Sami Star inverters with new Rectifier
Sami Star inverters with new Rectifier
(OP)
Hi guys,
I am involved in one project where customer ask from us to install new abb igbt rectifier (ISU) on old abb Sami Star inverters. It is multidrive configuration with four Sami Star inverters.
I never worked with such old drives like Sami Star and it is very hard to find some documentation for this drive on net.
Is this configuration is possible to work together.
Can somebody give me some cataloque or hardware manuals for Sami Star dirves.
Any comments, thoughts and possible problems that somebody can see will be very helpfull.

Have you tried contacting ABB? Allen Bradley also used to brand-label that drive from Stromberg as the 1352 Series, they may have some scanned-in documentation available if you look.

Thanks for responses.
jreaf: Thanks for this information about Stromberg name of drive. I contact local ABB Serbia and now I waiting for response.
electricuwe: igbt rectifier can give bigger DC voltage, but also in this abb ISU type of rectifier you can define reference value for DC voltage, so this should not be a problem.
Any more eventual problems that somebody can see.
Or some manuals except the manuals that you can regulary download from ABB officiel site.

Also, I may be wrong on this but, if I recall correctly, the SamiStars were all Medium Voltage. The Allen Bradley "ABS" Stromberg 1352's were low voltage drives made by Stromberg and supported today by ABB even tho the front door says Allen Bradley. I believe SamiStar and the ABS drives were two separate product lines.

RE: Sami Star inverters with new Rectifier
I'm thinking that if the rectifier is an IGBT based 'controlled' unit, it should be able to control the DC link voltage as well. Not 100% but worth looking at.
RE: Sami Star inverters with new Rectifier
An it is in doubt, if an old inverter design can cope with that.
Therefore, check in detail before ordering.
RE: Sami Star inverters with new Rectifier
I dint understood this word "headroom" (i tried with dictionary but I didnt find anything).
What I meant to say is that on ABB igbt type rectifier (they call it ISU) you can define how much DC voltage you want. So this thing about DC voltage should not be a problem. Am I right.

as I'm not a native speaker I checked this word at www.leo.org --> no problem
- on the rectfier operation of an IGBT stack:
Do not rely on simple qualitative statements, check the specified range
or
- find some textbook on basics of power electronics to understand how an IGBT rectfifier works
