This work present a closed-loop method is applied to control the multilevel inverter which injects power into the grid. The voltage and current controls are implemented for controlling the system by using Droop control, master slave control and average current sharing control. Among them Droop control techniques is very popular due to better communication and quick response. A Maximum Power Point Tracking control is executed using perturb and observe (P&O) method is employed to control boost converter. A closed loop control method is applied to insert power into the grid using multilevel inverter. DC link voltage control and current control is used to controlling multilevel inverter. The resulting system is able to collect maximum power from the Photo Voltaic system under different operating conditions. To compare all the different types of voltage control techniques and try to find out the best solution of current sharing of different paralleled converters and also smooth operation with microgrid.
