AbstractMultilevel inverters (MLI) have become an integral component in many industrial applications including drive systems and distributed generation grid integrated systems. Efficient and cost-effective MLI topologies are required to enhance the performance of industrial systems. In the present work, an asymmetric double H-bridge MLI is proposed, which incorporates and enhances the attributes of a modified T-type converter and produces a superior output voltage waveform with the lesser component requirement. The proposed MLI can generate a 15-level output. An extendable generalized topology (cascaded) based on the proposed configuration has also been proposed. The topology is compared with recently introduced MLI topologies based on various performance parameters, and results are presented. The output voltage control is achieved using nearest level control which is a low switching frequency modulation technique for lowering the switching losses in the inverter. The hardware is realized, and performance is evaluated under different dynamically changing loading conditions.
