Abstract
The present invention relates to an inverter device for a microgrid, and a method for controlling the same, the inverter device including: a waveform detector detecting a voltage waveform and a current waveform applied to a load; a control unit determining whether a sine wave appears based on the detected voltage waveform and the detected current waveform and performing voltage control or low order harmonic compensation depending on a determination result; and a switch generating a voltage waveform in a form of the sine wave by being turned on/off depending on a control signal received from the control unit and supplying the generated voltage waveform in the form of the sine wave to the load.
