摘要： PROBLEM TO BE SOLVED: To reduce a current capacity that flows into and out of a capacitor. SOLUTION: A voltage boosted by a boosting converter CONV1 is accumulated in a smoothing capacitor C. This voltage is supplied by inverters INV1, INV2 to motors MG1, MG2 as prescribed AC currents. By adjusting the phase or frequency of a carrier wave in the PWM control of a switch in the boosting converter CONV1 and a carrier wave in PWM controls of switches in the inverters INV1, INV2, pulse currents from the inverters INV1, INV2 that flow into and out of the smoothing capacitor C are offset with a pulse current from the boosting converter CONV1 so that the capacity of the current that flows into and out of the capacitor C is reduced.

摘要： PROBLEM TO BE SOLVED: To maintain appropriate operation by the drive of other arms, even in the failure of an inverter arm. SOLUTION: Inverter circuits 30 and 32 supply a current to motor coils 24 and 26, respectively. When the arm of the inverter circuits 30 and 32 fails (for example, a series of two transistors) and no current can be outputted, the current output from other arms is controlled, so that the output of the failed arm is compensated, thus inhibiting the generation of torque ripples of the motor 22, and preventing the adverse effects to the current between the neutral points which are located between the two motor coils 24 and 26 for supplying current.

摘要： PROBLEM TO BE SOLVED: To output torque from a motor and to reduce torque ripples even when one phase of the motor or an inverter circuit becomes abnormal. SOLUTION: Since the potential of the neutral point of the motor is fixed by a second DC power source, even when one phase of the motor or inverter circuit becomes abnormal, in a drive power output apparatus fitted with a first DC power source 30 to be connected to the positive electrode bus-bar 26 and the negative electrode bus-bar 28 of the inverter circuit 24, and a second DC power source 32 to be connected to the negative-electrode bus-bar and the neutral point of the motor. It is possible to obtain motor torque by causing current to flow in each of the other normal phases. When the motor is one to be driven on a three-phase AC, it is possible to prevent its torque ripples by making the phase angle differences between phase currents sixty degrees. Since the motor torque reduces to about sixty percent of its normal-time value, the gap between a torque command T* and the motor torque caused by the abnormality of the one phase can be reduced by correcting the command T*.

摘要： PROBLEM TO BE SOLVED: To provide a way for outputting a power by individually driving a plurality of motors using a low DC voltage, and enhancing efficiency of a unit. SOLUTION: A chargeable and dischargeable capacitor 32 is connected to a positive electrode busbar 22 and a negative electrode busbar 24 of inverter circuits INV1, INV2, and a DC power 30 is connected to the negative electrode busbar 24 and a neutral point of a motor MG1. Transistors T11 to T16 of the inverter circuit INV1 are switch-controlled based on a phase-voltage command value to which a DC component and an AC component are added. And also, an inter-terminal voltage of the capacitor 32 is controlled by the DC component using a voltage higher than that of the DC power 30, and the motor MG1 is drive-controlled by the AC component as well. Then, the motor MG2 is drive- controlled individually from the motor MG1 by switch-controlling transistors T21 to T26 of the inverter circuit INV2.

摘要： PROBLEM TO BE SOLVED: To execute the transmission and reception of power between two power supplies in a wide range of an operational condition, in a power device that can feed power to one motor from the two power supplies via different inverters. SOLUTION: AC power is fed to the motor 20 from the DC first power supply 12 via the first inverter 16. AC power is fed from the DC second power supply 14 via the second inverter 18 and a transmission coil 24 that is arranged so as to correspond to each phase. Low-potential side terminals of the first and the second power supplies are connected by a connecting line 26, and power transmission and reception by a DC between the power supplies is hereby made possible. Since the transmission coil is arranged independent from the motor, magnetic coupling between the transmission coil and a stator coil 22 of the motor is eliminated or reduced, and an effect to the operation of the motor can be reduced, thus enabling the transmission and reception of the power between the two power supplies to be conducted under a wide operational condition.

摘要： PROBLEM TO BE SOLVED: To reduce capacitance of a capacitor for smoothing by smoothing voltages of a plus and a minus DC voltage buses which are used in common by a plurality of inverters for driving a plurality of motors. SOLUTION: Phase difference of carriers in PWM control is set as 90 degrees when two motors are together in the driving state or in the damping state (S104), and phase difference of carriers in PWM control is set as 180 degrees when one is in the driving state and the other is in the damping state (S106). By setting the phase difference of the carriers as 90 degrees when both of the motors are in the driving state or in the damping state, pulses of an inverter flowing-out current which pulses correspond to the respective motors are made to appear alternately, and voltages of the plus and the minus DC voltage buses are smoothed. By setting the phase difference of the carriers as 180 degrees when one is in the driving state and the other is in the damping state, pulses of an inverter flowing-out current which pulses correspond to the respective motors are canceled, and voltages of the plus and the minus DC voltage buses are smoothed. As a result capacitance of the capacitor for smoothing can be reduced.

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.
