    • A control system aims at converting, via a switching circuit, a direct current voltage into an alternating current voltage to be applied to multiphase windings of a multiphase rotary machine to thereby control rotation of the multiphase rotary machine. In the control system, a command voltage determiner determines a command voltage value for an alternating current voltage to be applied to the multiphase windings based on a zero crossing of a line-to-line current and a zero crossing of the amount of change in the line-to-line current. A driving unit drives the switching circuit on and off based on the determined command voltage value to thereby modulate the direct current voltage to the alternating current voltage to be applied to the multiphase windings.
    • 控制系统旨在通过开关电路将直流电压转换成施加到多相旋转机器的多相绕组的交流电压,从而控制多相旋转机器的旋转。 在控制系统中,指令电压确定器基于线对线电流的零交叉和变化量的零交叉来确定要施加到多相绕组的交流电压的指令电压值 线间电流。 驱动单元基于确定的指令电压值来驱动开关电路,从而将直流电压调制为施加到多相绕组的交流电压。
