LCL Filter Design for Grid Connected Three-Phase Inverter

In this study, LCL filter design was performed by simulating and theoretical analysis detail of a grid-connected system in MATLAB / Simulink environment. Inverters connected to the grid, filter is required as an interface between the inverter and the electric grid. The most effective filter for suppressing of the current harmonics occurring from the switching frequency injected into the grid is the LCL filter. The LCL filter must be designed appropriately to achieve high quality grid currents. LCL parameters are calculated for synchronized operation of the converter and grid. Simulation results were shown that, the LCL filter designed for harmonics has decreased in high degree harmonics in inverter output.
