    DC vs. ACBrakingCommon DC Bus AC DrivesMost existing rolling mills have DC drives; because until recently, AC drives did not have the performance necessary. Since all drives in the rolling train must have similar performance, early attempts at installing some AC stands in a DC rolling train required the detuning of existing DC drives. Today the opposite is true, the above mentioned rolling mill has a total of 17 stands, with stands 1 to 13 being powered by modern DC digital drives. In this case the four new AC drives were "de-tuned" to match the performanc
