Abstract

Multilevel inverters (MLIs) are developed to meet medium voltage and high power applications in flexible power systems. The conventional configuration of multilevel inverter requires more switches and has limitation to its wide range application. This paper reports the performed work on 1-phase 7-level reduced switch multilevel inverter (RS MLI) in photovoltaic (PV) system. RS MLI configuration integration with PV system which uses less number of switching components for specified number of voltage output levels as compared to that of conventional multilevel inverter topology. To performed enhanced operation of PV cells and maximize the solar energy extraction an incremental conductance (IC) based maximum power point tracking (MPPT) scheme is used. To improve the quality of RS MLI output parameters mainly total harmonic distortion (THD) and switching losses, selected harmonic elimination (SHE) based genetic algorithm (GA) method is consider for control the gating pulse of PV based RS MLI. This work is performed using MATLAB/ SIMULINK software.
