  "textContent": "A DC overhead wire 1, a first power converter 21, a second power converter 51, and a power storage device 52 are electrically connected via a direct-current common section 90. The power storage device 52 is also electrically connected to a first input and output end located on the opposite side of the direct-current common section 90 in the second power converter 51. According to an input form of electric power, the first power converter 21 operates as a DC/AC converter or an AC/DC converter. The second power converter 51 operates as a DC/AC converter, an AC/DC converter, or a DC/DC converter. The power storage device 52 is charged using direct-current power supplied from the direct-current common section 90 or the first input and output end side. The power storage device 52 discharges desired direct-current power to the direct-current common section 90 or the first input and output end side. A control device 100 freely adjusts, according to the input form of the electric power, the voltage of the direct-current common section 90 to a desired voltage including a high voltage or a low voltage.",
