Abstract
An inverter device includes: a step-up circuit; an inverter circuit; a control unit for controlling the step-up circuit and the inverter circuit; and a reactor provided on an electric path for outputting the converted AC power to an AC system. An output current target value is calculated based on an input power value of DC power and a voltage value of the AC system, and a current target value and a voltage target value for the inverter circuit are calculated based on the output current target value, to control the inverter circuit. A current target value for the step-up circuit is calculated based on a current target value and a voltage target value that are common with the inverter circuit, and on a DC input voltage value, to control the step-up circuit. Thereby, output of the AC power is controlled.
