This article relates different multilevel inverter topologies with PWM techniques and the implementation of level shift PWM techniques to five-level cascaded H-bridge (CHB) inverters. Multilevel inverters are found suitable for high voltage and high power applications as the voltage stress on a switching device gets reduced in it. The output of the multilevel inverter is having low THD which makes them suitable for renewable energy integration and drives applications in industry. In the proposed five-level Cascade multilevel inverter (MLI) phase disposition, phase opposition disposition, and alternate phase apposition disposition PWM methods were implemented. The comparative analysis has been done by using the Simulink platform of MATLAB software and the result validation has been performed through the prototype model. The base of comparison is taken as a THD and ease of implementation. Prototype results were analyzed by using DSO and Power Analyzer.
