Implementation of SOA-SHE Control for Seven-Level Switched Capacitor-Based MLI with Boosting Capability

The standalone photovoltaic system can solve the issue of power requirements for remote places without depending on the grid supply. The inverters play an important role in effectively extracting power from the PV system and integrating it with the load. Switched capacitor-based multilevel inverters (SC-MLI) with a suitable control strategy are popular in these systems. The paper suggests implementing a new nature-based Seagull optimization (SOA) algorithm for selective harmonic elimination (SHE) control for the proposed seven-level SC-MLI. The voltage can be enhanced 3 times utilizing the proposed MLI circuit. The proposed fundamental frequency-based control technique can reduce the total harmonic distortion (THD) more effectively as compared to the conventional particle swarm optimization-based SHE technique. The efficacy of the control technique is verified by SIMULATION in MATLAB.
