Recently there has been growing interest in multi-phase motors and drives due to their potential advantages including lower torque ripple and harmonic currents, better power density, higher reliability and stability. Two commonly used modulation methods space-vector modulation and sine-triangle modulation are proposed for using in multi-phase induction motors. In this paper, the implementation details of producing random switching patterns are presented by using MATLAB/Simulink. The simulation results are shown for three-level five-phase induction motor. Add current harmonics in the sine-triangle modulation based on the result of SVM. Finally, compare their torque ripples and show the further optimized scheme.
