Title: (EN) Electric vehicle propulsion control device, and railway vehicle system
Abstract: front page image
(EN) An electric vehicle propulsion control device having a power storage device (15) is provided with: a switch (4) that opens and closes a circuit between an overhead wire (2) and a power conversion unit (8); a switch (16) that opens and closes a circuit between the power conversion unit (8) and a motor (17); a switching unit (11) that connects to the power storage device (15) by selecting terminals on the side on which the switch (4) of the power conversion unit (8) is connected, or terminals on the side on which the switch (16) of the power conversion unit (8) is connected; and a control unit (1) that controls the power conversion unit (8), the switch (4), the switch (16), and the switching unit (11), and switches the connection destination of the power conversion unit (8) and operates the power conversion unit (8) as an inverter or a DC/DC converter, depending on the operating mode of the electric vehicle.
