I don't know whether I missed it, but you should mention that these charged capacitors could be deadly to people due to the large amount of energy stored in them. Please be careful not to touch the contacts.

I built the same ZVS driver circuit a few years ago and it worked extremely well. I got some nice fat hot orange arcs on my jacobs ladder that I built. It also worked very well with the induction heater too.

the idea of ​​the high spark instead of the hub is a great idea. One that doesn't hold the button, but the other estr that is even quieter ... at what explosion it makes, the sound is very strong ... Anyway, your videos helped me a lot to understand some theories ...

I built this driver circuit many years ago and it is perfect for a jacobs ladder. Nice thick red fiery arcs like you see at power station short circuits. Used it with 2 x 12V car batteries in series. 24V

Damn, that thing can be quite deadly actually (the charger as well as the charged capacitors).

Sir your explanation is so simple any one can understand thank lot

Hi Ludic the output from, ZVS is a sign wave so you don't need an air gap in the core you only need a gap if its being driven single ended (flyback) that is where the transistor turns on and the core is magnetised the core stores the energy and only transfers it to the secondary when the transistor turns off in a flyback topology power supply the output rectifier diodes are reverse biased when the transistor is on and forward (conducting) when its off that is why its called a fly back excellent vids thank you keep up the good work Steve

I noticed you connected diodes in series to - I believe - increase reverse voltage. This simple configuration has a drawback: any mismatch of reverse current will cause uneven distribution of reverse voltage which may cause cascading failure. Normally an equalizing resistors are added parallel to diodes.

Also made an induction heater with it and it worked very well.

Be nice with a built in analog volt meter. Be good to see the cap discharge too

Great but please make additional video for how to safely remove the charged capacitors and connect them to another circuit

good and informative

Very interesting, especially your high voltage bridge rectifier.

Hello LS, Can you please explain why the transformer winding requires isolation between layers? I thought magnet wire is already isolated with enamel. Thanks.

It would be nice to use a resistive divider and feed a small sample of the output voltage into a comarator so you could make it automatic just set max voltage and use a fet to drive a normally closed relay (that way should the fet fail short it would be stuck switched off) have the relay break the Vcc to the ZVS

I have a question to ask, for 48v, 3Kw DC motor I wanna make a backup capacitors pack, when I switch from one line of electricity to another, in that moment I need capacitance for few seconds,I don’t want to stop motor during switching, for that purpose how many caps, how many capacitors in pack required?

Could you go over how you calculated the turns you needed for the transformer?

nice circuit ! can we test capacitor leakage current using ammeter? with this circuit

Danger mr Robinson

I have a big doubt, could make a video about my question, which is: Every receiver is also actually a transmitter, but of lower intensity (power) than the actual transmitter itself ??? Explaining: Whether in the transmitter and the receiver, we know that each one uses its own tank circuit (in inductor and capacitor configuration). So I believe that regardless of the signal, I mean when it comes to the carrier wave, we know that a RECEIVER also uses, in its electronic scheme, the tank circuit (coil and capacitor) to oscillate and thereby suck in resonance. frequency of adjustment by the frequency characteristics of the emitted transmitting wave. And that's where my doubt comes in: I think the RECEIVER should also transmit waves because of the tank circuit, but with low power. Thus there would be the resonance meeting between transmitter and receiver, in which there will already be in the path between the two, as an example, a mechanical system of a balance: Where the person who pushes with his arms (would be the transmitter) and the swing itself (would be the receiver) and both need to be in sync with the commuting, let's say, so that there is resonance and with that there will be signal absorption by the receiver, and then a transistor on the receiver output amplifies so that the power is audible. I hope I could explain it well. I would love to know if this is what happens ??? If you understand me. Grateful I await a return.

Why not just use the flyback that you took the core from. Than all you need is a light ballast to power it

i was expecting you that you will discharge the capacitor with screwdriver and show us big sparks❇❇⚡⚡

Will this work if I use 3v batteries? Or does it only works with ac power? (How do I charge capacitors with dc power and transformer?)

Did you have some fun discharging the capacitor? Should have included that in the video.

My coil was also home made and had 850 turns.

where can buy capacitor?

I could hear a high pitch sound while you charged the capacitor. What is that?

Can you let us know the max current seen when you began charging the 450 volt capacitor?

this is so good, thanks!

Its not ludic science its lunatic science 🤪

I have 100uf 400v capacitors and I would like them to charge faster. Do you think that if I put a multiplier at the output of the high voltage transformer, do you think it will charge faster? the joke is made 3 capacitors in series after which I have 4 rows placed in parallel ... I would like it to charge much faster so I ask you ...

The diode you used is 1N4007. These diodes are not applicable in high frequency applications. So how the diodes did not get damage and malfunction ??

I am thinking of coil gun. 1/2mv^2= 1/2CV^2.

couldent understand what gauge he said the transformer was

If you want to you watched and understood need to sometimes write some figures. Do you want to be understood by everyone?

That is all old. Been done in all CRTs, all TVs Tube monitors. They had 40 to 50 kv. Nobody died from them. All you have is puny little Hv supply!

I also made my own PC board which looks much better than your one from JLB. Better design.

You have an accent.
