Study of Transformer Resonant Overvoltages Caused by Cable-Transformer High-Frequency Interaction

In case there is any misunderstanding, the video was not mine. Someone else made it, but it is very interesting. I have an idea as to why this behavior occurs with coil shorting. That it has to do with Lenz law and core saturation. Essentially the shorting the secondary introduces a sudden loading and the current must rise to meet the requirements of the load, but the core is already near saturation and so the current in the primary cannot rise and the result oscillations between primary and secondary as the core moves in and out of saturation.

Hey Zanzal,

I would like to present a slightly modified theory if I may?

We discussed these ideas in the Timing Thread. It is Timing that's important to think about. We saw in the video, the Circuit modifications were being done at Sine Wave Peak, an important concept to understand. The reason is Energy Transformation. Don Smith said:

Useful energy occurs as the result of imbalances in the ambient background energy, which is a transient phenomena. In the electrical field, it is a closed system subject to heat death, which severely limits it's utility. The flip side of the electron, produces magnetic waves which are an open system, not subject to heat death.

We know for sure, and this is important, Energy transforms from Electric to Magnetic, then from Magnetic back to Electric, for example in an LC Tank Circuit:

Energy moves from the Capacitor into the Coil, transforming from Electric to Magnetic, at 90 degrees, all the electric energy is now magnetic. this process then reverses, all the Magnetic energy transforms into Electric from Magnetic and the process repeats. Of course losses damp the LC Circuit, but the LC Circuit is the most efficient Circuit we build.

I posted the following circuit, as a pseudo circuit, I notice now I missed a diode on the VE- side of the cap, in the same thread:

When tuned to the optimum point, the input current will fall to zero. Now, this implies tuning, and we know this is a requirement. This circuit is perhaps one of the most simple, but most amazing circuits ever posted to this forum and none have replicated it.

Zanzal is correct with Saturation, at peak Input Current, we are up the leg of the BH Curve. However, our machine is falling out of Saturation after this point. This means our Coils Inductance is also changing, from low to high. We know from experiments that the coils inductance changes with the Magnetic Field. This modifies the Rate at which Current ( I ) can traverse the Coil, which is by definition, the Inductance.

We have a Coil which has a Magnetic Field that is reluctant to change because of our changes. This also means the Inductance is reluctant to change, which means Current can traverse the Coil easier for longer.

The current and voltage initiating fields are in such a direction to either accelerate or decelerate the rate of flow of charges depending on the applied polarity and voltage amplitudes.

As polarity may be maintained constant, that polarity of acceleration should be chosen so charges move at faster rates, lowering copper duty factor, at the same time opening the gates wider so more coherent field entities may enter for the conversion process.

It’s obvious, we have a self-regulation machine whose inherent conservation to the nth degree.

Its not magic, its understanding and its simple once this understanding is obtained. We are building machines that yesterday we were only discussing and had no idea on how they worked!
