“…The total nine‐phase windings are re‐organized as 3 three‐phase groups namely: Group‐I ( X 1 , Y 1 , Z 1 ), Group‐II ( X 2 , Y 2 , Z 2 ), and Group‐III ( X 3 , Y 3 , Z 3 ), where the windings are phase shifted by 120 0 in each group. In addition, the performance of nine‐phase IMD with and without isolated neutrals is given in References 16,18,19 and it is found that the modeling of three isolated neutrals N 1 , N 2 , N 3 eliminates the flow of triplen harmonic currents through the phase windings.…”

“…Thus, the individual phase currents and voltages are also free from 18 m ± 1 (where m = 0, 1, 2, 3…) harmonics. In addition, the machine winding of nine‐phase IMD is organized to have isolated neutrals which eliminates triplen harmonics in the individual phase currents and voltages 18 . As a result, the order of harmonic components that appear in individual phase currents and phase voltages will be 18 m ± 5 and 18 m ± 7 (where m = 0, 1, 2, 3…).…”

The advantages such as better fault‐tolerant capability, less space harmonic content, and requirement of power semiconductor devices with reduced voltage ratings etc., made the multi‐phase induction machines drives (IMD) best desirable for the high power applications. However, as the number of phase increases, the improvement in the LMR of the multi‐phase IMDs is not significant using the conventional SVPWM techniques provided in the literature. To address the above‐mentioned limitation, 18‐sided polygon (octadecagon) based voltage space vector generation for a nine‐phase IMD is proposed in this article without compromising in the torque harmonic profile. Using the proposed octadecagonal voltage space vector generation technique, the LMR of nine‐phase IMD is significantly improved by 26.03%, 24.28%, and 9.15% in comparison to the nine‐phase sinusoidal pulse width modulation, nine‐phase SVPWM and individual hexagonal SVPWM techniques, respectively. Efficacy of the proposed control technique is substantiated using the results obtained from ANSYS Maxwell simulation and experimentation on 5‐hp nine‐phase IMD prototype in the laboratory.

This study investigates the angle of phase shift between interleaved carriers in pulse-width modulation, as an additional design parameter to reduce the DC link stress of a five-phase drive. Several phase shift strategies are studied and defined with a focus on the DC link root-mean-square current. The effect of adjusting the phase shift between interleaved carriers on the DC link stress is analysed and a general mathematical model is proposed to estimate the effect for any phase shift strategy. The trends predicted by simulations and analytical models have been validated through the application of the control algorithm on a five-phase motor drive system.

“…The multiphase induction machine is becoming more and more attractive in several applications as automotive [1], naval [2] and aeronautics [3]. Thanks to the possibility of producing smooth torque by more than one current harmonic, unlike the three-phase machine, the multiphase machines offer more degrees of freedom, especially regarding torque density improvement [4] [5], speed-range extension [6] and faulttolerant operating [7] [8]. This kind of machines is supplied by multiphase inverters for variable speed operations.…”

Multiphase induction machines have the advantage of producing torque under different current harmonics. Theoretically, with some simplifications, the maximum produced torque can be considered proportional to the harmonic winding factor related to the injected current harmonic. However previous work has shown that this theoretical proportionality between the maximum developed torque and harmonic winding factors is not obtained in the case of a five-phase induction machine with eight-poles and fractional-slot tooth concentrated winding. This paper aims to investigate the effect of winding parameters, especially phase number, fundamental polarity and stator slots number, on the torque production in multiphase induction machine under harmonics injection. A comparative study is done between four five-phase winding configurations, with the same geometry and copper volume, under both first and third harmonic injection. Finally, a special 15-phase winding presenting better consistency between maximum developed torque and harmonic winding factors is proposed.
