A(n) ___ is a device that changes AC voltage into DC voltage in a motor drive.

Explanation:
Converting AC to DC in a motor drive is done by a rectifier, which is a type of converter. In a drive, the incoming AC is turned into DC to form a DC link that the inverter can regulate to feed the motor. The device that performs this energy-form change is a converter. Inductors and capacitors store or filter energy but don’t convert AC to DC, and an inverter performs DC to AC conversion, not AC to DC.
