Advanced seven level transformer-less multilevel inverter topology for PV application

In the present trend the Renewable Energy Sources (RES) are the main alternative concept to develop the power generation and it is cheap compared to other sources. The RES (Renewable Energy Sources) like solar energy, wind energy, geothermal energy, biomass, tidal power etc., and here among all these sources of energy solar module is developed with two individual boosts converters are utilized to step-up the voltage with Maximum Power Point P&O (Perturb & Observe) technique. The fundamental concentration of this paper is to present the advanced multilevel competitive inverter topology with reduction in device count is the main merit of this topology which is called Packed U Cell (PUC). The main issue of previously designed multilevel inverter topologies is bulk in complex structures; hence it affects the overall system in terms of cost. Due to the excellent characteristics of Packed U Cell topology there is no need of filter requirement, because of output voltage and current are nearer to sinusoidal. To highlight the merits and performance of this proposed concept was simulating in MATLAB/Simulink.
