The power conversion device includes a power converter circuit which includes a plurality of unit converters connected in series, and a controller. The unit converter includes one or more switching elements and a capacitor. The controller transmits, to the unit converter through a first transmission medium, information on a switching command for the unit converter. The unit converter transmits, to the controller through a second transmission medium, information on at least one condition of the unit converter. The first transmission medium is an optical fiber, and the second transmission medium is a wireless communication channel.
