Cross-connected Multi Level Multi Input Inverter for Low Harmonics Operation

Multilevel inverter performance is up scaled dramatically since it has the potential of reducing passive filters, increasing efficiency and power density. With more confining regulations regarding harmonic emission, more levels are required to allow output filter less operation. This paper proposes a multi input multilevel (thirteen level) inverter which comprises the promising features of low harmonics at its output voltage and current. This topology requires minimum number of switching devices for a given number of levels.
