SELECTIVE HARMONIC ELIMINATION SWITCHING STRATEGY FOR BACK-TO-BACK STACKED MULTICELL CONVERTER

This paper purposes the selective Harmonic Eliminat ion Pulse Width Modulation (SHEPWM) strategy for the 17-level Back-To-Back Sta cked Multicell Converter (BTBSMC) to improve the power quality by decreasing the Total Harmonic Distortion (THD). BTBSMC is the better converter to generate the higher number of output voltage levels with lower number of power electronic switches as compared to the other conventional converters. The control used in this paper eliminates the selective lower order harmonics which are adjusted in case of sector modulation control. Resultant theory is used to generate the angles with different modulation index .The simulation results has been carried out using SIMUL INK/MATLAB present the effectiveness of the SHEPWM strategy for the proposed converter
