“…There are several modulation techniques used for switching the power device MLI. These include Pulse Width Modulation (PWM) [21,23,25,34], Voltage bala [11,33], Algorithmic-Controller-based PWM [37,38,[40][41][42], and Artificial-Intelli based Controller [30,35,39]. In this work, a model predictive control algorithm wa to predict the width and instance of the switching pulses based on a reference sine A model predictive control algorithm was used in this inverter, and its workflow picted below in Figure 3.…”

“…A suitable weight function is used to enhance balancing of the inverter. A zeta converter to regulate output from PV array and a level-shifted switching-based MLI inverter is discussed in [34], and it is found to give promising results for PV array. In [35], a unified power quality controller is proposed, and this model uses an MLI based on ANN and soft computing techniques for mitigating various power quality issues.…”

Renewable and distributed energy generation includes wind turbines, fuel cells, solar cells, and batteries. These distributed energy sources need special power converters in order to connect them to the grid and make the generated power available for public use. Solar energy is the most readily available energy source; hence, if utilized properly, it can power up both domestic and industrial loads. Solar cells produce DC power, and this should be converted to an AC source with the help of inverters. A multi-level inverter for an application is selected based on a trade-off between cost, complexity, losses, and total harmonic distortion (THD). A packed U-cell (PUC) topology is composed of power switches and voltage sources connected in a series-parallel fashion. This basic unit can be extended to a greater number of output voltage levels. The significance of this design is the reduced use of power switches, gate drivers, protection circuits, and capacitors. The converter presented in this paper is a 31-level topology switched by a variable switching frequency-based model predictive controller that helps in achieving optimal output with reduced harmonics to a great extent. The gate driver circuit is also optimized in terms of power consumption and size complexity. A comparison of the 9-level and the 31-level PUC inverters is carried out to study the impact of the number of levels on the total harmonic distortion. The simulation results depict that the total harmonic distortion (THD) for a nominal modulation index of 0.8 is 11.54% and 3.27% for the 9-level multi-level inverter (MLI) and the 31-level modified packed U-cell multi-level inverter (MPUC-MLI), respectively. The reduction in THD is attributed to the increased number of steps in the output when using the model predictive controller.

“…Based on the modulation technique used, the number of levels can be changed according to variation of the modulation index value. Azeem et al [14], introduced a single-phase seven-level packed u-cell (PUC) multilevel inverter was connected with a zeta converter for PV applications, using solar energy systems as power sources. In comparison to traditional systems, the developed system minimizes switching losses, THD, cost, and size while improving output waveforms.…”

<p>Overall harmonic distortion and losses will grow during an energy conversion process, while power stability will be reduced. Multilevel inverter technologies have recently become very popular as low-cost alternatives for a variety of industrial purposes. The design's minimal benefits include reduced component losses, decreased switching and conduction losses, along with enhanced output voltage and current waveforms. Also, a reduction of the harmonic components of the current and output voltage of the inverter are the most important requirements in multilevel inverters. A seven-level inverter design is presented in this paper that is simulated using MATLAB/Simulink. The inverter converts the DC voltage from three photovoltaic (PV) systems into AC voltage at seven levels. During an outage of one of the PV systems, the inverter will make a switching reduction and supply the AC voltage as a five-level inverter. The inverter’s total harmonic distortion (THD) when it performs as a five-level or seven-level inverter is 4.19% or 1.13% respectively. The modulation technique used is phase disposition via four carriers and a single reference signal at the fundamental frequency.</p>

“…In reality, the solar system poses many issues in terms of environmental conditions, initial high capital cost, low efficiency, etc. To eliminate these above issues, the efficiency of the solar cell system can be improved by applying methods such as a maximum power point tracking (MPPT) techniques [16,17], a solar power management system (SPMS) [18] and boost converter in [19,20] which can get the high efficiency with slight weight. Besides, we also need to choose the most suitaestble materials for manufacturing solar panels.…”

The recent use of rotary-wing unmanned aerial vehicles (UAVs) has gained significant interest and continuously been implemented since they are used across the world for civilian, commercial, as well as military applications. The drawback of UAVs is the fight-time due to the limited battery capacity. Therefore, energy harvesting (EH), captured energy from the ambient environment is one of the effective measures to prolong the flight time for UAVs. This paper proposes the hybrid EH system, which can simultaneously harvest power from solar and radio frequency (RF) energy sources to significantly improve the energy issues for endurance longer flight UAVs. A 7-stage voltage multiplier circuit of the stand-alone RF-EH system is designed and simulated in this work. The stand-alone solar harvester is a solar panel. The DC output voltage from both of two energy sources is passed through a DC-DC boost converter and stabilizer. Simulation results can be deployed to power for the battery of UAVs in practice.
