    • Methods and apparatus are provided for controlling a boost converter. In one embodiment, the method includes processing an input current command through a plurality of prioritized limiting circuits to determine whether to limit the input current command and limiting the input current command to limit the boost converter when it is determined to limit the input current command. In one embodiment, the apparatus includes an energy source coupled to a boost converter that provides an output voltage responsive to a current command signal. An inverter is coupled to the boost converter to provide multiple phased currents to a multi-phase motor for a vehicle. A controller coupled to the boost converter for providing the current command signal by processing an input current command through a plurality of prioritized limiting circuits and determining whether to limit the input current command to provide the current command signal to the boost converter.
    • 提供了用于控制升压转换器的方法和装置。 在一个实施例中,该方法包括通过多个优先级限制电路来处理输入电流指令,以确定是否限制输入电流指令,并且当确定限制输入电流指令时限制输入电流指令以限制升压转换器。 在一个实施例中,该装置包括耦合到升压转换器的能量源,其提供响应于当前命令信号的输出电压。 逆变器耦合到升压转换器以向车辆的多相电动机提供多个相控电流。 控制器,耦合到升压转换器,用于通过经由多个优先化限制电路处理输入电流指令来提供电流指令信号,并且确定是否限制输入电流指令以向升压转换器提供电流指令信号。
