Applications of cascaded H-bridges with storage systems integrated into the grid.

This paper emphasis the best efforts and technique in reduction of harmonic content of the sinusoidal waveform in ac voltage. This is done by increasing the number of steps. In general, number of bridges are determined by the formula 2N+1=Levels, where N is the number of bridges, which leads to 10 bridges. But this project makes use of 4 H-Bridges. This is achieved by making use of asymmetrical multilevel inverter of different voltage source. Also the use of PWM is eliminated, which further reduces the harmonic content in the waveform.
