- This huge 2000A POWER module, is made of 4 parallel 500A modules,
we go inside one of the modules to find 28 IGBT chips and 12 large diode chips.
Temperature sensor 1k ohm and current transformer also designed inside the module,
very clever compact design. This module including heatsink is 6.5kg

I use auto generated subs, i am sorry there are a few spelling errors,
maybe one day they can do it better..

(Thanks to all my Sponsors / Traders / Swappers / Sellers / Buyers, without your support and constant flow of cool items in/out, none of this would be possible)
Goop cleans off if you use MEK to dissolve it. Also unfortunately tends to strip the soldermask off the ceramic board. Ceramic is either soldered to the aluminium substrate with a low temperature aluminium compatible solder, or has thermal epoxy holding it in place.
14:00 could be that current transformer is using one coil to drive the core into saturation, and a second for sensing, so any DC current offsets the saturation point.
Маленька котушка дає сигнал зворотного зв'язку на спеціальний підсилювач постійного струму, що живить велику котушку. Підсилювач створює у великій котушці такий струм, щоб магнітна індукція в сердечнику дорівнювала нулю. При цьому струм у великій котушці буде точно пропорційний до первинного струму. Не тільки на змінному струмі, а й на постійному струмі.
The small coil gives a feedback signal to a special DC amplifier that powers the large coil. The amplifier creates such a current in the large coil that the magnetic induction in the core is zero. In this case, the current in the large coil will be exactly proportional to the primary current. Not only on alternating current, but also on direct current.
This is a closed loop fluxgate transducer, likely based around a TI DRV401 or similar chip. A saturable magnetic strip sits inside the excitation coil, and the drive circuit works to cancel out any even harmonic generation by servoing the bias coil current. This happens when the bias current cancels out the main current, scaled by the number of turns on the bias winding. At higher frequencies, it acts like a regular transformer, with the main current inducing a scaled current in the bias coil. This gives a flat response from DC up to hundreds of kHz usually.

What a great microcircuit!
It's a pity that I didn't have one like that in 1984 and then I had to make a current sensor with this operating principle from discrete elements.
Never seen anything like that before!
Coils at 90 degrees offset. Interesting.
Thank you for the video , i always wondered how the inside of these modules looks like .great video
The goop is silicone dielectric gel, you can remove it with silicone oil or brake fluid.
Used semi-packs are more or less guaranteed NOT to work...
Might be just working old stuff from decommissioned machinery...
Especially if offered as "untested" as it's pretty easy to test them. 😂
Hefty they are, yes 😮💪
Lots of power to handle 2000A
I've been working with "only" 300A systems/inverter for heatpump compresors...
They do have 2 IGBT running in parallel for each of the 3 outputs.
Love the part with the sticky sticky stuff... 😂😉😂 ...been there, too
thickest bond wires iv ever seen, could you caliper one of them for me
