چکیده مقاله:

In this paper, application of cascaded H-bridge multilevel inverter in DTC-SVM based induction motor drive is presented. Cascaded H-bridge multilevel inverter uses multiple series units of H-bridge power cells to achieve medium-voltage operation and low harmonic distortion. Each H-bridge can be implemented using a dc source, which would be available from fuel cell, batteries or ultra-capacitors. This inverter can be perceived in two arrangements, symmetrical and asymmetrical with equal and unequal dc voltage sources, respectively. The control strategy is based on DTC-SVM technique. In this scheme, first, stator voltage vector is calculated and then realized by SVM method. Contribution of multilevel inverter to the DTC-SVM scheme is led to achieve high performance motor drive. Five-level and nine-level inverter are employed to investigate the considered motor drive. Simulations are carried out in Matlab-Simulink. The results demonstrate the great performance of multilevel inverter in DTC-SVM induction motor drive
