The performance improvement of multilevel inverters has attracted the attention of researchers. The conventional topologies of multilevel inverters require many power-electronic switches which leads to a significant amount of energy being lost as a cause of high-frequency switching. Hence, the trade-off between the losses occurring in the switches of the converter and the efficiency has introduced the concept of reduced component count new multilevel inverter topologies. This paper proposes a modified single-phase inverter, a development of a conventional H-bridge structure. The proposed structure can generate a 15-levels of single-phase voltage output. The proposed inverter is simulated using MATLAB/Simulink software. A simple PWM strategy i.e., Selective Harmonic Elimination is employed to eliminate the lowest-order significant harmonics. Harmonic elimination and THD minimization are nonlinear problems that can be effectively handled by metaheuristic approaches. In this paper four metaheuristic techniques i.e., Teaching Learning Based Optimization, Flower Pollination Algorithm, Modified Particle Swarm Optimization & Invasive Weed Optimization are implemented to obtain the switching angles of the SHE scheme for THD minimization and IWO beats the output of others.
