This paper presents a study of seven-Level Cascaded H – bridge (CHB) Inverter. Advantages of CHB inverter are low harmonic distortion, reduced number of switches and suppression of switching losses. They typically synthesize the stair –case voltage waveform (from several dc sources) which has better harmonic spectrum. This paper targets to outspread the information about the working of seven level Cascaded H-Bridge MLI topology with DC/DC Boost Converter for constant DC Source. The output voltage is the sum of the voltage that is generated by each bridge. The switching angle employs Sinusoidal Pulse Width Modulation technique. With this method THD is curtailed. This configuration incorporates Boost Converter in the input side which augments the fundamental output voltage. It also has output filter and thus resultant wave is nearer to the sine wave. Outcomes are verified and observed that yields efficiency around 82%.The analysis of proposed topology has Intended successfully by using MATLAB/Simulink.
