I am starting new post on a previous question.
In essence I need to feed a couple of motors rated 480V but I only have 240V available. I am have going back and forth with a buck-boost or using a normal 240V/3 to 480V/3 rated transformer listed for back-fed applications. My concern is the motors are controlled via a VFD and I understand the VFD my not like reverse fed xfmr.
My one line (attached) shows a step-up xfmr. reverse fed. I just don't know if this is the correct approach.
Thank you
Dan Craven
