<p>Provided in the present invention is a power conversion apparatus wherein the number of times of switching can be reduced. A carrier generation unit supplies, to a switching control unit, a carrier (C1) that decreases monotonously during a first period (T10) that is one period subsequent to a period wherein a voltage command value (V**) takes a value not more than the minimum value of the carrier, and wherein the voltage command value takes a first prescribed value that is greater than the minimum value of the carrier, and/or a second period (T10) that is one period prior to a period wherein the voltage command value takes a value not less than the maximum value of the carrier, and wherein the voltage command value takes a second prescribed value that is less than the maximum value. The carrier generation unit also supplies, to the switching control unit, a carrier (C2) that increases monotonously during a third period (T13) that is one period subsequent to the period wherein the voltage command value takes a value not less than the maximum value, and wherein the voltage command value takes a third prescribed value that is less than the maximum value, and/or a fourth period (T13) that is one period prior to the period wherein the voltage command value takes a value not more than the minimum value, and wherein the voltage command value takes a fourth prescribed value that is greater than the minimum value.</p> |
