Comparison between Cascaded Multilevel inverter and reduced switch multilevel inverter
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 5
Abstract
This paper proposes a comparison between cascaded seven level inverter and nine level inverter using Phase opposition and disposition Pulse Width Modulation control scheme. The number of switches used in the cascaded seven and nine level inverter is identified and the Total Harmonic Distortion (THD) between them is compared. As the level gets increased the number of switches gets increased so the reduced switch topology is used with Pulse Width Modulation control scheme. The number of switches used in the reduced switch seven level and nine level inverter topology will be less when compared to the cascaded seven level and nine level inverter. The Total Harmonic Distortion (THD) between cascaded multilevel inverter and the reduced switch multilevel inverter is compared. The results are observed by MATLAB/SIMULINK software.
