I'm a welder, and I think after seeing this video, it would be cool for you to make a video with a power supply of this nature, to create a small, portable, welder. Nothing extravagant, just something that could tack together something thin, like 20 gage sheet metal. Either that, or make a battery powered, plasma, soldering iron. Either of those would make my day lol.

The DC versions have the Cockroft-Walton array inside of them, while the AC versions have it outside as a separate unit. It is an interesting voltage multiplier which can be made into any number of stages resulting in multiplying AC voltages (into DC) by any number you want. This device can be used to feed a Marx generator for really high pulse voltages.

The stable purple arc looks more like AC. Normally, with DC high voltage, the arc is irregular and loud. Is it possible the tripler in this high voltage transformer was not working? I made similar high voltage device from compact fluorescent. I let the fluorescent connected as a way to indicate that the circuit is still working. I connect the primary of the CRT high voltage transformer in series with the main inductance of the compact fluorescent.. Doing this, there is no question about overloading any part of the electronic. I like the videos you made (I just found a link today, watched about 5 videos). Contrary to many other youtuber, your projects are working for real. It is not click bait with clever video editing. I would like if you would use the standard 10^3 names for resistances, frequency, etc. For example, 5 kilo ohm instead 5 thousand ohm (or say both if you think it would allow other users to understand better).

@FredtheDorfDorfman19855 жыл бұрын
It's no where near efficient because resonant frequencies of CFL LC tank and flyback don't match. It will drive power through a Flyback but not efficiently like the DC square wave the TV circuit uses that is at the 15 kHz or so flyback resonant frequency, unless it's a computer monitor/small TV flyback which can be 30-45 kHz or more. Most CFL's operate anywhere from 25 kHz up to 100 kHz, but avoid the 32 kHz range so as to not interfere with remote controls.

@FredtheDorfDorfman19855 жыл бұрын
No, if you hook the output of one CFL to the mains input of another you will fry the other, most spectacularly. You can't use them in parallel either. If you want more power go with a higher wattage CFL, or go with a true flyback driver like the ZVS driver. I've used a 55 watt large CFL circuit, equivalent to a 300 watt incandescent lamp, with some good results. An electronic ballast for large straight tube fluorescent lamps puts out a lot of power but only the largest and most robust flybacks can handle it without shorting out internally. If you do go with a more powerful driver please make sure you know what you're doing and be careful.

Nice work. I love the way you explain everything with their proper working science. Bro I've a suggestion for you- If you connect a starter(it was used with old fluorescent ballast that had only two output pins for the tubelighr)in parallel with the primary coil then the output will be 2x higher in terms of voltage. You can use it with flourescent ballast or even with cfl ballast. But I don't know the reason for it's working. If you could please explain it explain it I'll be happy. I have a question- is it necessary that the primary of the flyback has the highest resistance? When I connect the input of the flyback to the first two pins from the right (U) the arc is 1 mm long but when I connect the input to the 1st and 3rd pin from the right then the arc is 1.5cm long. Is it that the primary is the coil between 1st and the 3rd pin from the right?

Hey, isn't CFL-circuit's output also AC so that it can drive transformer? I had a couple problems with setup like this. First, all my CFL circuits could detect if there was a tube attached and worked only if it was. I found that putting a capacitor across a pair of pins attached to the same end of the tube (to heat electrodes?) works fine, and shorting them with alligator clip did the job too. Next, if i play with HV more than few minutes, transformer on a circuit starts getting very hot and then something on the bottom side burns up/explodes (i think some CMD resistor gets damaged by heat). How can i work around the overheating? Maybe a circuit from more powerful bulb would last longer before dying? or was it that i shorted these pins?

Hi Keystone! I have been reading some information about T.T. Brown (Thomas Townsend Brown.). His experiments involved using high voltage 20,000 volts and higher with conductive materials inlaid with non conductive materials (as in metal and wood held together with beeswax in 8 alternated layers) to create a force that caused it to move. Is that actually a thing? Can high voltage create a force that can propel an object? If so. Can you show is how that works? I ask a lot I know. But it sounds so cool! Thanks KS! You're the best!
