A power conversion device includes: a three-phase inverter including a plurality of switching elements; and a controller configured to PWM-control the three-phase inverter based on three phase voltage commands. The controller generates a zero-phase voltage command using a two-phase modulation scheme and a third harmonic component of the three phase voltage commands. The controller adds the generated zero-phase voltage command to each of the three phase voltage commands to thereby correct each of the three phase voltage commands. The controller compares each of the corrected three phase voltage commands with a carrier wave, to thereby generate a control signal for controlling switching of the plurality of switching elements.
