A control apparatus for an AC electric motor vehicle including a converter 3 that converts an AC voltage input from an AC overhead wire via a transformer 2 into a DC voltage, an inverter 4 that converts the DC voltage into an AC voltage, and a motor 6 that is driven and controlled by the inverter 4 includes: torque-command calculating units 11 and 12 that calculate a torque command value of the motor 6 and output the torque command value to the inverter 4; and a static inverter 7 that supplies electric power to a load mounted on the AC electric motor vehicle. When the AC voltage is not applied to the converter 3, the regenerative-brake-torque-command calculating unit 11 calculates a regenerative torque command value TRQ1 corresponding to power consumption of the static inverter 7, and the inverter 4 supplies, according to the regenerative torque command value TRQ1, regenerated power generated by the motor 6 to the static inverter 7. |
