In this thread I will be going through the information provided by YoElMiCrO on ferroresonance.

I will come back and resize the photos if I have time, but want to share my experiences meanwhile.
First photo are from the first diagram on YoElMiCrO's thread:

I am using IRF3205, and the gate driver given on the diagram. I wound two transformers on EI33/PC40, I have a few 3c90 cores on their way which should get better results because they have less losses etc. T1 is 16 Turns.

T2 I used the formula provided by YoElMiCrO: N = H(Oe) le(cm) / 0.4*Pi * I = 40 Turns.

CH1(Yellow/Voltage at Drain), CH2(Teal/Voltage at Bulb), CH3(Pink/Gate), CH4(Blue/Current probe after bulb):

T1 WaveForms:

T2(40T) Waveforms: While scanning frequencies, i've came across a point where every other cycle the waveform or reaction changed, at one point you can see the wave roll untill it stablized into the same wave each cycle, shortly after it reverted. Not sure why this is, but heres a couple photos showing what im talking about:

Vidura is correct, everyone should be testing and replicating these simple experiments, and work to grasp an understanding of the complex things going on. Thank you YoElMiCrO for sharing this and providing a path that we can all learn something very valuable.

I already have a PIC programmer, I have more cores, PIC's, and all other IC on the way to continue exploring this phenomenon. Im familiar with C and C++, but will start learning assembly language to be able to configure PIC, hopefully YoElMiCrO may be able to source some code used for this experiment.

This circuit is the second in the thread:

I never explored or looked into the miller effect, and had to change the mosfet I was using to achive the waveform although is slightly different so may not be exactly right, there is plenty to continue to learn.

CH1(Yellow/Voltage on Drain), CH3(Pink/Gate): Frequency: 82Hz Duty: 0.8%

Hello everyone.

@AlteredUnity.

Okay, you replicated the two circuits 100%, thank you.
It is clear that as soon as the circuit is finished
that I designed for Fighter ZPM with an MCU will be
published to the source, this time in C.
But for reasons of time I haven't been able to finish,
I have a lot of work to do at the moment.
Excuse me.

YoElMiCrO.

Great to hear YoElMiCrO! No rush, it took a while for me to find time to try this experiment, and I can tell there is still a lot to learn and try, so meanwhile I will continue with what I have. Thank you.

Interesting demonstration alteredunity, there are a lot of things to be experienced in this thread.

Thank you to share this

Hello gentlemen

This is an interesting circuit. In effect, the circuit looks like a boost converter without a blocking diode. I built many similar circuits minus bulb 2 as a battery pulser/desulphator in the past. Bulb 1 was used as a current limiter prior to T1. When Q1 cycles T1-C1, an LC circuit, it produces a high frequency dampened series oscillation through the battery.

On the circuit shown, we should remember that T1 is not a transformer because it has no load and acts like an inductor. Therefore B1 would tend to see a series current through the battery, B1, T1, C1, B2. While B2 represents a parallel leg of C1, B2 and Q1. B2 should light while B1 does not because C1 can be charged to the source voltage plus the inductive discharge voltage from T1 and discharged through the lower resistance path C1, B2, Q1.

What I always found strange about many boost converter and older ignition systems was why they would in effect short/waste the energy in C1 simply to cycle the inductor. In effect, in the circuit shown, B2 is indicating an amount of energy in C1 normally wasted in many circuits.

My solution was to do away with Q1 altogether and switch the charged capacitor C1 out of the circuit completely and replace it with an uncharged capacitor C2 to charge T1. Similar to the capacitor switching circuit proposed by Tom Bearden found here, https://tesla3.com/tom-bearden-motionless-electric-generator/. In effect, Q1 is removed and C1 is replaced with two capacitors and two H bridges. This may be what Bearden was getting at with asymmetrical regauging.

Sorry I haven't been active, been really hard to get free time these days. However I wanted to understand more about ferrites magnetic properties. I will add to this post when I have time, not everything is correct just posting while I have a chance.

I wanted to measure where the datasheet specifies Bsat = 330mT. This is a ETD39/20/13 3c90 core. c

Measuring BH Curve: There are many sites that helped a lot, I will post once I find them again.

This setup N1 and N2 have 28 turns.

R = 3.8k

C = 1.037uF

f = 300Hz, 3.3% duty

RC >> 1/2πf, in the pictures I took in a hurry I did not check this.
Ideally if you make R×C = N×Ae ; since B = Φ / Ae , also Φ = R×C×Vo / N; Then Vo = B
- Vo = Voltage from integrator output
- Vin = Input voltage: 12v
- Ae = Core cross sectional area: 125mm^2
- le = magnetic path length: 92.2mm or .0922m
- N2 = number of turns on secondary: 28
- Φ = R×C×Vout / N2
- B = Φ / Ae
- B = R × C × Vo / (N2 × Ae)
- Vo = Φ × N2 / RC
- H = N × I / le

Other formulas used:

Φ = Vin × ton / N : 41.25 uWb
ton = N × Φ / Vin : 96.25 us
L = N × Φ / I ; Vin / (dI / dt) ; V × ton / I

Take a look at the current and the change it goes through while permeability changes as flux density is increased with time - Ch1(yellow/current), Ch2(blue/Vo); B =(3,877×0.000001034×0.2887)÷(28×0.000125) = 330.67mT :
