Hello, I have extensive experience in analog and digital electronics, electrical circuit modeling in LTSPICE and TINA...... Now I am facing a problem which cannot be solved using the above software. I need to build an LC excitation and wave resonance circuit in one coil. For this task I am looking for suitable simulation software. I would be grateful if you or a technical expert could help me.

 

I need to build an LC excitation and wave resonance circuit in one coil.

You need to be more specific about what you want that circuit to do if you expect any pertinent help as " LC excitation and wave resonance" tells us little.

 

The outcome of light projectors on water ripple tank was first. A projection showed rarefaction and compression.
When boundry conditions of an inductor in an RCL circuit are defined a comsol can be rendered for various media.
There are renderings of ideal waves with constructive patterns.
The oscilloscope and spectrum analyzers give us practical information as sensed for a specific inductor with given boundry conditions.

When you say "boundary conditions" do you mean the boundaries of the circuit itself or of the space the electromagnetic waves around the inductor take up?
Or is it just the initial conditions?

I have a feeling you are talking about the entire space the RLC circuit takes up, like the 3d dimensions.

 

Вам нужно быть более конкретным в отношении того, что вы хотите от этой схемы, если вы ожидаете какой-либо соответствующей помощи, поскольку «LC-возбуждение и волновой резонанс» мало что нам говорят.

I would like to combine the LC resonance of the circuit in the LC oscillatory circuit with the wave resonance in the coil of the circuit. I would like to find a program in which this could be simulated, if one exists, and then build a resonant system. I would be grateful if anyone can help with advice.

I am sorry but that is still not a clear enough description.
Perhaps you can make a drawing.

What is this going to be used for? Could it be for a wireless charging system? Just guesses until you make the purpose more clear.

I am sorry too, but I do not understand what is not clear here... I suppose my English is not good enough. I mean a LC oscillator where resonant frequency exists in according to values of L and C. In addition a wave resonance in the coil is required. This resonance defined by the length of the coil wire, for example 1/4 or 1/2 of the length of the wave resonance. Concerning the purpose, I cannot spread it because I have signed NDA agreement. I can only tell that Q (goodness of circuit) will be very much increased in this system.

Does the organisation that had you sign the NDA know how it works? I bet it's something to do with free energy!

I won't comment on your assumption. I'm looking for an answer to my question. You can help?

Hi,

Well the point of confusion is where you say you want LC resonance but *also* resonance in the coil.
The key word here is *also* because if you have resonance in LC then the coil is already partly responsible for that.
So if you have resonance in the LC circuit then L already takes a part in that and if you change L you change the frequency.
So that's the main thing, why you are specifying the 'coil' apart from the LC resonance. You'd have to explain that in more detail. You should be able to do that without revealing what the application is.

This is why I was suggesting this might be for a wireless charger, because there is more attention to the coil than the capacitor because the coil has to radiate the magnetic field in a reasonable direction, and you seemed to be placing more importance on the coil. That was just a guess of course, and you don't have to reveal the application. You will have to find a way to explain this better though, especially the added attention to the coil.

If you are talking about the physical construction of the coil then that's a different problem. You can find coil winding formulas on the web. Because the physical construction determines the inductance, and the inductance L works with the resonance w=sqrt(1/LC), you need to know how many turns and wire diameter and coil diameter and length of the winding, which would be part of the construction of the coil itself. You also have to bench test it because the formulas are not usually perfect and slight differences in winding can affect the inductance. This could require adding or removing more turns, or spreading out the windings slightly, or some other adjustment like to the metal core if you use one; a change in position, a change in material, etc.

 

Hello,

Thanks for your insightful response.

What I mean is this. Let's take an example. We have an LC circuit with a resonant frequency of 5 MHz. For this frequency, 15 m is the wavelength. To obtain one wave resonance in the coil, the length of the coil wire must be 15 m. For 1/4 wave resonance - 15m/4, etc.

We can change the values of L and C while maintaining the frequency and length of the coil wire - the wave resonance conditions will remain the same.

Regarding the calculation of the coil and its manufacture, this is a separate task, also a bench test.

Now first of all I am looking for a way to simulate the process in order to understand the features.

I need to correct my mistake. For 5MHz 60m is a wave length, 15m for 1/4 wave resonance

 

RE:"" I need to build an LC excitation and wave resonance circuit in one coil ""
Similar task is everyday effort for those building an Tesla Coils as well the Mishin`s coils. In their forums are plethora of formulas how to pass both frequencies. Or adjust it practically, when frequency is optimized by CD4046 take some wounds more or less of that had been calculated amd measure the Voltage.

Hello, I know everything you mentioned. My challenge is to find software to model both resonances. Do you have information about such software?

 

Hello again,

So you are saying you want to change both L *and* C in order to keep the resonant frequency the same?
Since L and C are related (in simple terms):
w=sqrt(1/LC)
when you increase L you have to decrease C, and vice versa (L and C are symmetrical in that formula).
When you change the physical construction of L you change the inductance unless you wind it in a different way.
There are a lot of ways to wind a coil. All one layer, two layers, N layers. Coil form 1/8 inch 1/4 inch, 1 inch, 10 inches, etc. Core material could be air or some magnetically active metal, or several types of composite core materials.

I do not know of any software at the moment that would simulate the inductor based on the actual real-life windings and other physical attributes. You should be able to calculate this though as an estimate, and then you can play with the dimensions to see what you get when you change something. That can help guide you to a solution, then bench test it for verification and/or adjustment.
