Use No 40 wire with 11% more space between core and base of winding. Reduce Space between individual windings by 35% and you will get 25% more sets of windings and 60% more turns onto the configuration. This will provide output of more voltage with less driver current.
Adding 60% more wire whilst reducing insulative material between coils is a terrible idea. This works great if using a diode stack (one in between each coil) for DC output. The problem is HF AC eats/degrades insulation over time. Many 3d printing materials also suffer large losses and heat considerably from HF AC.
I don't have access to a 3d printer but im an engineer with lathe access so im going to make a bobbin based on your design from solid stock nylon. really like your design and have a load of flybacks from old tvs that i have stripped but as with you, i need HV AC not DC for many of my projects so your design is mint.
nice one! I have a question. How do take the wire from one section to another section? I see there are slots accross the section. the last turn of a section has higher voltage than the first turn of the section. When we take the last turn of one section to first turn / layer of the next section, there will be large voltage differences. Does it not cause arcing through copper wire insulation?
This is a key concern when winding such transformers. You have two options. The first being to estimate/roughly calculate the peak voltage potential between each pancake coil/spacing and then submerse the transformer in oil and/or add a sheath onto the transfer wire heading into the next section. The second option (more ideal) is to have a hole and "tube" leading to the BOTTOM of every division allowing the HT wire to start at the bottom of each division thus greatly reducing arc over and wire to wire potential.
It makes it so that in 1 slot the voltage between the winding with the lowest potentential and the highest one doesnt get too high and arc. It divides the high voltage into multiple lower voltage parts.
Really cool, im going to try this, I dont have a 3D printer, but i have a lathe I will just turn a similar piece and mill out the slots in the plastic. I’m thinking of just using a simple 40amp DC PWM speed controller to control the frequency for now. It doesn’t have to be super precise. I have a few projects I need some REALLY high voltage for. Thank you for this video and construction techniques
Hey, You will burn out your transformer like that, I'd recommend putting it in a transformer oil bath. Then you can drive it even harder. If you look closely your transformer is turning blue when its on (arcing across)
Its ferrite. Its used instead of an iron core like in a "classic" transformer. It works best at high frequencies (in kHz to Mhz range), so you always need a driver circuit (ZVS, royer) to power a ferrite core transformer.
Hello can You help me ? I want to make HV transformer for ozone generator. I have Chinaise ozone plates with parameters 5kV 80W can You give me details for wires diameters etc, trigger ?
yes oil is great insulator and cools the transformer as well just got let it touch any thing giving off electricity. Is seen pwople cover these transformer in hot glue thebun a glass jar of oil
hello, I am looking to brute force myself to high voltages with no driving circuits. I am looking to re-wind a MOT transformer for 30000 volts at 30mA (900W). Will 32 gauge wire work? I estimated I will need 32000 turns. I will rectify the AC to DC and use a Variac for power control. I want to re-use my primary coil. I do not like using driving circuits and such and need the ability to swap between negative and positive output.
It would be easier to use a voltage multiplier to get to that kind of voltage. Start out with 3000v and do 10 or 11 stages. The down side is you won't have that level of current. 30ma could potentially be lethal. I'd try to keep it under 2.5ma or even get it in the uA range. If you just want impressive arcs try a Marx generator.
you have to multiple High voltage diodes, between sections or else if you are planning below 15kv then one 15kv diode is enough. But here dc means one direction not ripple free, but that works for every physics research needs from xray to ion beam.
It depends on the transformer core specs. If the core can handle 350Khz, then it sure would (coil numbers/layers differ vastly with different frequencies however).
Well most people have heard of Arduino and can possibly get or use a 3D-printer. If you don't have the tools, then you can't expect to do everything you want to. Not saying it's necessary for this kind of project, but in many cases you can't blame anyone with the right tools for you not having the right tools x)
Bogdan Rotaru There are a lot of 3D printer kits available now for really cheap. They are easy to assemble and use with enough research on them. I got my first one when I was 15 years old for $200 and it was easy enough to assemble.
Are you serious? I think using arduino would be easier for someone who don’t have much experience with building circuits. The case can be made from any other material. And don’t forget that you can get those cheap zvs drivers on eBay. People say they work well.

How to get thin copper please tell me😢😢😢😢😢😢😢😢😢😢
please show how to build driver to control frequency
These high voltage transformers are like magic in how it can turn low voltage into high voltage,really impresses me,

What is the purpose of multiple slots on the high voltage winding? Can you share a link where I can read more about the theory? Thanks.

You made a fly back transformer, they're awesome for generating arcs.
does the direction winding relatif to the primary matter in flyback transformer?
Hello Sir, I would like to request how to calculate for these windings? do you have any link to its calculations
The images in the finish of you video it's so Bad

Sir I needed your help to solve my problem regarding this kind of coils
How did you make the herz control? how high can herz be, up to 10-20mhz?
Please tell what is the object shown in time 30:00
sir what is the black material using outside of coil . what is that name and what is the use?
Its ferrite. Its used instead of an iron core like in a "classic" transformer. It works best at high frequencies (in kHz to Mhz range), so you always need a driver circuit (ZVS, royer) to power a ferrite core transformer.
is there transformer can be connected to function generator and step up the voltage to 1 kv at frequency 1khz??
2:25 for you
Hey brother that winding is one direction????????????
yes.

Wouldn't oil work fine instead of resin?

Great video and great device. The link you provided to Instructables leads to copper plating and not instructable for this device. Cheers
whats the model link?
nice guiding
Is this work on mosfit z44 woth 1k ohm regsitance
can this be used for DC high voltage?
No if you use DC no magnetic field no arc
You can use AC
Use the AC POWER SUPPLY
Or you can use DC by multi mosfet transistor
you have to multiple High voltage diodes, between sections or else if you are planning below 15kv then one 15kv diode is enough. But here dc means one direction not ripple free, but that works for every physics research needs from xray to ion beam.
nice job man
Can you post the stl file so I can print this bobbin please sir
Nice work, could you do a video on the arduino driver, thank you.

Does it work at 350 000 hz ?
It depends on the transformer core specs. If the core can handle 350Khz, then it sure would (coil numbers/layers differ vastly with different frequencies however).
