  "textContent": "To provide an AC rotary machine controller, a vehicle apparatus, and an electric power steering apparatus which can achieve appropriately reduction of the ripple component of the bus current, reduction of the ripple component of the winding current of each phase, or reduction of the switching loss. An AC rotary machine controller controls an AC rotary machine provided with one set or a plurality of sets of three-phase windings; switches a first control mode, a second control mode, and a third control mode, based on an operating state of the AC rotary machine, for each set; executes a phase current ripple suppression control in the first control mode; executes a bus current ripple suppression control in the second control mode; and executes a switching loss suppression control in the third control mode.",
