Abstract:
An electric vehicle propulsion control device having a power storage device includes: a first switch configured to perform opening and closing of a circuit between an overhead wire and a power converting unit; a second switch configured to perform opening and closing of a circuit between the power converting unit and a motor; a switching unit configured to select a terminal on a side of the power converting unit to which the first switch is connected or a terminal on a side of the power converting unit to which the second switch is connected and connect the terminal to the power storage device; and a control unit configured to control the power converting unit, the first switch, the second switch, and the switching unit to switch a connection destination of the power converting unit and cause the power converting unit to operate as an inverter or a DC/DC converter.
