Abstract
A power conversion device includes a main circuit unit, a first current detector, a second current detector, a voltage detector, and a controller. The main circuit unit is connected to a DC voltage source and an AC power system. The main circuit unit includes an inverter including a plurality of switching elements. The main circuit unit converts a DC power to an AC power. The controller decides that whether the output current of the inverter falls within a range between an upper limit value and a lower limit value, stop an operation of the switching elements when the output current of the inverter falls beyond the range, and resume the operation of the switching elements when the output current of the inverter returns into the range.
