Abstract

ABSTRACT

Investigation of SVPWM Based Sliding Mode Control Application on Dual-Star Induction Motor and Dual Open-End Winding Induction Motor

“…Furthermore, the DSIM offers in addition to the advantages of induction machines, those of multiphase machines, such as: power segmentation, minimization of torque ripples and rotor losses, reduction of harmonic currents, high reliability against power supply faults and it can be used in high-power applications [3][4][5][6]. 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].…”

Improved DTC-SVM Based on Input-Output Feedback Linearization Technique Applied on DOEWIM Powered by Two Dual Indirect Matrix Converters

“…At the same time, the DSIM offers, in addition to the advantages of induction machines, advantages of multiphase machines, which have been aforementioned. In order to improve the service quality of the DSIM and ensure its control in different industrial applications with higher reliability, the DSIM has been used with the new topology that requires the opening of both stator windings; thus, the machine is no longer a DSIM but it is a dual open-end winding induction machine (DOEWIM) [7][8][9][10]. Under this new configuration, it is necessary to control the machine with four three-phase voltage systems, with phase shifts well-calculated between them so that we can eliminate the common-mode voltage and rid of its several issues, such as the bearing currents and shaft voltages, which leads to rapid failures of machine bearings and shafts [7,8,[11][12][13][14][15].…”
