The purpose of the present invention is to inhibit an increase in the size and cost of a power conversion device including three or more single-phase inverters. Provided is a power conversion device (1) comprising three or more single-phase inverters (2) that each convert DC power into AC power and a control unit (4) that controls the single-phase inverters, wherein: when the absolute value of an output voltage of each of the single-phase inverters is defined as a voltage absolute value and the minimum value of the voltage absolute value is defined, the voltage absolute value of at least one single-phase inverter is set to a value obtained by multiplying the minimum voltage value by a power of 2 or a power of 3, and the voltage absolute value of at least another one single-phase inverter is set to a value obtained by multiplying the minimum voltage value including a decimal fraction by a real number.
