The issue of DC to AC inverters has gained interest due to the growing use and investment in renewable energy sources as a competitive power source. This paper presents efficient technique for producing an AC sinusoidal signal from DC power. The primary objective is to create a highly effective inverter that generates a pure sinusoidal AC signal with the least amount of overall harmonic distortion. MATLAB Simulink was utilized to develop and simulate an inverter for this purpose. Four asymmetric DC voltage sources and sixteen power switches are included in the inverter design in a [ 1:2:7:11]Vdc ratio to create an inverter with 43 levels (-21 to 21).The value output voltage of the single-phase 43-Level (THD-V)equal 0.70%,while a three-phase system's value are 0.63% .The main contribution is the establishment and demonstration of a sound methodology and model based on multilevel inverter with high power and reduce number of switch.

In recent years, multilevel inverters (MLIs) have emerged to be the most empowered power transformation technology for numerous operations such as renewable energy resources (RERs), flexible AC transmission systems (FACTS), electric motor drives, etc. MLI has gained popularity in medium- to high-power operations because of numerous merits such as minimum harmonic contents, less dissipation of power from power electronic switches, and less electromagnetic interference (EMI) at the receiving end. The MLI possesses many essential advantages in comparison to a conventional two-level inverter, such as voltage profile enhancement, increased efficiency of the overall system, the capability of high-quality output generation with the reduced switching frequency, decreased total harmonic distortions (THD) without reducing the power of the inverter and use of very low ratings of the device. Although classical MLIs find their use in various vital key areas, newer MLI configurations have an expanding concern to the limited count of power electronic devices, gate drivers, and isolated DC sources. In this review article, an attempt has been made to focus on various aspects of MLIs such as different configurations, modulation techniques, the concept of new reduced switch count MLI topologies, applications regarding interface with renewable energy, motor drives, and FACTS controller. Further, deep insights for future prospective towards hassle-free addition of MLI technology towards more enhanced application for various fields of the power system have also been discussed. This article is believed to be extremely helpful for academics, researchers, and industrialists working in the direction of MLI technology.

“…Beside the topological solutions, reducing THD of output voltage by generating proper switching pattern modulation is also a hot issue of research in MLIs [10], such as multi-carrier PWM [11], selective harmonic elimination pulse width modulation PWM [12], and space vector modulation [13]. Many studies have been performed to reduce the harmonics of the output voltage of a MLI [14]. Several modulation techniques have been reported to selectively eliminate lower order harmonics of MLIs staircase output voltage [15].…”

<span lang="EN-US">The inverter has been attracting researchers for their application in renewable energy. So far, multilevel inverter is considered as low distortion class, which produces multilevel output voltage imitating a pure sine waveform. However, the needs for free distortion of output voltage have been motivating to improve multilevel pulse width modulation PWM generation method. In this paper, the modified PWM technique is proposed to reduce the voltage total harmonics distortion (THD) of multilevel inverter. This modulation technique is then applied to control a single-phase threelevel neutral point clamped multilevel inverter (NPC-MLI). Grey wolf optimizer (GWO) algorithm is utilized to generate optimal amplitude and phase shift of modified reference signal. The GWO algorithm is then compared with other optimization algorithms such as differential evolution (DE), human psychology optimization (HPO), and particle swarm optimization (PSO) to evaluate their performance in harmonic minimization. The performance of the proposed work is validated through simulation and experimentation on a prototype. The results show that the modified PWM technique optimized with GWO can reduce THD on NPC-MLI output voltage.</span>
