Multilevel Inverter by using Switching Capacitor in PV Grid

In this paper, we are using multilevel inverter by using switching capacitor for PV grid. Now a day’s multilevel inverters have become more popular over the years in electric high power application with the promise of less disturbances and the possibility to function at lower switching frequencies than ordinary two-level inverters. So by cascading multilevel inverter the output voltage will be increases. By using multilevel inverter the cost will be less. It will be required less space. Modulation strategies, component comparison and solutions to the multilevel voltage source balancing problem will also be presented in this work. By using the multilevel inverter we can reduce the total harmonic distraction compare to the other sources in PV grid for DC to AC converter. The proposed method is simulated in Matlab Simulink.
