Abstract

This paper introduces on application of regular-based binary multiplier: RBM switching technique with multi level inverter to control induction-motor speed. Various form of 8-bit RBM signal are generated and choppered with the multi level-inverter output voltage whose switching angle is provided for determining amplitude of fundamental frequency and eliminating unrequired low-order harmonics. Objectives of this switching technique is improvement of the inverter output signal in term of total harmonic distortion voltage reduction (%THD) while controlling the motor. Such motor´s efficiency and performance are improved while voltage to frequency ratio is maintained constantly for stable torque during control
