Three Phase Modular Multilevel PV Inverter With Distributed MPPT for Grid-Connected Applications
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2017, Vol 5, Issue 1
Abstract
In this paper a three - stage modular cascaded H-bridge multilevel inverter for a grid associated photovoltaic (PV) framework is depicted . To expand the solar energy extraction of each PV string, an individual most extreme power point tracking (MPPT) control plan is connected, which permits the autonomous control of every dc-interface voltage. PV confuses may acquaint uneven power provided with the three-stage framework. To fathom this issue, a control plot with modulation compensession is proposed. The three-stage modular cascaded multilevel inverter model has been constructed. A fuzzy controller is actualized in this venture in the place of PI controller . Every H-bridge module is associated with a 185-W ssolar panel. Simulation results are exhibited to confirm the achievability of the proposed approach in MATLAB/SIMULINK environment.
