I love repairing videos and this serie is abolutely catch me. I'm looking forward to the next part. I'm learning alot of things from you. I'm deeply from heart thank you.
Amazing ♥️
Kasyan 🤝
Every country needs Engineer like you ♥️
This is a great repair challenge taken up by Kasyan- Tv, which comprehensive electronics understanding must be coming from the fountain of a devine genius. I wish to be able to learn and to understand electronics as much as you. I,am looking forward for the third part of this greatly informative event. Stay blessed.
I just couldn't ressist clicking on this link ....can't wait for part 3💥💥
Really cool video. Looking forward to the third part.
how about Part 3 ?..... waiting.........😀
Wow this is so cool, just can't wait for the next episode.
you are doing great kasyan!
Slower switching on the IGBTs in this application is a BIG deal! You did the right thing wanting to go back to the original IGBTs. Don't be surprised if things don't go well with the slower pucks/bricks. The gate drive layout is always the Achilles heel in high current IGBT installations. In my opinion the driver boards are too far from the bricks. Too much lead inductance.
Thankyou for sharing again. What an phenomenal amount of time thought and work has gone into this and a video of it. And reading up, investigating and research. Im in awe.
Your describe is Amazing. I learnt some thing different from you. You are great. Best of luck.
Eagerly waiting for part 3.....
I love your thoroughness in leaving no stone unturned.
Have you put any thought into the bundles of twisted pairs running throughout the machine? They all seem to have the same amount of twist, meanibg they are more likely to cross-couple than twisted pairs that have various twist count per length. Also, should some of the signal lines be shielded?
Similarly, have you questioned the "grounding scheme"? I'm sure you are knowledgeable, but unintentional multiple return paths often get overlooked. Something like this needs to avoid ground loops and ground potentials between components, most ideally, a "star" arrangement, one single point at which all common return connections meet. Usually the best you practically do is a single, centralized low-impedence bus bar directly off the power supply return (isolated from the chassis earth).
Thank you for sharing this repair process. Did you measured the dead time between lower and upper part of the H bridge drivers. Often, overlapping issue (DC voltage circuit to short ) causes power modules and drivers to fail.
Those hose clamps on the water cooling loop are hot garbage. On a piece of equipment like this, I would spare no expense and put in some of those nice German made hose clamps.
You mean "spannbackenschelle made by Norma" or the band clamps from "geka" which are an insane quality piece of themself? YES
They didn't even have grommets for the wiring, this thing is sketchy, or as Diodegonewild would say "DODGEY!".
Sooopurrrr DODGEY lol
Designed with flaws copied with multitudes ,repaired many times ,throw parts at it ..
For the control system board, first, you should replace all of IC sockets with better quality ones. Replace with gold plated round pin ones.
Keep upload future progress then I can support with further simple suggestions.
You're a genius man, and do you have a nice measure device's.
Waiting for Part 3 👌
Good job
Thanks for video marketing 👌👍
Excellent 😊,I really appreciate you.please make any videos on pll 4046 chip for induction.thanks
hi, I'm really interested to know what happened after this video with regards to the machine.
The capacitor block you held up at 2:01 should be a single unit and not made up of individual capacitors. Such units are made specifically for this application.
nice videos in the future can you make a video for bldc motor controlers
very complicated for me..🤣😂
but video is so good
Can you make automatic power factor control device
could you please make a plasma cutter from induction welder
❤️
Hi tell single phase to three phase
With no moving parts
Only use transformers and capacitors .
Can i help you out ?
I disagree with the approach "it is someone elses property so I won't add the buffer". In the contrary, when it is someone elses property, I would rather make sure no component is overdriven, so when the predriver datasheet asks for an extra buffer, I would be very hesitant to not fit that buffer, once the larger power modules are to be installed. Mainly when it is already designed on the board as an assembly option. Of course, all such changes needs to be properly logged into the maintenance log book, so it won't come as a surprise with later service.
Next part 3 ???
With 8 modules, there must be pairs in parallel. Recipe for disaster if there's any time differences that make one module switch before the other.
Not that much when they are "soft switching" (turning ON when there is no voltage across them), it is a resonant system after all.
