Abstract

This project is describing the recently introduced Proportional Resonant (PR) controller and its performance in the application of 7-level multilevel inverter controller system. The performance of the PR controller is [u2]measured based on the ability of the controller to reduce the harmonic distortion in the inverter system with non-linear load connected at the output of the inverter. This is because of the ability of the PR controller system to have additional selective harmonic compensator. In this project, a new topology of 7-level multilevel inverter is used to prove the efficiency of this topology to provide a symmetric 7-level multilevel inverter with has low Total Harmonic Distortion (THD) due to the reducing of the number of switches used in the inverter circuit. This project consists of the simulation process of the PR controller for symmetric 7-level multilevel inverter with non-linear load. The system is then also been implemented in a hardware setup with the application of Texas Instrument (TI) C2000 microcontroller as the controller of the inverter circuit. The simulation and the downloading process of the PR controller system to the microcontroller is done by using MATLAB/Simulink software[u3]. The result of the multilevel inverter simulation in MATLAB/Simulink shows that the implementation of the PR controller in the inverter system reduce the total harmonic distortion cause by the system load and the harmonic distortion form the inverter system itself. The hardware result shows that the PR controller system is applicable and functioning.
