Therefore, a filter is required between the power inverter and the utility grid to ensure quality energy that abides by IEEE standards for grid integration. This paper proposes a 4kW, 400V grid-tied inverter and LCL filter design to interface an array of solar panels to the utility grid. The theory of the two-level, three-phase power inverter and its filter, along with their corresponding designs, is analyzed. Filter selection is discussed, in addition to a filter damping method using a resistor in series. Design, simulation, and experimental tests demonstrate the mathematical theory of the selected LCL filter. 2025-05 Text https://hdl.handle.net/2142/129190 Copyright 2025 Victoria Jeziorczak Electrical & Computer Eng Electrical & Computer Engr University of Illinois Urbana-Champaign M.S.
