    • 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.
    • 电机控制系统包括:电源; 转换器 逆变器 交流电动机; 以及通过转换器和逆变器的操作控制,以正弦PWM控制,过调制控制和矩形波控制中的任一种驱动电动机的控制单元。 当电动机在dq坐标平面上的电动机电流的当前矢量变为与电动机转矩(T2)相对应的电流相位时,控制单元启动转换器的升压操作,在此电动机转矩(T2)开始之前和之后系统损耗相等 升压操作,而控制单元将从电源提供的直流电压提供给逆变器,而不用加紧。 通过转换器的直流电压,在电流相位为最佳电流相位的状态下执行电动机的矩形波控制。
