ROTARY ELECTRICAL MACHINE CONTROL DEVICE

摘要

A vehicle control device 10 of a rotary electrical machine control device includes an application voltage generation unit that generates a voltage control signal S_b that is used to apply a power supply voltage V1 to a DC/DC converter 24 at a voltage equal to or higher than the power supply voltage V1 or at a voltage lower than the power supply voltage V1; and a voltage command value generation unit that generates a motor control signal S_a that controls a drive motor 11. The voltage command value generation unit performs computation based on overmodulation PWM control as PWM control in the case where the application voltage that is lower than the power supply voltage V1 is applied so as to output the motor control signal S_a having a pulse width longer than a cycle of a PWM carrier.
