Comparative Analysis of Five Level Inverter for Solar PV Application with PI and Fuzzy Controllers

Abstract A single phase cascaded five level inverter which consists of two full bridge inverters is designed for Solar PV application. Two controllers namely the PI controller and Fuzzy controller are developed for five level inverter and the results are compared in order to achieve the optimized output from a Solar PV system fed inverter. Designing of Capacitor filter is done to reduce the total harmonic distortion (THD) of the output of five level inverter. The proposed system is simulated using MATLAB/SIMULINK and the results are observed, presented and evaluated to find the system with better performance.
