The proposed work is a novel single-phase 11-level multilevel inverter having reduced component count. The proposed configuration is an attempt to visualize the assembling of the semiconductor devices and the DC voltage sources in such a manner that the maximum output voltage levels can be generated using minimum component counts. The particular inverter has the capability to double the voltage levels by the addition of one DC source and one semiconductor switch. For triggering the semiconductor switches, level-shifted pulse-width modulation technique is used so that staircase like output voltage waveform is obtained at the inverter output terminals. The proposed inverter requires less number of switching components and DC voltage sources when compared with the most common conventional inverters. The simulation of the proposed inverter is carried out in MATLAB/Simulink environment. The experimental results are used to verify and validate the simulation results.
