摘要：
To provide a motor control apparatus that uses an inverter to drive an AC motor and hybrid automotive control apparatus adapted to drive an AC motor by use of an inverter while reducing torque pulsations during switching from PWM driving to rectangular-wave driving.The motor control apparatus 100 has a PWM driving mode in which to input a PWM signal to the inverter 8 and perform PWM driving of the AC motor 4, and a rectangular-wave driving mode in which to input a rectangular-wave signal to the inverter 8 and perform rectangular-wave driving of the AC motor 4. For switching from the PWM driving mode to the rectangular-wave driving mode, a driving-pulse switching block 140 performs the switching process within a maximum pulse-width range of high-level or low-level pulses developed in the PWM driving mode.
