A power conversion apparatus includes: a power converter that includes a plurality of switching elements; a switch controller that controls the plurality of switching elements so that the order of outputting a plurality of kinds of voltage vectors from the power converter is opposite in a first half and a latter half of a carrier period; a DC-side current detector that detects a DC-side current of the power converter; and a phase current detector that detects one phase current among three phase currents on the basis of the detected DC-side current at a detection timing, the detection timing being selected from a first-half timing and a latter-half timing of the carrier period at which the same kind of voltage vector is output. The phase current detector includes a timing switcher that alternately switches the detection timing between the first-half timing and the latter-half timing.
