A Single Phase Cascaded Asymmetric Multilevel Inverter Topology

In multilevel inverter, asymmetric configuration uses different values of DC sources which give increased voltage levels at the output with reduction in switching devices. Topology for single phase asymmetric multilevel inverter is proposed in this paper. The simulation results of this topology shows that asymmetric configuration gives more levels at the output compared to symmetric configuration with same quantity of voltage sources and switching devices.In addition, the FFT Analysis shows that THD is reduced to a considerable amount with the asymmetric configuration.
