Recent day’s Multi Level inverters are extensively used due to their increased power handling capability, reduced harmonic distortion or content, less prone to electromagnetic interference and low switching losses. The different multilevel inverter topologies have drawn significant interest in power industries because it can provide high power for the higher power application. The paper deals with implementation of single phase 5 Level inverter using POD PWM technique. The proposed technique for MLI able to generate 5 level output with reduced components as compared conventional topology. POD technique is a Level Shifted scheme where single carrier wave and two sinusoidal waves are used for pulse generation, which is applied to cascaded H-bridge multilevel inverter. The entire work is designed and implemented using software tool MATLAB/Simulink and complete THD analysis is done.
