Abstract

This paper deals with a 21-level asymmetrical voltage inverter with a reduced number of switching components and isolated DC sources. A brief description of the used multilevel inverter is provided, including the circuit configuration and control signals. A pre-calculated switching technique is implemented where the inverter performance is achieved throughout a parametric analysis (THD and fundamental component amplitude). Therewith, selected simulation results are shown to discuss the output voltage and current for different RL-loads and modulation index. The computed current and load voltage signals show a reduced THD that is varying in the permissible limits.
