Abstract

The conversion of DC to AC has emerged as a vital technology in present electrical scenario. Voltage source inverters are basically categorized on the basis of output waveform configuration of voltage. The multilevel inverters (MLIs) are considerably emerging with enhanced importance and performance with modern topologies overcoming the shortcomings of classical topologies. In addition to the advantage of reduced component count associated with MLIs, few more performance characteristics (such as fault tolerance capability, charge balance control etc.) play a very key role in the practical implementation of multilevel dc-ac conversion. A structure obtained from hybridization of diode-clamped and T-type topologies is discussed in this paper. The entire mathematical model of the proposed topology is presented. The analysis on the applicability of source-symmetry has been carried out. The performance of the proposed topology has been analyzed through the simulation based results carried out in MATLAB/Simulink.
