Abstract
A control apparatus of an inverter that controls the drive of a traction motor of a vehicle is described. At a time when the vehicle starts moving by the drive of the traction motor, the control apparatus executes control processing to set a carrier frequency of the inverter to a low frequency within an audible range, and at a time other than when the vehicle starts moving, the control apparatus executes control processing to set the carrier frequency to a high frequency higher than the low frequency.
