In this model, the LCL filter parameters are designed using a matlab script. The calculated LCL parameters have been used in the simulink model to check the performance of the LCL filter and THD content of the voltages and currents. In the simulink model, the voltage at the load bus is regulated with the help of PI controller.
The LCL filter parameters calculated using the script give very good performance.
In the matlab script, the tuning of the PI current controller has also been demonstrated using two techniques. One can check the step response of the tuned PI controllers.
