Design of multilevel inverter with its study on different configurations and applications

Electrical device that convert direct current to alternate are termed as inverter. It will be interesting to present an inverter to produce a multilevel output that overcomes the conventional inverters. This made the researchers to introduce new multilevel inverter that can be type of cascading or single unit to produce higher output levels across the load. Here a detailed analysis is made to study the types of MLI that can be made using less number of switches and other components in order to make it compact, so that it will be placed in suitable applications. Study reveals that MLI produces higher level with fewer harmonic that can be placed in electrical applications. Also an attempt is made to design a MLI using MATLAB/Simulink with results.
