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.

Abstract: The present invention relates to a power module and a manufacturing method therefor, and an inverter apparatus having a power module. The power module of the present invention comprises: a power device for converting and outputting a frequency of an input power source; and a housing accommodating the power device therein and forming flow paths for a cooling fluid on both sides of the power device such that the cooling fluid can contact both sides of the power device. Accordingly, both plate surfaces of the power device can be in direct contact with the cooling fluid so as to be quickly cooled.
