Abstract
A CT system includes a gantry having a rotatable base and having an opening for receiving an object to be scanned, and an AC-to-DC converter coupleable to a 3-phase AC facility power, and coupled through a DC bus to a gantry motor to rotationally drive the rotatable base using DC power from the AC-to-DC converter. Rotational energy in the rotatable base is converted to DC electrical energy in the gantry motor during gantry braking, and provided to the DC bus.
