Summary:This paper presents a cascaded H-bridge multilevel inverter that can be implemented using symmetrical topology. A multilevel inverter is a power electronic device built to synthesize a desired AC voltage from several levels of DC voltages. Multi level inverters have been an important development in recent years. Owning the capability to increase the power quality delivered to the load for high performance applications, the power quality improvement achieved by reducing the harmonics presented at the output voltage of the inverter. The Total Harmonics Distortion (THD) presented at the output phase voltage of the inverter measured and compared. Here, the comparative analysis of several carrier control techniques used for harmonic mitigation is done.
