In this paper modelling, simulation and control of grid tie PV system using multilevel inverter are described.A 20kW PV system is integrated to grid using 3 level neutral point clamped (NPC) voltage source inverter (VSI). Anmppt control is implemented using incremental conductance (INC) method is employed to control boost converter. Aclosed loop control method is used to inject power into the grid using multilevel inverter. DC link voltage control andcurrent control is implemented for controlling multilevel inverter. The resulting system is able to extract maximum powerfrom the PV system under different operating conditions. The capacitor voltage balance across the inverter is achievedusing SVPWM technique. Control of proposed system is based on synchronous reference frame control algorithm andhysteresis band current control. The effectiveness of proposed system is shown using MATLAB simulation results.
