STUDY OF ASSOCIATION OF DUAL STATOR WINDING INDUCTION MACHINE WITH MULTI LEVEL INVERTER

The present paper gives a quantitative analysis of an dual winding induction machine supplied by multi level inverters, with taking account an arbitrary displacement between the two three-phase windings sets.  The effect of the inverter level on the motor voltage and current total harmonic distortion is performed. The investigation is particularly extended to the steady state electromagnetic torque, where a significant reduction of the oscillations rate is obtained if such multi level inverters are used. All simulation results are achieved by means of Matlab/Simulink software.The effect of the multi level inverter appears in courant voltage and the torque verified using a relative torque ripple rate.
