For the vast majority of power electronic applications operating in the medium and high voltage ranges, multilevel inverters (MLI) have become an absolute need. The introduction of new topologies has rendered the conventional ones obsolete, which has resulted in a multiplication of the capacity to build a greater number of levels using a smaller number of components. Also, the newly developed topologies of MLI employ asymmetrical DC sources to produce the same levels with a reduced number of semiconductor switches. This results in a decrease in capital expenditures and an increase in the system's overall dependability. In a practical sense, asymmetrical direct current sources may be derived from a wide variety of renewable energy sources, such as solar, fuel cell, and wind turbine systems, amongst others. In conclusion, the many newly established methods for modulation play an important role in improving the overall performance of MLI and are thus essential to its success. In this study, a survey for classic and current topologies of MLI is presented, along with a discussion of the benefits afforded by the new topologies.
