Abstract: In a drive system of an AC motor in which a motor current is feedback-controlled, a motor current command is produced in a normal operation according to a torque command value on an optimum efficiency characteristic line so as to select an optimum current phase maximizing an output torque with a constant motor current amplitude. Conversely, when the AC motor produces an excessively generated power exceeding a regeneratable power quantity of the AC motor, a consuming operation is performed for intentionally increasing the power loss in the AC motor. In the consuming operation, the motor current command is produced according to the torque command value on a loss increase characteristic line to change the current phase from the above optimum value. Thereby, the power loss in the AC motor can be increased to consume the surplus power without causing instability in the motor control.

Abstract: A boost converter boosts a DC voltage of a DC power supply. An inverter converts the output voltage of the boost converter into an AC voltage. An AC motor is driven by the output voltage of the inverter. A control device which controls the boost converter reduces an output voltage instruction value of the boost converter in the case where the rotation speed of the AC motor is decreased and an absolute value of a variation rate of the rotation speed is not less than a predetermined value. The inverter is controlled in the control mode selected from a plurality of control modes including three modes of a sine wave PWM control mode, an overmodulation PWM control mode and a rectangular wave control mode. The control device of the boost converter reduces the output voltage instruction value of the boost converter only in the case where the control mode of the inverter is the rectangular wave control mode or the overmodulation control mode.

Abstract: A motor control apparatus includes a direct-current power source and an inverter circuit, which includes a switching element. The motor control apparatus receives a current command value in every control cycle and calculates a current deviation accumulated value by accumulating the current deviation between the received current command value and the actual current value that flows through a coil of a motor. The motor control apparatus then computes a voltage command value in accordance with the current deviation accumulated value and controls the switching timing of the switching element based on the voltage command value. The motor control apparatus judges whether the computed voltage command value exceeds a range of the voltage that can be output from the inverter circuit and causes saturation. If it is judged that the voltage command value is saturated, the motor control apparatus restricts the accumulation of the current deviation.
