Space-vector Based Equal Switching Strategy for Three-level Open-end Winding Induction Motor Drive
##plugins.themes.academic_pro.article.main##
Abstract
This paper proposes a new space-vector based pulse width modulation strategy for a three-level openend winding induction motor drive. The proposed method incorporates both the clamping and switching duties of the inverters within every 60o span of the rotation of the reference space vector.The proposed scheme neither requires sector identification nor lookup tables for the generation of the gating pulses. The switching pattern adopted in the present work ensures equal clamping duty and switching duty for both the inverters which are electrically isolated from each other to suppress the zero sequence currents. The switching strategy ensures the usage of all the clamping states thus making the drive system possible for maximum utilization of the switching resources. The proposed strategy is simulated using MATLAB/Simulink and experimentally validated using dSPACE.
