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 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.

摘要翻译：要解决的问题：在能够在宽范围的操作条件下在两个电源之间执行电力的发送和接收，在通过不同的逆变器从两个电源向一个电动机供电的电力设备中。
解决方案：交流电源经由第一反相器16从DC第一电源12馈送到电动机20.交流电源经由第二逆变器18和直流二次电源14被馈送，传输线圈24被布置以便对应于每个阶段。第一和第二电源的低电位侧端子通过连接线路26连接，并且因此能够在电源之间通过DC的电力传送和接收成为可能。由于传输线圈独立于电动机布置，传动线圈和电动机的定子线圈22之间的磁耦合被消除或减少，并且可以降低对电动机的操作的影响，从而能够发送和接收两个电源之间的电力在广泛的运行条件下进行。版权所有（C）2005，JPO＆NCIPI

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.

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 make it possible to freely set the voltage ratio of a power source at the input side of an inverter to the other power source connected between coils. SOLUTION: Output terminals of the inverter INV are connected to each terminal at both ends of coils L1, L2. A battery B is arranged between middle points of the coils L1, L2, and a capacitor C1 at the input side of the inverter INV. By adjusting the duty ratio of each transistor of the inverter INV, each input terminal of the coils L1, L2 is controlled independently, and thereby electric potentials at the middle points and phase currents of the coils L1, L2 are controlled. A current flows in such a way as to determine a voltage of the capacitor C1 so that the difference of the electric potentials at the middle points of the coil L1, L2 can become the same with the voltage of the battery B. As a result, the ratio of the voltage of the capacitor C1 to that of the battery B can be set freely. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a motor drive system wherein torque ripples can be made smaller in rectangular wave control. SOLUTION: The motor driven system comprises an inverter which receives input from a high-voltage direct-current power supply, and converts it into a predetermined alternating current and outputs it; a motor which is driven by the output of the inverter; a low-voltage direct-current power supply connected with the neutral point of the motor; and a controller which controls the operation of the inverter. The controller controls the operation of the inverter with a predetermined rectangular wave and inserts breaks constituted of output inverted sections of predetermined width into the rectangular wave. At the same time, the controller varies the position of insertion of the breaks, according to the ratio of the voltage of the high-voltage direct-current power supply to that of the low-voltage direct-current power supply. A break, constituted of a section of a 0 voltage of a rectangular wave is chopped, when the inverter is driven with the rectangular wave. By having the position α and the width β of this break optimized, torque ripples are suppressed. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To suppress and control counterelectromotive voltage produced in coils without an increase in the size of a unit.
SOLUTION: To reduce the number of flux linkages from the permanent magnets of a rotor 10 to a stator 12, fixing of the stator 12 by a fixing mechanism 16 is canceled with the coils of the stator 12 substantially opposed to the permanent magnets of the rotor 10. The current passed through the coils of the stator 12 is controlled so that the magnetic force generated by the coils of the stator 12 and the magnetic force generated by the permanent magnets of the rotor 10 repel each other. The unfixed stator 12 is thereby moved to the opposite side to the rotor 10 in the direction of axis of rotation. When the stator 12 is moved to the opposite side to the rotor 10 in the direction of axis of rotation, the stator 12 is fixed with the fixing mechanism 16.

摘要： PROBLEM TO BE SOLVED: To provide a structure which can reduce the number of permanent magnets while securing desired motor torque.
SOLUTION: An axial permanent magnet motor includes a rotor having a plurality of the permanent magnets disposed at predetermined intervals along the rotating direction of a rotary shaft so that poles are alternately disposed, and a magnetic element 24 disposed between the permanent magnets 20. Then, when a rotating magnetic field is generated in a stator disposed at a position opposed to the rotor, magnet torque is generated between teeth of the magnetized stator and the permanent magnet 20, and reluctance torque is generated between the teeth and the magnetic element 24. As a result, even if the number of the permanent magnet 20 is reduced and the magnet torque is reduced, it is compensated by the generation of the reluctance torque, and desired motor torque is secured.
