“…However, the configuration has several limitations. It takes a greater number of seriesconnected cells to increase the dc-link voltage, 37 equality of charge inside the cell is too slow, [38][39] removal/isolation of faulty cell reduces dc-link voltage magnitude. The isolation of the cell disconnects the corresponding row batteries from the dc link.…”

This study introduces a novel switched-capacitor (SC) inverter with a simple architecture. The proposed topology synthesized a 13-level voltage waveform with a boosting factor of six. The unique features of the proposed topology are the self-balancing property of capacitors voltage, high boosting factor, least cost function, lower peak inverse voltage, and lower per-unit total standing voltage. A brief analysis of the circuit description, operating principle, the modulation scheme has been presented. The proposed topology's advantages over the existing topologies have been demonstrated through comparative investigations. Finally, the simulation and experimental findings have confirmed the feasibility and dynamic performance of the suggested topology.

“…In recent literature, the common-ground-type inverters have seen evolution in terms of their simultaneous achievement of 5-level voltage generation and double voltage gain [17]- [19]. Further enhancement in the voltage levels generation, such as 7-level and 9-level topology is also presented in [20] (Fig. 1(i)) and [21] (Fig.…”

Recently, inverters with a common ac and dc ground are gaining significant interests due to their zero common-mode voltage that made them particularly attractive for the solar photovoltaic (PV) application. However, the dc source current of the existing topologies is discontinuous, and their voltage gains are limited. This paper proposes a novel common-ground-type boost inverter that achieves continuous dc source current with significantly enhanced dynamic voltage gain. It consists of one boost inductor, four capacitors, nine power MOSFETs and two power diodes. Voltage-boosting and generation of 9-level ac voltage are achieved concurrently within a single-stage operation. The operation of the proposed CGT-9L-BI inverter is analyzed. Simulation and experimental results are presented for validation.

“…The topologies proposed in Siddique et al 16 and Sun et al 17 have similar stress on switches but Siddique et al 16 uses 12 semiconductor switches which is lesser than 16 switches in Sun et al 17 The seven‐level SCMLI with a single dc source discussed in Siddique et al 18 has 11 IGBT along with two capacitors. Some more SCMLI structures with higher voltage gain are proposed in previous works 13,19–29 . In Chen et al, 29 an SCMLI with a common ground has been discussed for PV applications.…”

Multilevel inverters (MLI) play a key role in various medium voltage and high power industrial applications. This paper proposes a triple boost multilevel inverter (TBMLI) comprising switched capacitors. The special features of the proposed circuit are three times boosted output voltage, reduced voltage stress on switches, and the presence of a single dc source. Moreover, the self‐balancing in the capacitors voltage which eliminates the need of auxiliary control circuitry and reduced number of overall components also add to the salient qualities of proposed MLI. The simulation has been done using MATLAB/Simulink, whereas the loss analysis, describing the distribution of the various power loss, has been completed with the help of PLECS software. The proposed topology has a maximum efficiency of 98.3%, whereas the THD in output voltage is 13.65%. The proposed MLI is experimentally investigated to see its performance. A comparison has been conducted to assess the proposed MLI on various parameters.
