Power quality improvement of grid connected photovoltaic solar systems using 3 level inverter

Abstract

This paper demonstrate simulation modeling of gridtied SPV systems with a 3 level inverter for power quality improvement using SVPWM. To extract maximum power MPPT is used. Three level inverters are used in high power and high voltage application with reduced harmonic contents. The grid tied PV system using three levels inverter has less harmonic contents as comparison of the conventional system or without a three level inverter. The simulation study reveals that the system with three-level inverter using the SVPWM technique generates less THD compared to the conventional system.
