<P>PROBLEM TO BE SOLVED: To provide a power conversion device which converts a DC power to an AC power of an output frequency that is set at present, outputs the AC power, and can set an amount of change at a shorter interval when the change is imparted to the output frequency. <P>SOLUTION: The power conversion device which converts the DC power to the AC power of the output frequency that is set at present and outputs the AC power, comprises a change imparting part which performs a change imparting operation as an operation of imparting the change to the output frequency. The change imparting part divides a change imparting period in which the change should be imparted into a plurality of sections that are shorter than a cycle of the AC power, and sets the amount of the change for each section. <P>COPYRIGHT: (C)2012,JPO&INPIT |
