By analyzing the characteristics of photovoltaic inverter, the method of filter designing was provided. Based on the application, a filter used in 100kW 3-level grid connected photovoltaic inverter was designed. Simulation results by MATLAB/Simulink ware evaluated in order to access the performance of designed filter and the quality of the current injected into the grid. The design procedure and the simulation results represent a powerful tool to design an LCL filter in grid connected photovoltaic inverter.
