“…A dual stator induction motor (DSIM) has the edge over other multi-phase motors, i.e., it cancels out the pulsating even harmonic torque components from the individual stator due to opposition when the stator set is supplied from a six-phase inverter and also mitigates the odd harmonics component. Furthermore, DSIM requires less coil insulation and offers low stator resistance and leakage reactance than its three-phase counterparts, reducing the capability to restrain the stator harmonic currents [14,15]. Also, the newly developed model allows the adaptation of volts/hertz control [16] and different modulation techniques to mitigate the harmonics and torque ripple with soft switching of the inverter switches [17].…”

In recent years, multi-phase multilevel inverters (MLIs) with different topologies have been used in various drives due to the potential benefits of multi-phase, over three-phase, in industrial applications.In this paper, performance analysis of five-level cascaded H-bridge multilevel inverter (CHB-MLI) using a new in-phase disposition (IPD) multicarrier pulse width modulation (PWM) technique for harmonic mitigation is presented. In the proposed work, MLI is also implemented with phase disposition (PD), phase opposition disposition (POD), and alternate phase opposition disposition (APOD) PWM techniques. The Matlab/Simulink platform is used to model the proposed topologies. Results obtained from the simulation are compared with the proposed IPD topology. The analysis of resultsshows that the proposed topology mitigates the current and voltage harmonics to 1.7% and 6.15% and increases the system's efficiency with reduced power loss. Finally, the system efficacy is validated by the real-time digital simulator Opal-RT OP4500.
