In a rotary electric system, a controller works to turn high-side and low-side switching elements of first and second multiphase inverters on and off to thereby cause: the first multiphase inverter to intermittently supply a first phase current to the first star-connected multiphase stator windings per phase to charge first electromagnetic energy in first star-connected multiphase stator windings per phase, the first electromagnetic energy charging a capacitor; the second multiphase inverter to intermittently supply a second phase current to the second star-connected multiphase stator windings per phase to charge second electromagnetic energy in the second star-connected multiphase stator windings per phase, the second electromagnetic energy charging the capacitor. The first phase current for each phase and the second phase current for a corresponding one phase have a predetermined second phase difference from each other, and the first phase difference is matched with the second phase difference.
