Electric-vehicle control device

An electric-vehicle control device that includes a power converter that converts a direct-current voltage of a filter capacitor, which accumulates electric power supplied from an overhead wire, into a desired alternating-current voltage and drives a motor, which is a load;

• a control unit that controls the power converter;
• and a regeneration control operation unit that performs a control operation for returning regenerative power generated by the motor to the overhead wire, wherein
• the regeneration control operation unit includes:
• a first control system that calculates, on a basis of a voltage of the overhead wire or the filter capacitor, a first torque suppression amount for suppressing regenerative torque of the motor;
• and
• a second control system that calculates, on a basis of regenerative power that is calculated using a voltage of any of the overhead wire and the filter capacitor and an electric current flowing to the overhead wire, and a torque command, a second torque suppression amount for suppressing regenerative torque of the motor, and
• regenerative torque of the motor is controlled on a basis of the first torque suppression amount and the second torque suppression amount.
