“…Let VX1, VY1, VZ1 are the reference sinusoids of Inv-I and VX2, VY2, VZ2 are the reference sinusoids of Inv-II shown in equations (3) and (4) respectively. To generate the various PWM techniques proposed in this work are obtained by phase delaying the Inv-II reference voltages by 180 ο with Inv-I voltages as reference [12].…”

This article proposes the space vector based decoupled centric and non-centric PWM techniques for open-end winding induction motor drive. To make the proposed configuration, 2-coventional inverters are fed on either side of open-circuited stator winding of induction motor. Therefore three level output is achieved. To obtain the control pulses for inverters in the proposed configuration reference sinusoids are used. All the proposed PWM techniques use the equal switching frequency. To obtain the validation for the proposed work various theoretical and simulation analysis is carried out using v/f control and the corresponding output voltage is verified experimentally using 1HP asynchronous motor.

“…In order to improve the service quality of the DSIM and ensure their control in different industrial applications with higher reliability, this kind of machine is proposed to be used with the topology of open stator windings, so the machine is no longer a DSIM but it is a dual Stator open-end winding IM (DOEWIM) [7][8][9][10]. Under this new configuration, it is necessary to control the machine using four three-phase voltage systems with specific shift phases between the four power voltage systems to ensure the elimination of the common-mode voltage which is considered one of the inherent characteristics when high frequency DC/AC converters are used to ensure their control [11,12] such as the bearing currents and shaft voltages, which leads to rapid failures of machine bearings and shafts. On the other side due to the use of two inverters from each side of the both windings, the voltage applied to each phase will be seen as multi-level voltage, hence the quality of applied voltage will be improved [7,8,[13][14][15].…”

The present paper deals with a comparative study of the Sliding Mode Control (SMC) technique application on three-phase Dual Star Induction Motor (DSIM) topology and the Dual Open-End Winding Induction Motor (DOEWIM). Where, in these two topologies the Space Vector Pulse Width Modulation (SVPWM) has been used for the control of the two two-level inverters and the four two-level inverters, which have been used to power the two motors under application respectively. The main objective of this study is to demonstrate the higher performances of the DOEWIM under the application of SMC combined with SVPWWM, which aims to overcome the main drawbacks faced when using the conventional topology DSIM in industrial applications. Especially in terms of decreasing the harmonics content in the stator current, reducing the overall ripples of the developed electromagnetic torque, the elimination of the common mode voltage and increasing the robustness against the load torque variation and speed reverse. The obtained simulation results show clearly the main advantages of using the topology of DOEWIM compared to the DSIM topology which present a very promising application especially in heavy industrial requiring high power motors.

This paper focuses on the application of the direct torque control based on space vector modulation (DTC-SVM), combined with the input–output feedback linearization (IOFL) technique on a three-phase dual open-end windings induction motor (DOEWIM) fed by two dual indirect matrix converters. The main aim of integrating the non-linear technique is to overcome the main drawbacks met within the application of the conventional DTC-SVM on dual-stator induction motor (DSIM), such as the torque and flux ripples reduction, the stator harmonics current minimization, and the elimination of the common-mode voltage (CMV). Furthermore, it is proved in this paper that the proposed control on DOEWIN can ensure more flexibility versus speed reverse and variation, load torque changes, and motor parameters variation. The obtained results prove the validity of the proposed control on the studied induction motor topology in ensuring the main aforementioned advantages compared to the conventional DTC-SVM control on DSIM, which presents a promising solution, especially in industrial applications in which high-power motors are required.
