    摘要: In general, a control device for a railway vehicle controls an inverter device 4 based on a direct-current link voltage Vfc between the opposite terminals of a filter capacitor 3. In a circuit configuration according to the present invention, a direct-current voltage applied to the inverter device 4 during regeneration is the sum of a voltage Vb of power storage equipment 6 and an overhead wire voltage Vs as described later, so that only detecting the direct-current link voltage Vfc is not enough to separate the voltage Vb of the power storage equipment 6 and the overhead wire voltage Vs from each other, and it cannot be determined whether the current state is the state of light load regeneration or not. In the circuit configuration in which the power storage equipment can be connected in series with the inverter device 4, a voltage sensor that detects the overhead wire voltage Vs is provided between a current collector device 1 and a grounding point, and the power storage equipment is controlled based on the detection result from the voltage sensor.
