5. SIMPLIFIED TRANSFORMER BASED MULTILEVEL INVERTER TOPOLOGY FOR RENEWABLE ENERGY APPLICATIONS

As renewable energy sources are playing an important role in development of grid and reducing the pollution of environment but it is polluting the electric power. There are number of power quality issues which are introduced in system due use of switching devices. The renewable energy sources are associated with fundamental framework with the assistance of force electronic gadgets. Also, power hardware gadgets impacts as force quality issues. Consequently to limit the force quality issues happening because of general inverter geography can be diminished utilizing progressed geographies of staggered inverter . This work focuses on developing a nine level inverter having a single transformer and reduced component numbers. An optimization of the number of transf ormers and their turns ratio for a given number of voltage levels resulting in the least number of switches is analysed by designing hardware.
