    This paper proposes a control mode switching scheme between vector control and constant V/ f control for induction machine (IM) drives for maximum torque utilization in a higher speed region. For the constant V/ f scheme, a smooth transition method from the linear range of PWM up to the six-step mode is applied, by which the machine flux and torque can be kept constant in a high-speed range. Also, a careful consideration of the initial phase angle of the voltage in the transient state of the control mode change between the vector control and V/ f schemes is described. The validity of the proposed strategy is verified by the experiment result for a 3-kW induction motor drives.
