Abstract: In modern days, multilevel inverters (MLIs), which are becoming a feasible technology for a number of applications, particularly FACTS applications, have gained increased attention in research and industry. MLI has a harmonic problem that has a negative impact on some applications, such as producing torque pulsing in grid-connected electric drives, shortening system lifespan and deteriorating efficiency. To solve these issues, different MLI topologies have been investigated. Hence, the various types of MLI topologies are discussed in this paper. To comprehend the critical MLI topology parameters, the relevant knowledge of these topologies is meticulously tabulated. Not only are these setups achieving higher performance to enhance power quality, but they are also lowering losses. This review also offers a thorough analysis of MLI topologies' various modulation methods and control schemes. A comparison based on significant performance metrics, specific technological difficulties, and future directions is also included in this review study.
