Abstract:
(EN)

PROBLEM TO BE SOLVED: To provide an electric vehicle propulsion control device which can be reduced in cost, size and weight.

SOLUTION: 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 either selecting a terminal on the side on which the switch 4 of the power conversion unit 8 is connected or selecting a terminal 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 a connection destination of the power conversion unit 8 and operates the power conversion unit 8 as an inverter or a DC/DC converter according to the operating mode of the electric vehicle.
