The present invention relates to a power converting device. According to an aspect of the present invention, the power converting device comprises: a current sensor configured to sense a current outputted from an inverter; a first current extracting unit configured to extract an AC current having a frequency equal to or greater than a preset frequency from a first current sensed by the current sensor; and a second current extracting unit connected to the current sensor and the first current extracting unit to extract a DC component included in the first current by referring to a second current outputted from the first current extracting unit. Therefore, the power converting device can increase economical efficiency. |
