  "textContent": "Problem to be solved: To provide an electric power conversion device that normally operates, even when the voltage of a DC power supply or the like changes, by suppressing electric oscillations in an LC filter circuit so as to suppress transient oscillations in the voltage of the capacitor. Solution: An electric power conversion device includes a power conversion circuit for receiving electric power from an overhead wire through an LC filter circuit composed of a reactor and a capacitor and converting the electric power to output and a control unit for controlling the power conversion circuit, wherein the control unit is provided with a delay unit for delaying the voltage across the capacitor so as to produce a first control signal, produces a second output voltage instruction from the first control signal and a first output voltage instruction specifying the magnitude of the output voltage of the converted power, and controls the power conversion circuit based on the second output voltage instruction.",
