The utilization of multilevel inverter in medium and high power applications is increasing for improving the power quality. The multilevel inverter was introduced as a solution to increase the converter operating voltage above the voltage limits of classical semiconductors. The function of the multilevel inverter is to synthesize a desired high voltage from several levels of dc voltages. The multilevel inverters are becoming popular as they have low harmonic contents, better electromagnetic compatibility and lower switching losses. This paper deals with a single phase five level cascaded H-bridge multilevel inverter with R-load. Sinusoidal Pulse Width Modulation technique is used to develop the switching pattern for the five level H-bridge multilevel inverter to reduce the total harmonic distortion at the output. A Pi filter is used to further reduce the total harmonic distortion and improve the power quality. This paper also compares the percentage THD of multilevel inverter with and without filter. It has been shown that the total harmonic distortion in multilevel inverter with filter is less than that in multilevel inverter without filter.
