A control device for a power converter includes a voltage command value limiting unit configured to limit each phase component or an absolute value of a vector of a voltage command value to be equal to or less than a value set in advance. With such a configuration, the control device for the power converter limits each phase component or the absolute value of the vector of the voltage command value to be equal to or less than the value set in advance. Therefore, it is possible to prevent overvoltage of the output from the power converter when impedance rapidly increases on the output side of the power converter.
