“…With respect to fundamental idea of MLVSIs we will produce 7 levels of voltage as output by utilizing only a capacitor in parallel and 1 dc source by using modulation techniques. [12]- [13]. Likewise, we can also create more levels of voltage as output using coasted capacitors and 1 dc source by utilizing equivalent control of hardware foe flying capacitor multi level VSI.…”

There is a disadvantage with a two stage switched capacitor module multi level inverter with the end goal the switches of subsequent level like H connect perseveres which are through higher voltage stress. To determine the issue, in this paper, we proposed a module that guarantees pinnacle reverse voltage among all switches which is limited to dc voltage source for cascaded multilevel inverter. This module is called single stage switched capacitor module (S3 CM). Nine voltage levels are created with just a one dc source, two joined capacitors. Thus, quantity of isolated dc sources was fundamentally decreased contrasted with cascaded H-bridge. What's more, voltage gain increase by two is accomplished. A similar investigation averse the ongoing methodology uncovers the proposed S3 CM module accomplishes decrease in number of switches. And furthermore switching states of inverter will be controlled by utilizing closed loop PI controller.

“…These converters featured a less number of switches and less number of DC power supplies, which contributes to reduced weight, volume, and cost [17]. Two new switched‐capacitor MLIs have been suggested in [18, 19] that benefit from lower switches. However, a large number of DC power supplies in theme and high TBV on switches in [18] are disadvantages that cause lower efficiency.…”

In this study, a novel multi‐source switched‐capacitor converter is proposed. In the proposed topology, the capacitor charging is carried out in a self‐balancing form eliminating the need for additional balancing circuits. After that, the design principle of the proposed inverter is discussed in details. A comparison study between the proposed topology and other existing topologies is provided next. According to this comparison, the proposed topology requires fewer components, such as DC power supplies, switches, capacitors, and diodes. Further, the simulation results for 15‐level and 127‐level and the experimental results for a 15‐level inverter are provided. The simulation and experimental results are in close agreement and verify each other.

The aim of this study is to present a new cost effective topology for Symmetric multilevel inverters (SMLIs) configurations, which can generate a great number of output voltage levels with a least of switching devices. The proposed structure contains a novel switched-dc-source (SDCS) sub-module that can produce three positive output voltage levels with a contribution of four equal dc voltage sources, two unidirectional, and one bi-directional power switches. Accordingly, to create a uniform staircase output voltage with multiple levels, the proposed SDCS sub-module is integrated into a new design. Therefore, a new family of reduced switch-count (RSC)-SMLIs is derived, which is capable of generating at least 13-and 15level output voltages using only ten power switches and nine gate drivers. Furthermore, when employing several of the proposed SDCS sub-modules in series, a new generalised RSC-SMLI topology is obtained. Comparisons with prior-art SMLIs structures are done, which also highlights the beneficial potential of the proposed topology. To demonstrate the superior performance of the proposed topology, several simulation and experimental results have been provided.
