Design and Development of Control Scheme for Solar PV System Using Single Phase Multilevel Inverter

Abstract

This paper explores transformer less single phase multilevel inverter. The main objective of the paper are to find the operating voltage or peak power voltage for the pv panel (12v), to reduce the Total Harmonic Distortion level within 5% and to check whether the efficiency is to be increased to a certain level. The peak power voltage is the voltage that can be obtained when pv panel produces maximum power. To obtain this, Particle swarm optimization mppt algorithm is used to find the best value followed by several iterations. Evaluation results show that our model outperforms other models in nearly all metrics.
