ABB ACS350 drive - IGBT demage
« on: November 10, 2017, 11:29:26 am »
Hi,
Does anyone know the parameters of IGBT K200A02 (TYCO Electronics) used in ACS350.
I can't find any datasheet for K200A02.

Regards,
up8051

This is  crazy price  :palm:
New IGBT with probably same parameters SKiiP12NAB126V1 cost 30Euro.

I'm looking for confirmation that K200A02 is IGBT 1200V 15A

At this price, it is probably an Ebay fake device.

SEmikron (true) equivalent seems to cost more or less 80 euros.

Price from official Semikron shop is 29,79Euro +15Euro (shipping) +VAT
http://shop.semikron.com/en/Products-and-Shop/Product-Groups/IGBT-MOSFET-Modules/MiniSKiip/SKiiP-12NAB126V1.html?listtype=search&searchparam=skiip12nab126v1&redirected=1

I still looking for confirmation that K200A02 is IGBT 1200V 15A and can be replaced by 12NAB126V1.

I think you need a VAT nummer to buy from official Semikron shop.

It doesn't matter. up8051 simply proved a 30 euro Semikron can be genuine.

IGBT SKiiP12NAB126V1 ordered in Semikron.
I hope it is compatibile with K200A02.

I can't say much for the sourcing of the suspect IGBT,  but if the IGBT shorted out.... Look at how the driver circuit is laid out. Follow the leads if any and see what drives the IGBT inputs. Since you are dumping a few coins into a new IGBT it may serve you well to check all the driver parts (replace them if you find just one issue). Usually symmetrical .  I worked on inverter equip for years and found that in a lot of cases, when the IGBT failed (a nice short) it sent a spike into the driver circuit (and things into the wall) and damaged something, even very minor.  So it's worth the time to check. Since I was not paying for the parts, still only had one chance as they are not cheap, more current, more money. The advice from the factory was to slowly ramp up input voltage and monitor current flow. If it was increasing to fast after the caps charged than something was wrong (and that may have lead to the failure). Pretty hard to due when you don't have all the fancy equipment. So....... check everything.  There is no real way to test a unit before hand unless you have some factory figured procedure. As for testing the IGBT there was a simple exercise (unit) circuit, but it was only a go/no-go, no real stress testing. Don't know the specifics of your unit, but the concept is the same. Some thing took out the switch, it may have failed all by it's lonesome, but than something else may have pulled to much current through it, that will be pretty obvious then.
