Indirect Vector Control of Induction Motor Based on Five-Level Inverter Cascaded H-Bridge Using Space Vector Modulation

Abstract

This paper proposes a Space Vector Modulation for a five level inverter in an indirect vector control of induction motor. Due to their numerous benefits, five-level inverters are becoming more attractive. They generate high quality of the output voltage, offer a reduction in harmonic distortion and they make the system more efficient. The cascaded H-Bridge inverter is chosen in the indirect vector because it needs fewer number of components compared to other topologies of multilevel inverter. Therefore, less cost and complexity. The implementation of space vector control for this five-level inverter is used to improve the system and to compensate the distortion of harmonics. Morever, it can be implemented on any digital signal processor. The simulation results of this proposed system is realized with Matlab/Simulink. The results prove the excellent performance of the proposed system. They show a good response with a minimum of total harmonic distortion.
