摘要： PROBLEM TO BE SOLVED: To attain an effective operation in an inverter system provided with two inverters. SOLUTION: A three-phase motor currents are fed to a correction voltage addition/subtraction judging section 102. The addition/subtraction judging section 102 judges whether two of the three-phase motor currents are positive or not. If two are positive, a positive correction voltage ΔV is fed to an adder 104 and if two are negative, a negative correction voltage ΔV is fed to the adder 104. Output from the adder 104 is the voltage command value of a motor and the neutral voltage of the three-phase motor is corrected by adding the correction voltage. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To enhance the upper limit of the output torque from a motor without affecting the voltage of a capacitor as a drive power source. SOLUTION: A DC power source 40 is connected between the neutral points of the three-phase coils 24 and 26 of two Y connections without discrepancy of winding angle which are supplied severally with three-phase AC power from two inverter circuits 30 and 32 sharing a positive electrode bus 34 and a negative electrode bus 36, and also a capacitor 38 is connected between the positive electrode bus 34 and the negative electrode bus 36. The supply of the three-phase AC power is performed by the PWM control by the comparison between modulated waves, where tertiary harmonics having the same amplitude and frequency mutually in the same phase are superposed each on the three-phase modulated waves having the same amplitude and frequency mutually in the same phase, and triangular waves. Consequently, it is possible to enhance the upper limit of the output torque from a motor by reducing the amplitude maximum value of the modulated waves without oscillating the potential difference between the neutral points, that is, the voltage of the capacitor.

摘要： PROBLEM TO BE SOLVED: To provide a power output device which can drive an electric motor efficiently. SOLUTION: The power output device comprises a capacitor 30 which is connected with a positive electrode bus bar 26 and a negative electrode bus bar 28 of an inverter circuits 24, and a DC power sources 32 which is connected with a neutral point of a motor 22 and the negative electrode bus bar 28 of the inverter circuits 24. An electronic control unit 40 controls the inverter circuits 24 so that the voltage Vc between terminals of the capacitor 30 is equal to the set voltage Vc* by using the value which adds the voltage Vb of the DC power sources 32 detected by a voltage sensor 64 and the amplitude A of an order voltage V* applied to a three-phase coil of the motors 22 as the set voltage Vc*. This is based on that the three-phase voltage as the instructed voltage V* applied to the three-phase coil is controlled taking the potential Vb of the DC power source 32 as the center.

摘要： PROBLEM TO BE SOLVED: To lessen the frequencies of the appearance of zero-voltage vector and to reduce current ripples that may occur at the neutral point of an electric motor. SOLUTION: A motor is driven by a PWM control based on three-step voltage levels of 1/2VB, zero, -1/2VB by using two hierarchical triangular-wave carriers CAR1, CAR2 for each phase command. Compared with the PWM control with the two-step voltage levels of 1/2VB and -1/2VB, the frequencies of the appearance of the zero-voltage vector in which the voltage of each phase becomes the same can remarkably be lessened. Therefore, in a device in which the neutral point of the motor is fixed to a given potential, the ripples of a neutral point current can be reduced that is caused to occur as the zero-voltage vector is outputted. As a result, the loss in the motor can be lowered.

摘要： PURPOSE:To obtain a drive control apparatus, for an electric car, which prevents the aggravation of a drive feeling which is generated by a cogging torque or the like when the electric car is running at a very low speed. CONSTITUTION:Immediately after a vehicle has started or when the vehicle is running at a very low speed (106), the speed of a motor, for running, which is constituted as a permenant-magnet synchronous motor is feedback-controlled (102, 110). When the load of the drive motor is stable to a certain extent, the aggravation of a drive feeling due to a torque change can be prevented when the speed is feedback-controlled because a cogging torque or the like appears as a speed change. When the vehicle is not running at the very low speed (106) or when a braking operation is required (104), a torque open-loop control operation is performed (116, 120) so as to satisfy an accelerating and braking feeling or the like. When a control operation is changed over (114, 122), a torque instruction value is changed gently.

摘要： PURPOSE:To provide motor controller for electric automobile in which a clutch and a motor can be protected appropriately even when clutch operation is carried out similarly to an engine vehicle. CONSTITUTION:Upon disconnection of a clutch 21, torque command value for a motor 17 is lowered by an amount corresponding to the difference of friction between a normal engine and the motor 17 to decrease the number of revolution of the motor 17 before the clutch 21 is connected. When the motor 17 has been driven at a speed higher than a number of revolution prescribed for vehicle speed, torque command value is controlled to drop below a predetermined level thus decreasing the number of revolution of the motor 17 below a prescribed level before the clutch is connected. The clutch 21 and the motor 17 are protected by avoiding connection of clutch under a state where the motor 17 has high torque and high number of revolution.
