Abstract
To provide an AC rotary machine controller, a vehicle driving apparatus, and an electric power steering apparatus which can reduce the influence of the leakage current generated by the variation of the voltage of winding terminal of each phase by turning on and off the switching devices. An AC rotary machine controller executes, for each set, a flat-top two-phase modulation or a flat-bottom two-phase modulation; generates first comparison pulse wave and second comparison pulse wave; shifts one or both of paired the first comparison pulse wave and the second comparison pulse wave in an advance direction or a delay direction so that a rising timing of one of paired the first comparison pulse wave and the second comparison pulse wave coincides with a falling timing of the other.
