Can explain why this gets more than 10 kv from 220v source?

Thats nothing unusual when using this particular components in circuit having parameters such as u have voltage will boost up to 10 kV even in real circuit

The problem is that 400 uF non polar cap designed to operate under 400v AC is big as typical 20 litre beer barrel. And 10uF caps capable to store 10KV !! Do not exist as single element but as large batterys serving its role in research labs that deal with ultra high power pulse discharges (to levitate a frog for example lol XD)

Its bcoz of the inductors...its preserving the energy then releasing it through capacitor..

Nice explanation @Secuture

The frog levitation experiment. It requires a superconductor doesn't it? High lossless voltage plus superconducting equals some very disturbing effects. For instance the cold itself, below a certain point makes fluids to pass through solid objects. Extremely low temperaturea plus certain conductors make ohm's law invalid. I mean the theoretical resiatance of a superconductor is exactly 0ohm. So I=U/R doesn't apply since you can't divide by zero. I've drifted a little off topic but i find superconducting experiments fascinating.

Most interesting fact about superconductors and superfluids is fact that achieving absolute ideality in our funny universe is not a nonachievable limit that can only allow to get close to it but never reach. For superluids a low temperature make particles loose its capabilities making them more and more primitive as at some point they became so primitivized in capabilities due to lack of energy for any more complex behavior that "having viscosity" feature as very complex thing became far beyond their powers and ideality is born

Yes i haven't thought of it this way but it sorta idealises the universe. We all know the laws of thermodynamics where they say that you can't sustain a process without inputting some external force to keep it from decaying. Everywhere you look you'll see this law in motion. From mechanics to electronics to even biology. The fun starts when these rules start breaking down under low temperatures. For instance if you remove the R from ohma equation the law takes this form. I=U. This means that as long as you can keep the conductor in superconducting state the current inside of it will be kept in a constant loop, never fading. I wonder if that has any application in resonant circuits and in radio technology? Any ideas?

Tank circuits in radio technology do not suffer from high resistance. The resistance is at several MHz extremely low and results in high Q tanks. Its even the case that it needs additional resistance instead, to get a proper bandwidth. In GHz technologies the Q can easily reach Q bigger than 1000! And all this at environment temperature >20degree celsius ;p

That's not what i meant. I'm not sure if the conductor will expell any magnetic field but since the current is always looping in it there wont be a need for oscillator circuits just a one time propelled tank circuit that will continue oscillating without external influence. Of course it cannot be tapped but the mere presence of the phenomenon causes some weird effects like levitation and such. As Secuture said it's very weird that all laws of physics seem to fail under superconductivity.

Maybe this can power an antigravity device

But the "it seems" is the key. At a temperature of a few kelvin some materials, such as lead, become superconducting and here starts to get strange, the most likely hypothesis that superconductors do not seem to follow the normal laws of physics is why these laws, maybe are incomplete . The same thing happens at temperatures near the plank's temperature, approximately 1.41 * 10 ^ 32K

So.. This circuit can works in real life?

If you get the appropriate components, I think yes

Add a load to the output and see what happens.

@headshoter, check what you can get as 1H coil. I guess at least 100Ohm resistance is minimum. In your simulation you have 0 Ohm inductor which is only possible with superconducting material.

@hurz Nice explanation dude

Don't superconductors expell all magnetic fields? I mean won't it act more like a superconductor than a supercoil?
WTFCircuit

I made myself a 1H inductor using a microwave oven transformer core and it has a dc resistance of 32.5 ohm. thebugger, yes superconductors expel magnetic fields and that is why they create so strong magnetic field, it is completely to the center of the core and not around the wires or inside a ferrite core

WTF is just joking as usual he tries to start a charade again. But even with 30Ohm this circuit here would generate ~500V and not 10000V.

As far as i know superconductivity breaks the skin effect thus not generating magnetic field itself. I think you'd need a ferromagnetic material to induce magnetic fields with superconductors.
WTFCircuit

You don't need a ferromagnetic material for a superconductor because the core will lose its property of enhance the magnetic field at this power. A ferrite core is usable until the density of the magnetic field reaches the 2 teslas limit, then it is completely useless. And this time this is not a charade, hurz I'm serious.

MRI's still use highly magnetic toroidal cores to induce the extremely powerful magnetic field. They're not ferromagnetic because they are not comprised of ferrum but the rule still stands.

I was talking for a ferromagnetic core, not for other tipe of it...
