The proposed work presents the efficiency evaluation of a six‐phase induction motor drive (SPIMD) using an optimized space‐vector modulation (SVM) scheme for medium/high power applications. An optimized SVM is obtained by resolving 5‐level hexagons into outer and inner 2‐level hexagons. In the proposed work, dual three‐phase inverters are used to drive the SPIMD, by dividing six‐phase into two, greatly reducing the calculation time, complexity, and efforts required in building the space vector control algorithm. Moreover, a comparative efficiency analysis of SPIMD using the proposed and conventionally designed SVM technique implemented with closed‐loop control is presented in this paper. Matlab/Simulink platform is used to simulate the proposed system and a prototype is developed as a proof of concept and tested experimentally to verify the analytical developments. Finally, a total harmonic distortion (THD) based comparative analysis of the proposed, conventional, and carrier‐based modulation techniques is also presented.

This paper presents a modified space-vector pulse width modulation (SVPWM) technique for a five-level inverter that provides complete control over the multiple space-vector voltages of a six-phase inverter. This technique involves splitting six phases into two three-phase five-level inverters connected in parallel. A six-phase induction motor (SPIM) drive with a distributed neutral is considered as the load. This paper also presents a comparative analysis between the proposed and conventional SVPWM inverter-fed SPIM drives. To investigate the analytical developments and voltage limits, MATLAB/Simulink environment was used in this study. A prototype was developed in the laboratory for analyzing the harmonic components of the phase voltages and currents. The efficacy of the proposed technique was validated by means of comprehensive experiments, and the results discussed herein.

“…The axis is fixed within the rotor, which rotates at angular speed (ω r ) to prevent the time change inductance in the output voltage. 19 In a dual three-phase machine, when an appropriate rotating reference axis transformation is applied, referring to stator variable to a common q-d reference axis, then the transformation voltage of the machine in q-d axis is expressed as…”

This paper presents an efficiency analysis of the six-phase induction motor (SPIM) drive using a five-level dual three-phase space vector pulse width modulation technique. A dual three-phase space vector is obtained by decomposing a five-level six-phase space vector into two three-phase space vectors, which greatly simplifies the algorithm. This paper also presents a comparative efficiency analysis of SPIM drive with its three-phase counterpart. As a proof of concept, Matlab/Simulink environment was used to simulate the proposed scheme. In addition, a prototype was developed and tested in the laboratory.Experimental results validate the simulation results to a good degree of satisfaction and verify the correctness of the proposed scheme.
