“…This results in the output voltage being boosted to 19 times that of the input voltage. When contrasted with [76][77][78][79][80][81][82][83][84][85][86][87], the proposed topology [88,89] has a maximum efficiency of 99.06%. Unidirectional switches and DC sources accomplish the maximum output.…”

Due to cutting-edge innovations in industry and academia, research is more centered around multilevel inverters (MLIs), which play a significant role in different high/medium voltage and high-power applications when contrasted with traditional inverters. Relative analysis of the reduced DC source count and switch inverter topologies highlight its significant benefits, which include control complexity, switch count, source count, reliability, efficiency, cost, voltage stress, total harmonic distortion (THD), and power quality. When switched-capacitor technology is deployed, it is seen that with the assistance of 14 switches, a 53 level result is accomplished, and the THD is just around 1.41%, which is kept up with as per the IEEE 519-2014 norms. Whenever cascaded MLI topology is employed, the inversion efficiency is more prominent, and is about 99.06%. Hence, this review focuses on a few of the late-evolved MLIs utilized, and the benefits and drawbacks for different topologies are examined. To assist with current modern research in this field and the decision of the proper inverter for various applications, a novel topology of an MLI can be planned later on. Different setups of MLIs have been exhaustively covered and reviewed.

“…Recently, they have been introduced into renewable energy applications like wind, PV and fuel cells [4].They have also been used in low and medium voltage applications [1,[5][6]. Multilevel inverters consist of a cluster of semiconductors and capacitors, which produces output in the form of staircase voltage waveform [7].The application of switches in these devices allow as the addition of capacitor voltage reaching high voltage level while power semiconductors must withstand only reduced voltage [8][9]. Therefore, they provide improved output, lower electromagnetic interference, lower device stress, reduced size and cheaper [6,[10][11][12][13][14].They also generate smaller common mode voltage reducing stress in motor bearing [15].…”

This paper presents a 5 level T-type multilevel inverter, to improve the performance of the hybrid system and then improved voltage is injected into the grid. Two three level inverter with common emitter and common collector configurations are combined to obtain a five level inverter. PV and wind energy is used as a source of energy to the five level T-type MLI. It has advantages such as low switching losses, lesser THD, less filter requirement and superior output quality when compared to 3-level T-type MLI. PWM technique is employed to generate output voltage. The Simulation is done using MATLAB Simulink.
