8-10kv

This comment makes no sense on so many levels 1. The secondary is between 800 and 1600 turns 2. The arc gap is around 5 mm and the breakdown voltage of air is ~2-3kV per mm making this circuit 10-20kV depending on humidity and air pressure and the arc gap 3. You then talked about *mains ac* for some reason when the *inverter* circuit runs off 3-7volts *DC* 4. You then used your incorrectly calculated 3750v to assume that the guy is plugging this into the wall and that there is only a 16 turn ratio 5. By the way plugging this into your wall would melt the wires and trip the breaker 6. These basic flyback inverter oscillators generally have a turn ratio of 200-400 with primaries of 5-20 turns and secondaries of 800-2000 turns. They use the high frequency produced through the oscillations of the primary and the feedback coil to automatically adjust themselves close to resonance frequency, boosting the strength significantly. They do not work like traditional iron core 60 hertz wall adaptors and do not need huge turn ratios in the tens of thousands. I don’t know why I wasted my time writing this comment instead of wasting my time playing video games like most other kids would during summer but it kinda pissed me off and I had to inform you.

@@Ferraday ElectroBoom on youtube shows that you need about 15kV to get a spark between a 1cm gap. I judged that the spark was created about 2,5mm between the 2 wires. Take ~15kV * 0,25cm and you get 3750 volts across 2,5mm. I'm aware that humidity changes the result, but here's a video where he tests the voltage gap: kzfaq.info/get/bejne/erV9ppqevtPDqqc.htmlm17s . To me it doesn't look like the secondary side has 800-1600 turns, so i think that's where we don't agree.

3*10^6 V per meter, it is around 30KV. Not 50kv though.

300 windings? There's a lot more than that. There are multiple layers seperated by layers of tape. This circuit is run off of a DC supply. Most likely 9-12 volts and there is inductive spiking on the primary. Its a high powered joule thief circuit.

Thank you for your advice.

dear i need more details for using two transistor

@@TopTechDiy anytime. You could even use a correctly chosen inductor. Classic 6V to Kv supply. 😁

Bro can you upload an video how to attached to transistor

@@TopTechDiy bro, can you make a 1000Kv video tutorial, i want to move this to the stun stick, it can also be used for EMP

Thanks for watching

@@TopTechDiy how many turns in the secondary coil?

andre luiz Most likely the same design a CRT TV Transformer . 🧐🇬🇧🤔👍🏻🤓🤓🤓

yep

fakeee 50 kw flyback transformer is 30 kw and mutch bigger arcs

5 kv max. 1mm = 1kv

Probably is better to Use IRLZ44N

You can use any general purpose BJT that has a reasonably high switching frequency and can carry some current. I made one of these circuits to drive an 8 stage Cockroft-Walton voltage multiplier. The transistor I used was FJP13007H2TU from Digi-Key. It's a 400V, 8A device. The primary current is pulsed on this circuit (in the tens of kilohertz) but it is fairly high so make sure the transistor you use can handle some decent collector current.

And resistor?

Put a variable resistor in series with the primary winding of the transformer.

Nice!

Un poco más arriba alguien describe que el flyback secundario tiene 1000 vueltas y el primario 12 vueltas. Utube no me deja copiarlo . Por favor buscalo en los comentarios.saludos.

No

It's actually like 3,3cm. Electroboom showed that it's roughly 15kV/cm. 50 000 / 15 000 = 3,3cm distance for 50kV

@@FluorescentApe Yes, but it depends on the air moisture. In very dry conditions (under 40% humidity) it's about 15 kV/cm, but in normal conditions like 50-60% air humidity, it gets 10 or less kV/cm. But anyway, the kid claimed it was 50 kV whiich is nonsense, considering the sparks couldn't keep up a distance of 1 cm.

Ahmt Ahmet this circuit oscillates at the kilohertz level and using iron as a core makes it extremely ineffective above 100 hertz to the point where it probably won’t even oscillate

Thanks

There are other videos on youtube that go into more details on how to make these transformers and circuits. This video is not very informative.

Yes, Thank you for watching

@@TopTechDiy love your videos Top Tech keep it coming

Top Tech that gray metal? I was wondering what type of metal is that you make the inverter with don't know the name by chance you know the name?

Wouldn’t have thought so. This is a high voltage low current system, whereas welding machines are mostly high current low voltage.

All of You guys are bad Englich. No just kidding. You can check it by either a gap, or using a hv probe with high frequency DMM (if anything like this exists) or a digital oscilloscope. The invertor is here to create high frequency signal, not sure but most likely DC signal to induce voltage into the secondary coil.

Not everyone knows about 3 kV/mm. You know, and it pleases.

That does not work because the battery can not deliver enough current. Furthermore you need alternating current.

Yes, with an oscilloscope

the arc starts at about 0.2 inch but sustains up to about 0.5". air breakdown starts in this circuit at about 0.2 inch. so that is the number to use. Once it starts the air is ionized and conducts more readily so it sustains itself in a bigger gap. www.cirris.com/learning-center/calculators/50-high-voltage-arc-gap-calculator? the spark starts at about about 0.2 inch. Check .005 inch/1KV = 40KV hypertextbook.com/facts/2000/AliceHong.shtml "dielectric breakdown, occurs in air at an electric field strength of about Emax = 3 × 106 V/m."" = 0.2 * 2.54/100*1e6 = 5000 Volts. So two websites give different results for dielectroc breakdown so the voltage is somewhere in between.

@@johnconrad5487 3*10^6 V per meter, it is around 30KV. Not 50kv though.

The more wraps on the high voltage end means more voltage.

Yeah need one oscillator, fake.

Yes

Yes , we can . Just change the resistor value.

He did not show his battery

@@Its_sachin_7 yes he did he even shows connecting it at 4:33 its pink

Bro it's IRFz44 MOSFET. Yes you need a heatsink for This. A zener diode at Gate will work for safety. And yeah the arch's are 6kv 😅

@@TopTechDiy put this information in description! congratulations to the chanel! sorry my english, i'm from brazil

Top Tech ....Put the component details in the description box .

Transistor d882 npn Resistencia de 1k en la base ...pero eso tiene 5 kv ...no 50 kv

1мм - 1000воль - это а вакууме, на воздухе 3000воль на 1ммм

Пробивная прочность воздуха составляет 3 киловольта на миллиметр

The resistor limits the base current to the transistor. If you don't have it you'll burn up the transistor.

Totalmente lo mismo digo ...1cm serían 5 kv

3*10^6 V per meter, it is around 30KV. Not 50kv though.

Que otro transistor que no sea el d882 puedo usar? O es el unico?

Transistor is IRFZ44N

The resistor is called "Joe mama"
