    • A system is provided for controlling two AC machines. The system comprises a DC input voltage source that provides a DC input voltage, a voltage boost command control module (VBCCM), a five-phase PWM inverter module coupled to the two AC machines, and a boost converter coupled to the inverter module and the DC input voltage source. The boost converter is designed to supply a new DC input voltage to the inverter module having a value that is greater than or equal to a value of the DC input voltage. The VBCCM generates a boost command signal (BCS) based on modulation indexes from the two AC machines. The BCS controls the boost converter such that the boost converter generates the new DC input voltage in response to the BCS. When the two AC machines require additional voltage that exceeds the DC input voltage required to meet a combined target mechanical power required by the two AC machines, the BCS controls the boost converter to drive the new DC input voltage generated by the boost converter to a value greater than the DC input voltage.
    • 提供一种用于控制两台交流电机的系统。 该系统包括提供DC输入电压的DC输入电压源,升压指令控制模块(VBCCM),耦合到两个AC电机的五相PWM逆变器模块,以及耦合到逆变器模块和 直流输入电压源。 升压转换器被设计为向逆变器模块提供具有大于或等于直流输入电压值的新的直流输入电压。 VBCCM基于来自两台交流电机的调制指数生成升压指令信号(BCS)。 BCS控制升压转换器,使升压转换器响应于BCS产生新的直流输入电压。 当两台交流电机需要超过满足两台交流电机所需的组合目标机械功率所需的直流输入电压的额外电压时,BCS控制升压转换器将升压转换器产生的新的直流输入电压驱动到一个值 大于直流输入电压。

    • Methods, system and apparatus are provided for controlling third harmonic voltages when operating a multi-phase machine in an overmodulation region. The multi-phase machine can be, for example, a five-phase machine in a vector controlled motor drive system that includes a five-phase PWM controlled inverter module that drives the five-phase machine. Techniques for overmodulating a reference voltage vector are provided. For example, when the reference voltage vector is determined to be within the overmodulation region, an angle of the reference voltage vector can be modified to generate a reference voltage overmodulation control angle, and a magnitude of the reference voltage vector can be modified, based on the reference voltage overmodulation control angle, to generate a modified magnitude of the reference voltage vector. By modifying the reference voltage vector, voltage command signals that control a five-phase inverter module can be optimized to increase output voltages generated by the five-phase inverter module.
    • 提供了在过调制区域中操作多相机时控制三次谐波电压的方法,系统和装置。 多相机可以是例如矢量控制电机驱动系统中的五相机,其包括驱动五相机的五相PWM控制逆变器模块。 提供了用于过调制参考电压矢量的技术。 例如,当参考电压矢量被确定在过调制区域内时,可以修改参考电压矢量的角度以产生参考电压过调制控制角,并且可以基于 参考电压过调制控制角,以产生参考电压矢量的修改幅度。 通过修改参考电压矢量,可以优化控制五相逆变器模块的电压指令信号,以增加由五相逆变器模块产生的输出电压。
