SummaryMultilevel inverter is a practical power electronic design that has motivated a great deal of ever‐increasing interest. In this article, a new design of basic module‐based multilevel is proposed. The article conceptualized minimizing the number of power semiconductor devices, losses, and total blocking voltage and hence the cost. The proposed inverter structure consists of both a polarity generator and a level generator unit. To investigate the eminence of the proposed topology, an exhaustive comparative study with other existing topologies is presented. The proposed inverter can be utilized for both symmetrical and asymmetrical configurations. The extended cascaded structure of the proposed topology is discussed for generating a higher level of voltages and five algorithms for asymmetrical configuration are introduced to select input dc voltages. This article presents the operating principle, modulation strategy, total standing voltage calculation, cost function, and losses calculation. The efficacy of the proposed cascaded multilevel inverter has been substantiated experimentally. The proposed structure can be efficiently used in medium‐/high‐voltage applications like electrical drives as well as renewable energy resource‐based grid‐connected systems.

Multilevel inverters (MLIs) are used in a variety of industrial applications in high- and medium-voltage systems. The modularity, high-power output from medium voltages, and low harmonic content are some of the advantages of MLIs. The reliability of MLIs is quite important. The reliability is affected by different kinds of faults occurring in the MLIs. In MLI circuits, switching devices are the most vulnerable components and have a major involvement in all types of faults. As an outcome, it is necessary to take proper corrective action in the event of a fault. This work provides a comprehensive review of different fault tolerant (FT) solutions for MLIs in the event of switch fault. Moreover, various single-phase FT MLI topologies are reviewed, along with their constructional features, merits, and demerits. This work also proposes a comparison approach that integrates novel factors to account for fault tolerance quantitatively. A comparison investigation verifies the effectiveness of the proposed method. The FT operation of an existing five-level FT MLI topology is discussed, simulated, and experimentally verified.
