PROBLEM TO BE SOLVED: To enable traveling of a railway vehicle coping a high speed region regeneration brake that mounts the storage battery even when the power supply from the overhead is broken off.SOLUTION: A driving apparatus of a railway vehicle includes: an inverter device (2) that converts the high potential DC power input from an overhead by a current collector (8) to the AC power; an AC motor (3); a power storage device (1) that is connected with the high potential side of the inverter device (2) and can charge and discharge. The low potential side of the inverter device (2) is connected with the low potential side of the power storage device (1), a first breaker (51) is disposed between a high potential side of the inverter device (2) and the current collector (8), and a second breaker (52) is disposed between the high potential side of the inverter device (2) and the high potential side of the power storage device (8). When power is supplied from the overhead by a power supply control device (15), the first breaker (51) is turned ON, and the second breaker (52) is turned OFF, and when there is no power supply from the overhead, the first breaker (51) is turned OFF, and the second breaker (52) is turned ON and the power is supplied from the power storage device (1). |
