用于控制两台交流(AC)电机的操作的方法、系统和设备
摘要：
本发明涉及用于控制两台交流(AC)电机的操作的方法、系统和设备。提供一种用于控制两台AC电机的系统。该系统包括：DC输入电压源，其提供DC输入电压；电压升高命令控制模块(VBCCM)；五相PWM逆变器模块，其耦联至两台AC电机；和升压转换器，其耦联至逆变器模块和DC输入电压源。升压转换器设计成向逆变器模块提供具有大于或等于DC输入电压的值的新的DC输入电压。VBCCM基于来自两台AC电机的调制指数产生升压命令信号(BCS)。BCS控制升压转换器，使得升压转换器响应于BCS产生新的DC输入电压。当两台AC电机需要补充电压时，其中该补充电压超过满足由两台三相AC电机需要的组合目标机械动力所需的DC输入电压，则BCS控制升压转换器，使得由升压转换器产生的新的DC输入电压驱动成大于DC输入电压的值。
摘要（英）：

The invention relates to methods, systems and apparatus for controlling operation of two alternating current (AC) machines. 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.
