A power conversion device includes a switching signal generation unit that generates switching signals so that time points of at least one of pairs synchronize with each other. A first pair includes a rising time point at a first junction point of a first single-phase leg, and a falling time point at a second junction point of a second single-phase leg. A second pair includes a falling time point at the first junction point and a rising time point at the second junction point. The switching signal generation unit determines time points to turn on or turn off for upper arm switching element and a lower arm switching element based on phase currents respectively at a rising time point and at a falling time point of the terminal voltages.
