See some of my simulations, it can be useful. But please correct me if I'm wrong...!

keep in mind simulations work on known principles(formulas), they for example wont show Longitudinal wave effects.

Hi Ivo,

I've began with the work, and I'm stocked by the testing of the circuit. The switchings are relative clean (tested with a resistor), but as you can see at the scope pictures, if I increase the frequency, the duty cycle of the square waves will be less, even of unequal manner in both side (high-low). My signal generator gives a good signal shape directly checked with the scope. I do not understand the phenomenal. Do you have any idea or did you see something similar?

My other question: the pancake coil gives me a pure resonance of about 600 kHz. It's a beautifull dampened oscillation, but we need rather only ONE fast, large impulse (the first part of the resonance) and not like this. How do you achieve this like in your 2019-12-14 video (see attached)?

Thank you!!!

fejleszto, very cool to see your version of the radiant half-bridge PCB working.

I have no Idea why the duty cycle changes. Suspect something to do with the ground of the square wave signal?

check If you bridged the source to the negative of the gate driver IC

The damped ringing of the L1 coil, suggests you have not connected the series resonant L2 coil (and its series capacitor) to the half bridge.

the series resonant L2 provides a low impedance path to ground for the energy of L1, during dead time.

So dont use 50% duty. use 49% or even less.

when L2 is perfect series resonant the impulse of L1 will not be visible, as it is fully absorbed into The series tuning cap of L2.

when tuned slightly above resonance, the impulses will appear (voltage probe between series cap and L2). these impulses are the voltage half waves of ringing L1 (energy is transferred into L2)

I don't know which isolated dc dc you have used, maybe that could also be a cause for the duty cycle problems

Hi Ivo,

thank you for the very fast answer!
I've found a solution for my problem: if I add +2,5Vdc offset to the 5V input signals (square waves) with the signal generator, anything works just fine at all frequencies!!! I don't understand exactly why. The negative inputs of the drivers are grounded. Perhaps the two sides should be better separated, I dont'n know...

I understand your answer in terms of damped ringings and so, I'll keep working.

great that it works. the offset makes sense.

your last scope shot shows only the negative impulse, keep in mind both polarity impulses will show up alternating, but a symmetric power supply must be used for that (earth ground in the center between + and - dc supply). ground the l1 and l2 on earth

I use symmetrical PSU.
So, I have the huge impulses, both side + and - ;)
What is the real importance of tuning L2? I achieve maximum peak voltages at different frequencies, but it has nothing to do with L2 resonance I think...
(L3 is at the moment out of game yet)

@evostars

Have you considered using dual devices? i.e. The combining of the outputs from
two capacitively and magnetically separated devices.

Hi Ivo,

I have played with this "toy" a little and I must conclude that in this phase it is nothing other as a step-up dc-dc buck converter. Nice work indeed! The negative back EMF is used to create a high voltage level, but it means no added (extra) energy but only conversion with about 70-80% as I measured. There must be some other tricks to achieve the desired COP>1.

As you read it already:
"Now we cannot push power and take it at same time, the trick is only this. Then for a resonant circuit, we charge the capacitor and it discharge into his coil. Trick is to discharge the capacitor when he reach his full voltage and power the load, charge and discharge cycle, give take exchange in balance... Also power can be extracted by differential output coil, this mean half is CW and other is CCW, source in the middle. One side is grounded and other side is connected to a capacitor. The primary can be moved to tune the system to get the best COP."

So, I suspect we need to construct another switching circuit to replacing of the output spark gap!

Another consideration is to calculate with the wave impedances of the coils, namely the lenght of the coil wires to avoid unwanted wave reflections. It can be necessary to apply an isolated litz wire (all thinny wires extra isolated in the cable) to avoid the skin-effect at higher frequencies, but it is a detail to increase efficiency farther. 

I hope I could help you! Keep going on! ;)

There is. But you must first start thinking in terms of intensity rather than quantity.

NdaCluuDzzz! Can you tell a little more about your ideas? Fast impulses are a key to success, but what else, what do you think?

https://en.wikipedia.org/wiki/Betatron



"A common misunderstanding is that (a) the quanta of the fields act in the same manner as (b) the charged particles, such as electrons, that generate the fields. In our everyday world, electrons travel slowly through conductors with a drift velocity of a fraction of a centimeter (or inch) per second and through a vacuum tube at speeds of around 1 thousand km/s,[9] but fields propagate at the speed of light, approximately 300 thousand kilometers (or 186 thousand miles) a second. The speed ratio between charged particles in a conductor and field quanta is on the order of one to a million. Maxwell's equations relate (a) the presence and movement of charged particles with (b) the generation of fields. Those fields can then affect the force on, and can then move other slowly moving charged particles. Charged particles can move at relativistic speeds nearing field propagation speeds, but, as Albert Einstein showed[citation needed], this requires enormous field energies, which are not present in our everyday experiences with electricity, magnetism, matter, and time and space"  https://en.wikipedia.org/wiki/Electromagnetic_field

These kinds of devices generally operate at 1000v as a minimum and go up from there hence the reason they use a HV supply. For most experiments I use a 20kV source but have also used a Tesla coil running over 300kV.
