Abstract
A motor drive for conditioning power to be delivered to a load includes a current feedback circuit that monitors current being fed to a transformer connected between the motor drive and the load. Based on the total current input to the transformer, a controller adjusts the V/Hz profile along which the motor drive operates. In this regard, the motor drive operates according to a V/Hz profile during start-up that prevents transformer saturation.
