Abstract

This manuscript presents a novel algorithm for Space Vector Pulse Width Modulated (SVPWM) multilevel inverters (MLI) named as Euclidean distance mapping (EDM). The space vector diagram (SVD) of voltage source inverters (VSI) is processed as an image by the EDM-SVPWM technique; which allows us simplified execution of SVPWM for MLI by doing away with sector recognition, sector based complex trigonometric calculations, extra coordinate transformations and the level based dwell times calculations. An unique switching sequence design algorithm is evolved from the EDM technique, by which improvement in the inverter performance with reference to the factors like stator flux ripple over a sub-cycle, total harmonics distortion (THD) of line voltage, line current ripple and distortion factor (DF) is attained. The EDM-SVPWM technique is validated by analytical treatment and experimentation on hardware prototype.
