“…According to Table 4, the TSV of the proposed structure is lower than compared to single-source 17-level structures. Additionally, the structures presented in 25,27 , and 28 need switches with a high-rated voltage because the maximum voltage that can (18) www.nature.com/scientificreports/ be tolerated by some switches in these structures is eight times the input voltage, and this issue can limit their application. At the same time, the MSV of the propsosed structure is half of the maximum output voltage.…”

This paper presents a new structure for switched-capacitor multilevel inverter with octuple voltage gain capability. The proposed inverter utilizes three capacitors, 13 semiconductor switches, three diodes, and an input voltage source to achieve a 17-level output voltage. The switched capacitors naturally achieve voltage balancing without the need for sensors or additional circuits, indicating the ease of control of the proposed structure. To control the inrush current of the switched capacitors, a charge limiting inductor has been utilized in the charging path of the capacitors. This not only reduces the inrush current of the capacitors and the input source current but also enables faster capacitor charging and extends their lifetime. The switches used in the proposed structure can withstand a maximum of 4 times the input voltage value or the half of the maximum output voltage, which is a significant advantage for the proposed structure. A detailed comparison with similar structures is provided to examine the advantages and disadvantages of the suggested inverter. The procedure of self-voltage balancing of the capacitors and the functional modes of the proposed topology has been explained in detail. The proposed structure is suitable for applications such as renewable energy sources transfer to load or grid. The performance of the proposed topology under different conditions is confirmed through simulation in the Matlab\Simulink software and the implementation of the laboratory sample.

“…This issue has caused them to have a high cost factor and are not cost-effective for various applications. The structures presented in 22 , 23 , 25 , and 27 are not single-source and produce 17-level voltage in the case of asymmetric sources. The main challenge of these structures is how to provide DC voltage sources.…”

“…Cascaded full-bridge inverters could be used for multi-level operation of low-voltage power supply. Although DC isolated power supply is affected by partial unbalanced current, resulting in reduced waveform quality [12]. Therefore, a kind of inverter called symmetrical cascade bridge inverter is proposed in this paper.…”

New energy power generation, mainly photovoltaic power generation and wind power generation, is one of the key research topics today. It is found that the grid-connected phase of power transmission is very important in the transmission process after power generation through these two ways. This paper introduces in detail the various stages of power transmission under the background of integrated energy system, mainly photovoltaic power generation and wind power generation as the research object. This paper presents a new grid-connected symmetrical cascade half-bridge multilevel inverter (SCHB) under the background of comprehensive energy and presents a Pulse Width Modulation (PWM) control scheme which can make the inverter output stable multilevel voltage. By this scheme, the voltage of the shunt capacitor is basically unchanged and the multistage voltage output of SCHB inverter is guaranteed. The advantages of the designed inverter are that the whole inverter can be powered by a single power supply and a single inductance, and the number of voltage levels can be controlled because of the use of a small amount of reactive power components. This paper describes the topological results of the inverter and the PWM control scheme of stable output multistage voltage.

In this article, a fault-tolerant Packed U Cell MLI (FT-PUC-MLI) is presented, which utilizes two DC sources with nine main switches and eight redundant switches for creating 7-level across the output. The proposed topology uses phase disposition sinusoidal pulse width modulation (PD-SPWM) for the generation of gate signals. A detailed analysis of the proposed topology is done with respect to efficiency, power loss and total harmonics distortions (THD). A brief comparative analysis in terms of device count, total blocking voltage, post and pre fault efficiency, post and pre fault voltage levels is being done. The proposed topology can tolerate single-switch and multiple-switch failures, thus enabling it to be used for emergency loads. The proposed topology maintains a constant output voltage level in the post-fault period. The simulation of FT-PUC-MLI topology is carried out by using the MATLAB/SIMULINK platform with all possible switch fault combinations and real time simulation is also being done in OPAL RT 4510.
