A power conversion device according to an aspect of an embodiment includes a power conversion unit and a control unit. The power conversion unit includes N (N is an integer number not less than two) power converters that output voltages on the basis of base signals having the same period and phase differences equivalent to �N of the period of the base signal. The control unit controls the N power converters by using � of the period of the base signal as a control period and shifts each of control timings of the N power converters by the �N of the period of the base signal.
