Abstract
A power conversion apparatus includes: a power converter that includes a plurality of switching elements; and a controller that controls the plurality of switching elements. The controller includes: a command generator that generates a voltage command vector; a synthesizer that synthesizes a correction vector with the voltage command vector to generate a synthetic vector; an adjuster that adjusts an output time of a plurality of voltage vectors from the power converter, the output time being corresponding to the synthetic vector; and a correction vector generator that generates the correction vector on the basis of an adjustment result of the adjuster.
