Abstract— This paper carves out the design of unity power factor controller for three phase variable speed induction motor drive. SPWM technique is used to improve the power factor of the system to unity and hysteresis controller is used for speed control of the drive. These control techniques lead to a unity power factor seen by the ac supply and minimize the power loss, audible noise, and motor torque ripple. A three level converter-inverter system employing advanced insulated gate bipolar transistors (IGBTs) is used.
