Abstract:
1. A control apparatus for an AC electric motor vehicle including a converter that converts an AC voltage input from an AC overhead wire via a transformer into a DC voltage, an inverter that converts the DC voltage into an AC voltage, and a motor that is driven and controlled by the inverter, the control apparatus comprising: a torque-command calculating unit that calculates a torque command value of the motor and outputs the torque command value to the inverter; and a static inverter that supplies electric power to a load mounted on the AC electric motor vehicle, wherein when the AC voltage is not applied to the converter, the torque-command calculating unit calculates a regenerative torque command value corresponding to power consumption of the static inverter, based on a rotor frequency of the motor, an input current of the static inverter, and an input voltage of the static inverter, and the inverter supplies, according to the regenerative torque command value, regenerated power generated by the motor to the static inverter.
