<p>Provided is a power conversion device for, even when the voltage of a DC power supply or the like fluctuates, maintaining a normal operation by suppressing the electrical oscillation of an LC filter circuit and also suppressing a capacitor voltage transient oscillation. The power conversion device has: a power conversion circuit for outputting a converted power obtained by converting the power supplied from an overhead line through an LC filter circuit comprising a reactor and a capacitor; and a control unit for controlling the power conversion circuit. The control unit includes a delay processing unit for performing delay processing on the voltage on the capacitor to generate a first control signal, generates a second output voltage command from the first control signal and a first output voltage command that is the command for the magnitude of the output voltage of the converted power, and controls the power conversion circuit according to the second output voltage command.</p> |
