    • PROBLEM TO BE SOLVED: To properly control the operation of a converter in rectangular waveform voltage control for balancing torque control performance and efficiency in a control device of a motor which is so constituted as to allow variable control of a DC-side voltage of an inverter by using the converter. SOLUTION: When a voltage phase ϕv required by rectangular waveform voltage control becomes larger than a boosting determination phase, a boosting request is issued to the converter. When the necessary torque of the motor is large, since the DC-side voltage VH of the inverter is set relatively high, and accordingly a boosting rate is set high. When the boosting rate is large, since the boosting determination phase is set low (ϕ0), a high torque can easily be secured by boosting the DC-side voltage VH in an early stage, and thus the torque control performance is improved. On the other hand, when the boosting rate is small, since the boosting determination phase is set high (ϕ2), the converter can be operated for a long period of time at a non-boosting mode low in switching loss.

    • 要解决的问题:为了在电动机的控制装置中平衡转矩控制性能和效率,以矩形波形电压控制来适当地控制转换器的操作,该电动机的控制装置被构造成允许直流侧电压的可变控制 的逆变器。

      解决方案:当矩形波形电压控制所需的电压相位φv变得大于升压确定阶段时,向转换器发出升压请求。 当电动机的必要转矩大时,由于逆变器的直流侧电压VH设定得比较高,因此将升压速度设定得较高。 当升压速率大时,由于升压判定相位设定为低(φ0),因此能够通过在早期阶段升压直流侧电压VH来容易地确保高转矩,从而提高转矩控制性能。 另一方面,当升压速率小时,由于升压判定相位被设定为高(φ2),因此转换器能够在非升压模式下以低开关损耗的方式长时间运转。 版权所有(C)2011,JPO&INPIT

    • PROBLEM TO BE SOLVED: To properly control the operating state of a converter in square-wave voltage control so that torque controllability and efficiency are balanced in motor control equipment so configured that it can variably control the direct current voltage of an inverter by the converter. SOLUTION: When the voltage phase ϕv requested in square-wave voltage control becomes higher than a boosting determination phase, a boosting request is issued to the converter. When the required torque of a motor is large, the boosting determination phase is set low (ϕ0). Therefore, high torque can be easily ensured by early boosting the direct current voltage of the inverter. As a result, torque controllability is enhanced. When the required torque of the motor is small, the boosting determination phase is set high (ϕ1). Therefore, the converter can be operated for a long time in non-boosting mode in which switching loss is low. COPYRIGHT: (C)2010,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a vehicular motor control system which suppresses a sharp torque change, in a motor controller executing rectangular wave voltage control. SOLUTION: The controller 30 determines whether or not to cause a voltage converter 12 to carry out voltage conversion operation, based on a phase θ of a rectangular wave voltage supplied from an inverter 22 to a motor generator MG2. The controller 30 keeps the voltage converter 12 from carrying out voltage conversion operation and causes the converter 12 to supply a voltage from a battery B1 directly to the inverter 22 until the phase θ of the rectangular wave voltage reaches a threshold. Once the phase θ of the rectangular wave voltage reaches the threshold, however, the controller 30 causes the voltage converter 12 to carry out the voltage conversion operation to raise a voltage from the battery B1 and supply the raised voltage to the inverter 22.

    • PROBLEM TO BE SOLVED: To secure stability in control, in AC motor control where third harmonics are superposed on an AC voltage command by PWM control in overmodulation mode. SOLUTION: A voltage command generator 240 generates voltage commands Vd# and Vq#, based on deviations ΔId and ΔIq between currents on d- and q-axis. The voltage commands Vd# and Vq# are converted into each phase of voltage commands Vu, Vv, and Vw by a coordinate converter 250 after being corrected for increasing the amplitude of a voltage to be applied to a motor by a voltage amplitude corrector 270. A PWM modulator 260 generates switching control signals S3-S8 for an inverter 14, according to each phase of voltage commands Vu#, Vv# and Vw# where third harmonics are superposed by a harmonic superposition processor 255#. The harmonic superposition processor 255# sets the amplitude of third harmonic components, so that an inflection point caused by the third harmonic components may not occur any more, in addition to the inflection point caused by fundamental wave components (voltage commands Vu, Vv and Vw), in the waveform at the apex of the voltage command.
