摘要： PROBLEM TO BE SOLVED: To detect a load current from the on-voltage of an inverter main circuit element. SOLUTION: A voltage (the on-voltage), when a switching element Q or a diode D is in conduction state in the main circuit elements 18U-2, 18V-2, and 18W-2 of the lower side arm of the inverter 12, is detected by voltmeters 16U, 16V, and 16W. Since only the voltage during turning-on is extracted and detected, the voltage of about ±1.5V needs only to be detected and detection with high accuracy can be conducted.

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 reduce loss in an inverter system. SOLUTION: A DC power source is arranged between the neutral point of the star-connected coil of a motor M2 and the negative side DC line of a second inverter INV2. The neutral point of the star-connected coil of a motor M1 is connected to the positive side DC line of the second inverter.

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 effectively control higher harmonic in controlling a motor. SOLUTION: For an error of target currents i dr , i qr and i d , i q of d and q axes, each is multiplied by K pe to calculate a proportional term. For an error of target currents i dr , i qr and i d , i q of d and q axes, integration is executed and each is multiplied by K ie to calculate an integrated term. The result of integration about other axes are fed back, before respective integrators. In other words, the integration value of an integrator for q-axis is fed back and added to an error before the integrator of d-axis; while before the integrator of q-axis, the integration value of the integrator for d-axis is fed back and subtracted from an error. By providing an interference term for the integration term such as this, PI control on ef axis is appropriately performed on dq axis, with no individual coordinate conversion required for a variable.

摘要： PROBLEM TO BE SOLVED: To provide a rotary electric machine in which a size reduction and a high performance are realized by improving a cooling method.
SOLUTION: In the rotary electric machine, assuring of a magnetic path by the deflection of a magnetic flux line 25 and enlarging of a region 26 which can be cooled are realized by forming a stator core 23 of a dust core material and adding a collar-like additional region 23a to this stator core 23. The reason why such a constitution is formed is because since a loss heat is generated in response to a magnetic flux in the stator core 23 and simultaneously the heat is added as the current loss of the stator coil 22 itself at the place where the magnetic flux in the stator core 23 is generated around a stator coil 22 from the stator to the magnet of a rotor, it is desired to set a refrigerant channel 26 in the region which surrounds the magnetic flux in the stator core 23. In other words, the stator core 23 is suitable to have the refrigerant channel 26 in the interior or the front surface of the stator core of the region which is not interfered with the dense part the magnetic flux line 25 generated with the stator coil 22, and passing through the interior of the stator core 23.

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.

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.
