120,000-Volt Multiplier

This video shows how to build a cockroft-walton type voltage multiplier using a flyback transformer as a first stage driven by a ZVS driver with a 12V input. This circuit outputs 120,000 volts DC and arcs from ~4" away. Within about 2 feet of the device, you can feel the ion wind, and your hair being pulled toward it by electrostatic induction.
I didn't use any current limiting resistors, so the discharges are very dramatic but also extremely hard on the capacitors in the multiplier. After about 4-5 seconds of continuous discharge, there's little to no output, and the device needs a minute or two to recover before it can be used again. My guess being that the caps are swelling under such a high load.
The flyback and ZVS driver are both homemade. The circuit for the ZVS driver is explained in more detail in my video on induction heating :

    I made a flyback transformer myself so I know how hard it is to get it just right and then you have to prevent arcing to itself, I potted my transformer in candle wax, the layers between the coils that I wound on top of each other instead of what you did having the coils next to each other I used paper for that so it helps getting the candle wax in between the coils since it will wick the candle wax up which worked out very well for me, I had to use hot candle wax to get it in between the layers and then let it cool down to find a hole exactly where the coil was located. I filled it up with more candle wax and I also put in the capacitor bank and the inductor in the same plastic container filled with the candle wax to have all of the high voltage parts nicely isolated in a plastic can or box. Since I've made that flyback coil myself I haven't blown up any more mosfets, and I can leave it on for a very long time without anything heating up so I'm pretty proud of my hand made construction.

Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God. It reminds us that since God created us, no one should be worshipped except God alone. It also teaches that God is nothing like a human being or like anything that we can imagine. The concept of God is summarized in the Quran as: { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4) Becoming a Muslim is not turning your back to Jesus.

    Nice! You might even be able to add a wire brush drill (or something similar) at the end for increasing the amount of points to generate more ionic wind. Some of those brushes might even be able to be screwed on (with an adapter) the tip. If you put a PVC pipe over that (with air holes below the brush) the ionic wind flow going straight up should be even more impressive, I think?

My "X-ray vision" doesn't work so well on videos to see how the lamp base was wired, or if you just wound it to the post with foil and caused a short? Also, I've never seen anyone try that with an incandescent lamp either, only seen people use fluorescent tubes, so maybe that had something to do with it?

    @@HyperspacePirate Good. But the diode drop is negligible, even for high voltage diodes. The capacitors in my experience are more likely to cause some meaningful drop, about 2 kilo-ohms impedance per capacitor at 80 kHz. If I counted right, you have 12 capacitors (as well as 12 diodes) in seres. That means some 23 kilo-ohms total impedance. The voltage drop of course depends on current as well as the impedance, so I don't try to estimate that. Nor do I know the AWG36 winding length, but you have there about 1.3 ohms per meter, just for pure resistance. On 50 or 60 Hz AC between 0.5 meter spheres and 1 cm gap, you are supposed to get sparking to start at 30 kV RMS. In the old days that was actually used as a measuring device. Anyway, the spark initiation voltage depends on the electrode size and between a point and plane or two points, you get considerably lower initiation voltages. You notice, how close you bring the ground side wire end before the arc starts. After the start, maintaining even very long arcs is easy due to existing ionization. All this is why I am curious about your actual voltage. Once, when Heathkit was still around, I built their 40 kV probe and quite recently I built two DMM voltage extenders, 10 : 1 dividers with 1% high voltage (15 kV rated) resistors. I also contemplated buying some vintage electrostatic HV meters offered at eBay, but ended up not going that way. Well, good luck in the future with your experiments!

    1MV is quite difficult. Things start to get tricky when you get into hundreds of kilovolts. Starting with a low voltage and using many multiplier stages makes no sense. You would be better off starting with something like a 150kV transformer. Those things can get big and expensive quickly. 1MV is probably more doable with Tesla transformers or static generators.

    There are many types of oils. As a hobbyist just use some mineral oil you got on hand. It's usually not worth it to buy special insulation oil like Shell Diala. You can use silicone fluids and even ricinus oil (not recommended for hobbyist). There are also insulation oils derived from seed oils. High Performance oils can be made from natural gas (gas to liquid). Beware of old transformer oil. It can be highly toxic.
