Abstract
The present specification relates to a motor control device, a motor control system, and a motor control method. The motor control device measures a ripple voltage of a DC link capacitor to determine an appropriate switching frequency according to the ripple voltage, and causes a plurality of arithmetic processing units to selectively control a switching operation of the switching unit according to the determined switching frequency.
