I've always wondered if building a capacitor bank out of regular small electrolyte capacitors was worth the effort. Since they are so common, you can get decent bulk discounts on them which is a big plus. Thank you for confirming that indeed expensive caps are not a requirement for a useful (and scary) capacitor bank 🙂

Why not breaking the capacitor array into 3 seagments and switch each seagment after it discharged that way you will cut the huge amperage by 3 and will increase the duration of the weld by 3

Your lead inductance connecting the capacitor bank to your welder and the lead inductance of the wire leads for the welder itself are limiting the peak current. Use a beefy coaxial cable (RG-8U) or at-least twist your leads (form a twisted pair tx-line) to reduce the series inductance.

@@jacobp.2024 If they're correct then it's good advice. If they're wrong then it can't hurt. You can never go wrong with larger cables when carrying current, especially in a situation like this. However, smaller cables can get you in trouble, especially in certain situations where they might melt and cause a fire due to overload.

I still own a fanastic MIG/MAG welder from the German company ESS. They used large capacitor banks in an assembly of many small ones in parallel. The welding result was very good, this cap bundle gave a nice punch at the beginning with full current.

Very much looking forward to the video where you use the film capacitors for induction heating!

At school I could reliably hit a man sized target with capacitor goo and the cardboard cap from around 20 yards using a regulation 470 uF electrolytic cap charged to 48 volts reverse biased. It shouldnt take much to make a circuit that uses a push-button to simultaneously cycle power through 500 of these caps lined up one by one, and energise a relay that pumps 48 volts through the currently 'selected' cap the wrong way. That way, you have a 500-shot machine gun ;) Even better, use a 555 timer to create the delay between 'shots', and set it up so once the 500th cap is fired, the 501st 'shot' is fired through the 555 chip itself - making the chip the 501'st 'bullet'! - 555 chips themselves make great weapons.

470uF and 16V we use in a Half-Bridge inverters 12V to 230V and more if you gonna use pure sine on the output even with EGS002 ;). Electronoobs has this inverter in his YT channel, I'm building it now and have videos in general about it. Will be more as well.

Just out of curiosity how did you connect the leads off the capacitor bus, was it on the same end for the + and the -? Meaning, if you have a row of 500 caps with a + bus on one side and the - bus on the other side, where did you put the terminal connections? On the same end of of the bus for both + & -? For example if the Left side of the bus starts with capacitor 1 & the far right side of the line /bus bars is capacitor 500 (and all caps are spanning the +&- bus bars), where are the terminal connections for the bus? Are they both on the same end, either near cap 1 or near cap 500? Or did you put it in the middle? I was told that for a large cap bank the best option to get the full working value of all the caps & to deal with any ESR resistance is to put a terminal (just for example) on either the + or - bus next to cap 1 & then the other terminal connection on the opposite bus next to cap 500, so you will have terminal connections on opposite sides of the capacitor line/bus. IDK exactly why, much more knowledgeable people in electronics agreed that my setup (of 80-100 caps) would be much more efficient this way & probably get much more power out of it (but they weren't all identical caps nor all new). I'd be interested to see if there is a difference if you have the connections at opposite ends of the bus b/c if they are connected on one side, you may only use the first 50 or 100 caps at full capacity over & over, where if the other way, (I was told at least), you will use the same total energy but it will be spread out over EVERY cap. I hope this makes sense.

You can clearly see in the video how everything is connected. He has 20 buss bars connecting the boards together. He has a pair of conductors going from each board (6 total) from the center of each buss to the welder. Two cables in the middle or one from each end will give you about the same results. Connecting them all at one end would be worse.

That LiPo battery pack is not rated for current in "Celsius". C stands for the capacity of the battery. A current rating of 30C means it could output 30 times is capacity in current. That might sound like a word salad, so let's consider the example. The bettery you have is 5300 mAh (if I remember right), and was rated for 30C discharge current. If it were 1C, that means you can output 5.3 amps. If it were rated 10 C, it could output 53 amps. And 30C means it can output 159 amps. Usually these kinds of batteries have different ratings for discharge current and charge current. It may be able to discharge 30C but can probably only charge at 2C to maybe 5C.

Ultimate device killer

A charge pump would be also very intrresting but I am unsure if you would need bipolar capacitors

@scienceandmathHandle

2 жыл бұрын

In most cases you would not(unless you expected ringing) as a charge pump always charges in the same direction, and discharges similarly. They effectively charge in parallel and discharge in series for a boost, or charge in series and discharge in parallel for a reduction. Its slightly different for a negative voltage charge pump but effectively its the same thing, just charging from positive to ground, and discharging from ground to negative. I've been thinking about charge pumps a lot lately lol! You could even make charge pumps with variable capacitance values to vary the voltage from fixed N multiplications and dividers to different value capacitors for finer voltage control up and down. Or vary different numbers of fixed values in series and parallel for different control schemes. But it will never be truly isolated as a lot of capacitors fail into shorts.... so transformers are still the way to go, in that regard.

We're having a chip shortage and here you go, having tons of chips. Sell them now and you can make millions.

25,000A? I don't think your current measurement is accurate... 3 of these FETs already have 0.6mOhm of ON resistance. Also these FETs can handle maybe maximum 4kA for 1ms.

The capacitors are 32 joules 16v,so 2 ampere in 1s,which is 2000a in 1 millisecond, 600a avarage in his three milliseconds of short circuit weld time. But I wonder if you got low resistance for example doing the weld directly from the capacitors with a large relay, if it would reach 25ka for lower than 0.1 milliseconds. But surely you can't spot weld with that even with high pressure the weld time is too short?

@Astri.electronics

2 жыл бұрын

Same thought here, those small FETs would desaturate way before reaching few thousand Amps. Not the mention that at 16V, 25kA would mean a total resistance of 64µΩ, just his current shunt has a higher resistance. Maybe he setup his probe to x10 while it was on x1, common mistake. 2500A would be much more plausible but still quite a lot. I would expect something like few hundreds of Amps.

C is the ratio of discharge current to capacity. It would have unit of ampere to amp hour. A 3 Ah battery rated at 10 C can be discharged at 30 A. Conventionally, fast charging is usually 1 C and slow charging generally happen at 0.1 C.

hmmm... Nice video. Suppose that someone worked with a capacitor manufacturer and had access to tens of thousands if not hundreds of thousands of C0G power conversion MLCCs with voltages in the 200V to 15,000V range. What would be the most optimum setup to try something similar with a large bank in terms of peak current? Obviously the power density would be quite a bit lower but the resistance would be too. I am guessing that minimizing the path length to the electrodes would also be massively important to take advantage of the lower internal resistance. Also ringing would be an option for a larger integration time in terms of welding over polarized caps. Just curious... for a friend.

Using a giant amount of components would lead to other disadvantages. The track resistance and inductance would limit the current delivery. Also you would have to inustrially assemble those banks. And how would you repair it in case one of the MLCCs fails shorted, which they sometimes do?

Even here stuff is hard to find at times. 18 month wait for some new cars (not exotics - normal cars!!)!? Over a year for a set of tires (specific ones mind you). Some stuff is 300-600% higher than it was in Jan 2020 if it's even available. There are a lot of people hoarding - people who can still buy at old contracted prices (pre "plandemic") and then sell little by little for huge profits. There's some stuff that used to be ~1-2 cents each & were selling for 15-30 cents b/c people needed/wanted them (usually sold 1000 or 5000 at a time). Then there's the jobs & minimum wage which is still the same ($7.55/hr federally). Many employers haven't increased pay at all during this even though they can't find workers.
