The project for today is making the Biggest Giant Diode in the World with a Peak Ampere rating of upto 20,000 Amps and a maximum handling voltage of upto 400V.
This project has never been made on RU-vid which thereby makes it one of the best diy project of 2020.
Its continuous current handling capability is upto 300A.
For making it, i have used 50 small 6A diode connected in parallel to reach upto 300A continuous rating.

Все диоды имеют немного разные характеристики, поэтому каждому диоду нужен резистор 0.1-0.3 ом, иначе некоторые диоды пропускают ток в несколько раз больше чем другие, они сгорят первые, а затем на остальных ток увеличится.

@acodonicking6107 3 года назад

Правильно, но ему все равно. Ему и на площядь контакта, и на проводимость олова, и на нагрев, и на крепление выводов все равно. Главное один раз покозать и денюшка придёт. Но спасибо что ты объяснил особиность диодов тем кто в этом не разбирается.

@altfurr7276 3 года назад

You are great channel, but be careful with semiconductors in parallel. if they are not from same batch(trust me, they are not), they will have slightly different values, so trough the weakest diode, current will flow and burn it. after that it will switch to another weakest and cycle repeats. but i like your ideas! Greetings from russia!

@Rk76742 3 года назад

This is exactly what happened when i used two 6amp diode in parallel to run 8amp of load. After 2-3hr the diodes were melted.

@insylem 2 года назад

Ok, I have 2 Questions about this: 1: How is the inductive flyback effect being handled from the motor? I do not see a huge spark when you break the contact. Only when you make it. 2: How are you getting the Diodes to share the load as equally as possible. Each of those diodes, due to the limitations in manufacturing, will have a slightly different forward voltage drop. This would cause the diode(s) with the lower voltage drops, to take on much more current than the ones with the higher ones, in turn may cause them to fail sooner from having too much current through them, while the diodes with the slightly higher voltage drops, are still turned off due to insufficent voltage to turn them fully on.

@melonmusk7502 Год назад

The inductive kickback wasn't much at all. That big blue capacitor is responsible for the spark when he connect the terminals together. Regarding the diodes however, all of them are probably from the same batch. Even then, its pretty likely that the vast majority of the diodes are inactive and all the load is shared by 2 or 3 diodes with the exact same characteristics

@nikolaishriver7922 3 года назад

Pretty cool, next time I would just solder all of the diodes together on the inside before doing the outside. That would make the connections a lot easier to do in between the diodes

@mattweger437 2 года назад

@redeye619 2 года назад

So did I at first, many things could have been done so much better with this, should have soldered all the diodes together before making the groups for a start, should have if going down the track he did, worked his way out at the same time with the copper wire so it actually makes a good connection with every diode pair, when putting it in the can as he did he should have potted it in mineral oil so that less chance of thermal burn up of individual diodes as that would help spread the heat a little more evenly, however those diodes wouldn't be happy under a proper load anyway as the center ones would have little chance to actually dissipate heat, not only that im not sure how much that diode is actually doing considering its already going through a bridge rectifer before it even gets to the homemade,

To be fair if he had a diode tester he could put together a matched bundle, but you'd probably need hundreds if not thousands to sift through to find 50 matched diodes. At that point just buy an actual industrial sized diode. 🤷

Instead of using bolt to end connection you must use heavy copper wire for good electric conduction. Nut using in this project might be voltage drop. 😊

Диоды надо запаивать на радиатор из жести или меди, чтобы по выводам от них отводилось тепло, а такая поделка на термическом клее приведёт к сильному перегреву диодов внутри сборки и выходу их из строя, ток через оставшиеся увеличится и они тоже сгорят.

Young man, I do appreciate your knowledge of Electronics. You put out very well made video's. But the work you've done here in this video is very sloppy and really un-professional in my opinion. Some young person going to try this and get killed. This Diode you've just created could have been built better and you know it. This is very un-safe. Just saying. I'm not going to rate this video because of the Danger of the component. Not saying you didn't do a great job, because you did. The Diodes should have been welded. Not soldered. Shouldn't have used the Aluminum Can at all and you sure didn't need the Copper Wire. You should re-design this product for Safety and Durability. Just my opinion. Thanks for the upload.

Your soldering iron tip is coated in oxide. You must use a wet sponge soaked in water to remove the oxide. Then you can coat the soldering tip with solder which is called conditioning. If you do not do this, you will waste a lot of solder and it will not get hot enough to flow the solder.

The second looked like an universal motor from some kind of a compressor. The third motor is an electric starter motor from a 100 to 150cc motorcycle. If you are considering making an electric vehicle, please consider a bldc motor. They are slightly more efficient compared to brushed motors.

Avoid the maximum power curve suplied by the semiconductor manufacturer.

@alanpartridge2140 2 года назад

@juan carlos quintana No Juan it is not possible. As diodes and semiconductors heat up their resistance decreases, this allows more current flow heating it up more, decreasing resistance etc..... The current rating of parallel diodes is equal to the lowest current rating of any of the diodes. The only time they might be in series is for safety critical circuitry but in which case both will be rated for the maximum current. Were the diodes in the power supply part of a rectification stage? Or were they feeding separate components
