text: <s>[INST] Powerflex 755TR Drives Hi All, Is there a white paper available that can answer a specific question, the question being  Why does a Active Front End drive (PF 755TR) maintain unity or near to unity power factor. [/INST] Hi Rahul, That is a pretty specific question. I found this technote on calculating power factor correction for a 755T drive: QA46151 I don't think that is quite what you are looking for though. Page 34 (2-16) of this manual: https://literature.rockwellautomation.com/idc/groups/literature/documents/um/pflex-um002_-en-p.pdf Might be closer to what you are looking for. Hope this helps. Regards, RM \\n </s>
