PROBLEM TO BE SOLVED: To provide a power-converting device capable of outputting a required output voltage for the fluctuation of a DC voltage inside the power-converting device. SOLUTION: This device is provided with an output voltage command correcting means 9, that detects the fluctuation of a DC voltage using the outputs of an output voltage detecting means 7 and an output voltage command calculating means 8, and corrects an output voltage command value that the output voltage command calculating means 8 issues, when the DC voltage of a smoothing capacitor 3 as a DC-voltage source fluctuates. Thus, the fluctuation of the AC output voltage of the power-converting device can be suppressed, and the required AC output voltage can stably be supplied for the fluctuation of the DC voltage inside the power-converting device. |
