Modular Cascaded Multilevel PV Inverter Using Distributed MPPT By ANFIS Controller For GridConnected Applications
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 6
Abstract
This paper shows a modular cascaded H-bridge multilevel photovoltaic (PV) inverter for single-or three-stage grid associated applications. The modular cascaded multilevel topology enhances the effectiveness and adaptability of PV systems. To acknowledge better usage of PV modules and boost the solar energy extraction, an appropriated maximum power point tracking control plan is connected to both single-and three-stage multilevel inverters, which permits autonomous control of each dc-link voltage. For three-stage grid associated applications, PV mismatches may present unequal supplied power, driving to unequal grid current. To comprehend this issue, a control plan with modulation compensation scheme is likewise proposed. An exploratory three-stage seven-level cascaded H-bridge inverter has been manufactured using nine H-bridge modules (three modules for each stage). Each H-bridge module is associated with a 185-W solar panel. Simulation and, experimental results are introduced to confirm the practicality of the proposed approach.
