A Novel Nine and Seventeen-Step Multilevel Inverters with Condensed Switch Count

This paper presents the design of a new single-Phase 9- and 17-level inverters with sinking the components. The 17-level inverter topology is designed by cascading the two nine-step inverters. The topology produces the complex number of output voltage levels with high reliability and reducedtotal harmonic distortion. We develop numerical modeling of the converters using MATLAB/Simulink block sets, and we realize experimental prototype in a laboratory-scale model using digital processordSPACE RTI 1104. Set of experimental and numerical results are provided in this paperwork to ensureand validate the feasibility as per IEC standards. Proposed inverters are well apt for low/high voltage renewable and hybrid electric vehicle applications.
