###### Abstract
By doing away with the end-side H-bridge inverter, the suggested construction ensures that every component can tolerate voltage stress, which is equivalent to the input DC voltage [6; 7]. Both topologies exhibit peak inverse voltage (PIV) within the supply voltage but employ more switches. A single-stage eight-switch SCMLI is proposed in ref. [8], which results five different levels at its output terminal. Despite this, it has the lowest voltage gain, and only a few of its switches are able to sustain high-voltage stress. During the first stage of a two-stage SCMLI, a unipolar multilevel waveform is generated, and then, an H-bridge (or an equivalent) is used to unfold it into a bipolar waveform. The amplitude of the output voltage causes significant voltage stress, which is felt by these H-bridge switches for high-voltage AC power supplies.The structures that are suggested in refs. [9; 10] are examples of topologies that have two stages. The SCMLI structure that was proposed in ref. [9] is an easily expandable one; however, it has a very large component count, and it provides a modest voltage gain while exhibiting a high CF. For instance, the series/parallel SCMLI that was described by [PERSON] et al. [10] is capable of producing 2n + 3 different levels of ac output voltage, where n is the number of SC cells, and each level is comparable to the dc input voltage. In addition, the voltages of the capacitors in this SCMLI are automatically adjusted without the use of any additional balancing circuits or control algorithms. Moreover, it has large TSV and switching components. A seven-level boost-ANPC inverter with eight switches is the subject of investigation in ref. [11], where it is abbreviated as 7L-Boost-ANPC. Compared to the typical multilevel inverter family, the dclink voltage need is lowered byhalf, and both the active and passive components can be scaled back for generalpurpose applications (such as rolling mills, fans, pumps, marine appliances, mining, traction, and grid-connected renewable energy, etc.). An ANPC 7L self-voltage balancing inverter (7L-SVBI) has a high gain and places low voltage stress on the switches. Despite this, they still necessitate a great deal of both active and passive components, in addition to a larger dc link voltage, which is presented in ref. [12]. The input voltage can be increased using the two-stage topology described in refs. [12; 13]. These topologies, however, include HB, which increases voltage stress and switching components. A three-phase active neutral point clamped topology has been devised in recent years [14; 15; 16]. The first attempt to increase the voltage gain of a typical seven-level ANPC by 1.5 was madeby the author in ref. [14]. This was accomplished by suitably integrating a floating capacitor. It is common knowledge that two-stage boosting MLIs, which are excellent choices for photovoltaic power plants, are susceptible to damage as a result of the high voltage stress that is placed on the switches of the second stage. Single-stage boosting MLI, which requires a reduced number of switches, diodes, and capacitors, was proposed in ref. [15] for use in applications related to renewable power generation. For the generation of five different voltage levels, it onlyneeds a single capacitor and nine switches. Additionally, it lowers the voltage stress, which is placed on the switches.Researchers are investigating a novel six-switch five-level boost-ANPC inverter (5L-Boost-ANPC) for generalpurpose applications (such as rolling mills, fans, pumps, marine appliances, mining, tractions, and most notably, grid-connected renewable energy, etc. ), which reduces the dc link voltage requirement to half of conventional 5L-NPC and 5L-FC family, as well as reducing the number of active and passive components [16]. In ref. [17], an MLI with five levels and grid connectivity is introduced.
