Abstract
The paper presents a new generalized topology-based single-phase cascaded multilevel inverter with reduced power electronic switches, thereby reducing the driver circuits. A new basic unit is proposed in this paper. In order to generate required voltages at the output, an H-bridge is added in conjunction with the basic unit as the unit provides only positive voltage levels. Owing to the merits possessed by cascaded multilevel inverter such as reduction in switch count, driver circuits, low stresses in voltage and their power quality being high, a basic unit is developed. A comparison between the existing topologies and the proposed topology is presented. The developed cascaded 9-level multilevel inverter topology is validated with both simulations and experimentation.
