    • A motor control system includes: a power supply; a converter; an inverter; an alternating-current motor; and a control unit that drives the motor in any one of sinusoidal PWM control, overmodulation control and rectangular wave control through operation control of the converter and the inverter. The control unit starts step-up operation of the converter when a current vector of motor current of the motor on a d-q coordinate plane becomes a current phase corresponding to motor torque (T2), at which a system loss is equal between before and after starting the step-up operation, while the control unit supplies the direct-current voltage, supplied from the power supply, to the inverter without stepping up. the direct-current voltage by the converter and performs the rectangular wave control of the motor in a state where the current phase is an optimal current phase.

    • A power supply apparatus driving and controlling motor generators (MG1, MG2) includes a battery (10) generating an input voltage (Vb), a converter (110) converting the input voltage into a motor operating voltage (Vm) according to a voltage command value (Vmr), a smoothing capacitor (120) holding the motor operating voltage, inverters (131, 132) receiving the motor operating voltage and driving and controlling the motor generators (MG1, MG2) according to a torque command value (Tref), and a control unit (15) generating the voltage command value and the torque command value. When the motor generators (MG1, MG2) operate in the power running mode, the control unit (15) operates to make the torque command value smaller than an original required torque as necessary so as to allow the sum of electric power (Pm) consumed by the motors and an amount of change (Pc) in stored electric power of the smoothing capacitor (120) caused as the motor operating voltage increases not to exceed an output electric power limiting value (Pcvlm) of the converter (110).
    • 驱动和控制电动发电机(MG1,MG2)的电源装置包括产生输入电压(Vb)的电池(10),根据电压指令将输入电压转换为电动机工作电压(Vm)的转换器 (Vmr),保持电动机工作电压的平滑电容器(120),接收电动机工作电压的逆变器(131,132),并根据转矩指令值(Tref)驱动和控制电动发电机(MG1,MG2) 以及产生电压指令值和转矩指令值的控制单元(15)。 当电动发电机(MG1,MG2)在动力运行模式下工作时,控制单元(15)进行操作,以使转矩指令值小于必要的原始要求转矩,以使得消耗的功率(Pm)之和 通过电动机和由于电动机工作电压增加而导致的平滑电容器(120)的存储电力的变化量(Pc)不超过转换器(110)的输出功率限制值(Pcvlm)。
