A matrix converter includes first to third AC reactors connected in series with first- to third-phase outputs of three-phase AC electric power, and a first cooling fan that generates cool air for cooling the first to third AC reactors. The first to third AC reactors are arranged side-by-side in a direction intersecting a direction in which the cool air flows.
