The traditional closed-loop current control strategy The three-phase LCL-type grid inverter allows for the generation of grid current with lower harmonic distortion and high power density, this characteristics makes it is widely used in the energy conversion technologies.
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. Keywords—LCL filter; MATLAB/Simulink; connected.
A mathematical model is developed using the power circuit of a three phase grid connected VSI with LCL filter. The three phase power circuit is reduced to a single phase equivalent circuit and the transfer function of the LCL filter derived using the circuit parameters.
The three-phase LCL-filter-based grid-connected inverter (LCL-GCI) is a third-order and multi-variable system, and claiming a higher demand to the control system design.
