A novel 7-level reduced switch multilevel inverter with minimum number of switches incorporated with boost converter with photovoltaic system.

Abstract

This manuscript presents the achieved efforts on 1-? 7-level reduced switch multilevel inverter (5S-7L MLI) in PV system. To carry out improved maneuver of PV cells and make best use of the solar energy extraction, a MIC ( Modified incremental conductance) based MPPT with DC-DC boost converter plan is employed. To cheer the quality of 5S-7L MLI output parameters primarily THD and switching losses, SHE PWM (selective harmonic elimination based pulse width modulation) technique is consider for controlling the gate pulse of PV based 5S-7L MLI. The proposed PV based 7-level 5S-7L MLI is compared with other conventional MLI and various existing 7-level reduced switch topologies. This work is performed and results are validated using MATLAB/SIMULINK.
