Abstract
A power conversion device includes: an inverter that includes a switching element and converts DC power into AC power; a current detector that detects an output current of the inverter; and a controller that controls the inverter to allow the output current detected by the current detector to follow a current command value having a sinusoidal waveform. The controller compares a current deviation of the output current from the current command value with a hysteresis band to control switching of the switching element. The controller sets the hysteresis band so that a hysteresis band in a zero-crossing area of the current command value is smaller than a hysteresis band in a peak area of the current command value.
