Abstract

This article presents the effect of supply voltage variations on single-phase capacitor-clamped multilevel inverter-fed induction motor drives. This research is tailored at determining the best torque value and speed to attain a stable state under input voltage variation and minimum time response to realize low percentage harmonic distortions. The effect of constant power quality disturbance harms the performance and behavior of asynchronous motors based on harmonic contents and other energy source integrations. The multilevel inverter has shown good performance in motor drives. This paper deals with the effect of input voltage variations on a single-phase multilevel capacitor-clamped inverter for asynchronous induction motor drives. A five-level capacitor-clamped inverter with an in-phase disposition pulse width modulation technique is adopted. Four high-frequency triangular carrier signals are generated and compared with a reference sinusoidal signal. As a result of this approach, the inverter switches firing signals are generated. The open-loop model is designed and simulated utilizing MATLAB/Simulink and results based on different values of supply voltage are presented. The current and voltage total harmonic distortions (THDs) obtained are 4.97% and 4.46% respectively at the best operating voltage of 400 V and at maximum torque of 47 Nm.

Abstract

Now a days, many people use solar photovoltaic systems since they generate efficient and clean energy. Polycrystalline and monocrystalline silicon modules are currently the most widely used products in the solar industry. Aside from possessing a flawless lattice structure, a high level of material purity, a low grain boundary energy, a weak internal resistance, and a high level of efficiency, monocrystalline silicon cells also have a uniform colour and a lack of spots, which contribute to its good aesthetic appeal. By placing the solar panels at the precise angle and direction specified by the motion of the sun, the system's efficiency can be increased. The solar tracking system for this research project uses LDR sensors that are connected to a microcontroller to track the sun's horizontal and vertical axes, while DHT11 and rain sensors are used to track the weather. This study offers a method for repositioning a solar array so that it faces the sun at all times. Since solar modules effectively convert sunlight into electricity, they are helpful solutions to the problem of power generation in remote areas. A microprocessor is used in the construction of such a system to operate a motor and sensor.

Abstract

A novel microfluidic device and electronic infusion system for carbon nanotube-calcium chloride alginate microfibers are presented in this study. The microfluidic device was designed using Google SketchUp and 3D printing, and the electronic infusion system-controlled alginate solution flow to the calcium chloride jar—the silicon-PDMS microfluidic device produced calcium alginate microfibers with carbon nanotubes. The device to emulsify the two fluids was modeled in COMSOL Multiphysics. The microfluidic device and calcium chloride jar received juice from the syringe pump via a high-flow infusion pump (100, 150, and 200 rpms). Field emission scanning electron microscopes (FE-SEM), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, and X-ray diffraction analysis (XRD) detected highly concentrated microfibers with sizes from 10 to 100 um. I-V characterization showed that sodium alginate's carbon nanotubes at 5%, 6%, and 7% produced fiber sizes between 16.6 and 30 ums. Compared to pure alginate microfibers, those with carbon nanotubes and calcium chloride had higher mechanical strength and electrical conductivity. This study shows that the developed system can produce advanced microfibers with improved properties for various applications.
