional reasons.
But I read all posts at least that are related to the subject of free energy.
Best regards
Sven
