Modeling and Performance Comparison of two different Hybrid Multi Level Topologies

In medium and high voltage industrial drive applications, hybrid Multi Level Inverters (MLI) have predominant importance. In order to realize hybrid multi level inverters, different topologies have been suggested. The key disadvantages in the realization of conventional hybrid topologies are the requirement of more number of switches per phase and complexity in the design of control signals. This paper brings out the modelling and performance comparison between two different hybrid multi level inverter topologies. The simulation is carried out using Simulink tool in MATLAB software.
