Abstract
An apparatus and a method for that reduce a common mode voltage are provided. The apparatus includes a detecting unit that is configured to detect a common mode voltage between a drive shaft and a frame of a drive motor. In addition, a gate resistance unit of a power module is connected to the drive motor. A controller is configured to adjust a magnitude of resistance of the gate resistance unit, based on a magnitude of the detected common-mode voltage and a magnitude of a predetermined reference voltage.
