ENHANCING THE PERFORMANCE OF A PHOTOVOLTAIC-FED MULTILEVEL INVERTER USING A PI HYSTERESIS CONTROLLER

In recent years, power quality has become almost as important in the renewable energy sector. Much of today's research is focused on resolving issues. These issues are related to a voltage (sags, swells, distortions, and imbalances), system response speed, harmonics, ripples, Electromagnetic Interference (EMI). Many researchers have recently been working various controllers address articles primarily that arise result time, torque ripples. This study will be used improve performance photovoltaic (PV) fed multilevel inverter. field systems, played critical role. Proportional (P), Proportional-Integral (PI), Integral Derivative (PID), Fractional Order PID (FOPID), (IOPID) systems quality. this study, PI controller measured, analyzed, compared hysteresis controller. Existing methods make use photovoltaic-fed inverter, boost converter, proportional-integral (PI) As load, three-phase induction motor used. A place traditional proposed system. For Controller, Experimental Hardware prototype model designed validated. Simulation designs for existing carried out using MATLAB Simulink, results noted verified. Keywords: controller, Multilevel Inverter (MLI), ripple reduction, Photovoltaic module.
