At 28 volts you can draw a continuous current of 30 Amps max. For that two diodes in parallel are enough I guess, each one diode can handle upto 30 Amps

Possible to stack outputs and get various voltage levels, could be wired with large boat style battery switches.

[@JJ-kf2uk]

Diodes don't really share current very well (look at their I/V curves). That's why emitter resistors are used to make power transistors share current. The only thing demonstrated here is the performance of one bridge with maybe some partial sharing from another. KBPC3510 bridge rectifier is rated @ 35A and 400A surge which wasn't exceeded by much in the video. I'm pretty sure (8) bridges are loafing. You need some R values to balance things up.

The voltage is higher because after rectification, you are now measuring the peak voltage not RMS 11.3Vac RMS +rectification = 12.6Vdc. Wired at 12Vac you would get between 14-18Vdc. With a bridge voltage drop if 2.2v.

[@johnruscigno5738]

Nice work. Now you just need some balancing resistors between each negative connection. I'd start with 1 ohm, 10 watt and check the temperature of each bridge after a couple minutes of operation and see how it goes. Might need to use 1.5 or 2 ohms.

@samueldavies646 correct. I learned it the hard way while waiting for my big 200 amp bridge to come in the mail. I tried stacking them and they popped like popcorn. It looked as if the current was just passing through the bridge with least resistance until it burst and then going to the next. But we live and learn.

Make way more sense to: 1) Charge a $60 lead acid battery 2) With a small normal transformer-rectifier battery charger 3) Use either an inductive ammeter - or if you need extremely rapid current indication - a heavy shunt and measure the voltage drop across it with an oscilloscope.

[@ЭминатШафоренко]

Огромное падение напряжения гарантировано. Оно суммируется на каждом выпрямителе, что в свою очередь вызовет большой нагрев сборки даже без нагрузки. Конструктивно охлаждаются только выводы диодов. Тепло плохо передается на радиатор, это перегревает внутренние диоды не имеющие прямого контакта с корпусом.

[@johnsmith-000]

Interesting project. But for any of the motors you tried, two rectifiers would be enough. And if you wanted to really utilize all nine bridges @315A you'd need a cable 180mm2 and a much bigger heatsink, maybe another transformer, too. As it is, you can at least be sure you won't overload the bridges easily...

[@chrisowen2925]

I was following along then you changed the colors of the wire when you cross-connected each bank of rectifiers, so not sure why you did that? Red to Black and such... I normally keep a consistent color all Red together for positive all black together for negative, all yellow together even all white together for each side of the AC circuit, was there a reason you did not?

[@MrElectron]

No reason... i was short on wires so i had to use other colours.

[@MrVeryCranky]

Try using wire rated for the current.

[@davidbrewer7937]

The design will fail...Above the Vf drop of each diode, there are differences in the ESR of each rectifier diode which sees the diode with the lowest resistance carrying more current than the others causing heat & eventual failure a this heat compounds the cascade failure. This is why large power rectifiers use hockey puck or stud mount devices...

[@Chuffin_ell]

You could always put a welding clamp on the lead with a filler rod. DC welding uses considerable current. This gives me an idea to use more robust rectifiers in parallel as a means to rectify AC for DC stick welding….

[@solrac7986]

Check the datasheet for the device he's using. It has a 700 volt RMS rating and 1000V PIV rating... But, yeah, the wiring and method is no good for the amperage of each bridge (35A) singularly, let alone in parallel.

great video my friend. I have a question that I believe you will know. If I have 3,000 volts at 30Khz coming down wires to a transformer. How can I change the 3,000 volts 30KHZ to 120 volts at 60Hz?

[@MrElectron]

Step down from 3000v 30 khz to 16v 30khz via ferrite core transformer. After that, use a bridge rectifier and a filter circuit to convert it to dc after that use any inverter with an output of 120v ac 60hz.

[@Biokemist-o3k]

@@MrElectron can I run the 3000volts 30Hz into a Bridge rectifier (using 2cl series diodes I suppose) and into a capacitor(what should I use as a capacitor)(What should I use as a filtering circuit?) Thank you so much.

[@Biokemist-o3k]

Also is there any way to change the let's say 2000 volts 30khz into a form that a microwave transformer can take in and output 120 volts ac. You are the smartest person I know my friend!!

[@nick8231]

Where are you getting 3,000 volts at 30khz

[@Biokemist-o3k]

@@nick8231 Comes from a hydroelectric installation . I stepped it up to transmit it over long stretches. This is out in the Wild Wild West of Pennsylvania where it is alot more inexpensive to transmit High Voltage DC over thin wires than 60hz very dangerous electricity and current. It is almost what big Electrical companies do. It is What Japan just started doing. Type in HVDC transmit and I believe it comes right up. I am debating whether to change it into 2,000 volts and modify the circuit to use a microwave oven transformer. Interesting there was a guy who had a radio show that was in every country. He was a big HAM radio guy as well. From the Towers he had up in the midwest he got a constant 2,000 volts at 40khz. The electrical company collected and paid him for that electricity. It makes sense now that I am in a similar situation. Why do you ask?

Nice bridge rectifier... but your wires are too thin. Get thicker wires and you will have a lot more amps.

[@istvanff]

[@helicopter7730]

Mr Electron, you really have no idea about electronics design. Bridge rectifiers cannot simply be connected in parallel and assume the current will be shared equally between each of them. Even a small difference in their forward voltage drop due to manufacturing tolerances will result in uneven current sharing, causing one bridge rectifier to pass most of the current and eventually being destroyed. To do this correctly there must be equalizing resistors in place. Thats exactly the reason why this type of design is NEVER used to rectify high currents.

[@chrisowen2925]

If you follow how he soldered each of the banks using the same wire colors, but when he connected the banks together it was a crapshoot for what color was connected to other colors... I am not sure why you would randomly connect red and yellow coded wires together in such a circuit you easily could connect an AC to a DC using that random color choice method as the video looks to show. I would even have used white and yellow exclusively for AC saving my black and red for DC polarity.... I Can not determine by the video why one would connect it as he did....It works but a) for how long b) random wire connections like that are dangerous for a follow-up person to use this device and think that the red positive is only DC, not AC as it looked like it was used in the video. I think he has only 220 where he is but AC and DC are different and should be coded and treated differently.

[@chrisowen2925]

You need a BALANCED set of rectifiers. Nearly impossible to have with a random drawer of these as each one can be slightly different brand new. So it is a matter of how long until it burns out. I built a charger for my battery in my truck that runs all the extra gear, its a very large battery and needs to charge at night to service all day long, I looked into using multiple rectifiers but found out it was easier to buy a single large one then bridge them into a bank this way. It will fail eventually under continuous use unless you add parts to balance it out, something I was not interested in doing. To the "Do you Understand ?" comment, I find many things he builds to NOT be something I want or need but find them interesting to watch for ideas. He is not building YOUR projects he is building something for himself and sharing them for others to see and try if possible. Some are battery/portable and others are connected by a line to the wall so maybe you can make a video combining both worlds. I would like to build a controlled shorted element, air displacement device that would run from 12Vdc, The element I chose I think is to large to do what I want, so I am watching to see if one of his videos might lend a clue to my project. Maybe he could even respond to an email I sent to him also if he has time. Oh by the way I am looking to build a heater for my truck but want something that can produce more than 300W of heat since that is the max I can find built ready to go at stores. I am thinking of a 1000W design. I will trip over the solution sometime. Do you Understand? Had to use your comment there.
