This paper aims to extend knowledge about the performance of Multicarrier Based Level Shifted Pulse Width Modulation Using Symmetrical Cascaded H-Bridge Multilevel Inverter. Multilevel Inverters are having more importance in renewable energy applications. Multilevel inverter utilization has been increased since the last decade due to the drastic improvement in the harmonic profile and increased power rating of MLI made them highly popular and high-power applications. Due to the abilities to synthesize waveforms with better harmonic spectrum these inverters are suitable various High-Voltage and High-Power Applications. Asymmetrical type Multilevel Inverter is used for reducing the number of DC sources, Gate Drive Circuits and Bridges. Among the carrier-based pulse width modulation (PWM) techniques, phase-shifted PWM(PS-PWM) is preferred for cascaded H-Bridge (CHB) Multilevel inverters.
