A REVIEW ON THREE PHASE GRID CONNECTED PV SYSTEM USING THREE LEVEL CASCADED H BRIDGE MULTILEVEL INVERTER

In the recent trend of using green energy, grid connected Photovoltaic (PV) systems are getting more popular. This paper aim to review on, multilevel inverter based single-stage grid connected photovoltaic system based on cascaded three-level inverter is carried out using MATLAB/Simulink. The inverters are controlled using hysteresis current controller for which the synchronizing reference currents are generated using d-q theory. The maximum power is extracted from the PV array under varying environmental condition. The cascaded three-level inverter based grid connected PV system is simulated for injecting active power produced by the PV array under varying solar insolation.
