Abstract
ABSTRACT Multilevel inverters (MLIs) have gotten a lot of attention recently in the power industry because of their efficiency. The application of MLI in photovoltaic (PV) systems to improve power quality and performance has grown dramatically. An innovative, low-component-count 5-L boosting inverter interfaces a single-stage grid-tied PV system with a closed-loop control method in this research. The proposed MLI is put to the test using a 2.1 kW PV system. This technique guarantees optimum power monitoring, DC link voltage balancing, appropriate MLI operation and injection of clean sinusoidal grid current. The suggested system’s outcome is tested by Matlab/Simulink.
