A New Seven Level Inverter Topology with Reduced Number of Power Electronic Switches

This paper proposes a new topology of single phase inverter based on an alternative phase opposite disposition switching strategy. A MATLAB/SIMULINK is used to demonstrate the topology. In the proposed work, six switches are needed to achieve 7- level voltage waveform. Therefore, this topology significantly reduces count of power electronics switches to get higher levels. In this study, comparison between proposed work and classical topology is presented in terms of total number of switches used and THD profile. The results of the proposed work are evaluated through simulation in MATLAB.
