Claim Text:
1. A power source control apparatus for a rotating electrical machine, the control apparatus comprising: a plurality of rotating electrical machine systems each of which is constituted by a rotating electrical machine and an energization control device that performs energization control of the rotating electrical machine; a target voltage setting unit that sets a target voltage commonly applied to the plurality of rotating electrical machine systems; a voltage control device that applies the target voltage set by the target voltage setting unit to the plurality of rotating electrical machine systems; an optimum voltage acquiring unit that acquires the optimum voltage of at least any one out of the rotating electrical machine and the energization control device in each of the plurality of rotating electrical machine systems; and a limiting unit that limits the voltage applied to the plurality of rotating electrical machine systems by the voltage control device, wherein the target voltage setting unit sets the target voltage based on a highest optimum voltage among a plurality of the optimum voltages acquired by the optimum voltage acquiring unit, and wherein the limiting unit computes a difference between the plurality of optimum voltages, and limits the voltage applied to the plurality of rotating electrical machine systems by the voltage control device to a value lower than the target voltage when the difference is equal to or greater than a predetermined value.
