Abstract: A new configuration of multilevel inverter (MLI) has been presented in this paper requiring fewer power semiconductor switches and driver circuits. The proposed topology has better switch utilisation ratio (SUR) with reduction in inverter price. The circuit functional performance of MLI is validated through suitable simulation and experimental results on a laboratory prototype. The MLI has been considered for 5, 11 and 13-level configurations with different resistive and inductive load combinations. Both equal and unequal dc sources are considered to justify the feasibility of the topology.
