The present invention provides a power conversion apparatus that can reduce a number of switching times. A carrier generating unit applies a carrier (C1) that monotonically decreases to a switching control unit during either one of a first period (T10) that is a period immediately following a period in which a voltage command value (V**) is a value not more than a minimum value of the carrier, the voltage command value taking a first predetermined value larger than the minimum value of the carrier in the first period, and a second period (T10) that is a period immediately preceding a period in which the voltage command value is not less than a maximum value, the voltage command value taking a second predetermined value smaller than the maximum value in the second period, and applies a carrier (C2) that monotonically increases to the switching control unit during either one of a third period (T13) that is a period immediately following a period in which the voltage command value is a value not less than the maximum value, the voltage command value taking a third predetermined value smaller than the maximum value in the third period, and a fourth period (T13) that is a period immediately following a period in which the voltage command value is not more than the minimum value, the voltage command value taking a fourth predetermined value larger than the minimum value in the fourth period. |
