Abstract: An inverter control device is for a vehicle including: a rotating electric machine that is an in-wheel motor integrated inside a drive wheel and includes a rotor including a magnet portion with a plurality of magnetic poles and a stator including multiphase stator windings without teeth protruding radially toward the rotor; and an inverter electrically connected to the rotating electric machine. The inverter control device includes: a control unit configured to perform PWM control to generate a drive signal for a switching element in the inverter based on a carrier signal and a command voltage in each phase in the overall operating region for an operating point defined by the rotation speed and the torque of the rotating electric machine; and an operation unit configured to operate the switching element based on the generated drive signal.
