Multilevel inverters have revolutionized the modern world due to their superior performance in industrial applications as well as research in high-power and medium-power applications. Amongst all the different multilevel inverters the cascaded H-bridge inverter has the simplest topology. This paper introduces a modified level shifted pulse width modulation technique using a sawtooth waveform. The proposed modulation scheme significantly improves power quality performance in terms of total harmonic distortion at lower switching frequencies and modulation indices. The results were validated using MATLAB simulation.
