Abstract
A power conversion device includes a converter, an inverter and a control circuit that controls them. The control circuit generates: first control signals that control the converter, on the basis of a first carrier wave; and second control signals that control the inverter, on the basis of a second carrier wave having a frequency and a phase that are different from those of the first carrier wave. The frequency of the first carrier wave and the frequency of the second carrier wave have a predetermined relationship therebetween based on a current of a capacitor connected in between the converter and the inverter.
