Abstract: A power conversion device includes an inverter which converts a DC power supplied thereto from a power supply device to an AC power using an operation of a switching element and outputs the AC power toward a load a current meter which measures an output current from the inverter, and a control unit which controls the operation of the switching element to change an output voltage waveform from the inverter. The control unit changes the output voltage waveform on the basis of the measured output current.
