Abstract

With the rising adoption of electric vehicles (EVs) and renewable energy technologies, managing battery systems efficiently has become essential to ensure enhanced performance, reliability, and longevity of battery energy storage systems (BESS). One key technique in this context is active cell balancing, which ensures that all cells within a battery pack maintain consistent charge levels, thereby avoiding issues such as overcharging or deep discharging individual cells. However, conventional balancing approaches typically fall short when it comes to adaptability and responsiveness under varying operational conditions. To overcome these challenges, this research explores the integration of artificial intelligence (AI) methods into active cell balancing frameworks. By utilizing AI techniques including reinforcement learning, neural networks, and fuzzy logic, the system can learn and anticipate cell behavior, dynamically regulate balancing currents, and respond effectively to real-time changes. This intelligent balancing method enhances the uniformity of the state of charge (SoC), improves thermal management, and ultimately increases the overall efficiency and lifespan of the battery pack. Simulated outcomes and comparative assessments validate the superiority of the AI-based approach over traditional methods, pointing to its potential in shaping future intelligent battery management systems.

Abstract

Sorting plays a crucial role in various applications, including high-performance computing, image processing, and network systems. Traditional sorting algorithms are efficient in software but can be a computational bottleneck in hardware implementations. This paper laid out various sorting architectures like Odd-Even Sort, Bitonic Sort, and Odd- Even Merge Sort with a detailed overview of their area, power and performance metrics. A Scalable and Hardware- Efficient Bidirectional Hybrid Sorting of Odd-Even Merge Sort and Bidirectional Insertion Sort. These designs were created using Verilog HDL simulated in Cadence Incisive and synthesized in Genus. Proposed architecture reduces area, power, and delay by up to 1.63%, 3.68%, and 16.93%, respectively, over existing design. The comparison made in the analysis of these data indicates the effectiveness of the proposed methodology in terms of resource allocation as well as preservation of the high efficiency of the sorting operation, indicating its applicability in such systems where resource allocation is inadequate in the comparison mode applied.

Abstract

Harmonic distortion in power systems can lead to inefficiencies, equipment failures and operational risks. Generally, the high order harmonics are introduced in a system when the electricity is controlled by electronics. Traditional detection methods, such as Fourier and wavelet analysis, typically face challenges with real-time detection due to high computational demands. The harmonic measurements are conducted on Power Quality Analyzers, Harmonic Analyzers and numeric meters. This paper proposes a novel neural network-based approach for harmonic distortion detection, utilizing the pattern recognition capabilities of Artificial Neural Networks (ANNs). The proposed method is simple, cost effective and feasible.

Abstract

This study presents a metamaterial-based antenna that overcomes common constraints and provides remarkable performance for military and remote applications. The study investigates the use of metamaterials to create a unique antenna with amazing capabilities, such as increased connection, downsizing, and electromagnetic wave bending. The feeding mechanism of the antenna is a modified co-planar waveguide. Two orthogonally polarized modes are excited simultaneously, and two composite right- and left-handed unit cells for transmission lines are positioned perpendicularly to produce circularly polarized (CP) radiation. Advances in broadband internet, high-resolution imaging, and space exploration are made possible by this discovery. The Split Ring Resonator (SRR) is a crucial part of metamaterials; for best results in near-infrared and optical applications, its diameters must stay below the resonance wavelength. The features of nanoscale SRR in the visible and infrared spectrums are examined in this study. The HFSS EM simulator was used to model all of the presented designs utilizing electron beam lithography (EBL). Dimensions of 23.7 mm x 23.7 mm × 1.6 mm and a substrate dielectric constant of 4.4 are important requirements. According to simulation data, metamaterials show negative permeability and permittivity within a particular frequency range, which is consistent with analytical expectations. The radiation pattern of the antenna is dipole-like and omnidirectional in both the H-and E-planes.

Abstract

As a result of its current popularity, solar energy is linked to a network. The innovative interchangeable Jetter topology of this initiative, including SPWM and H-bridge inverters, is not very harmonious. The number of advanced sinus-PWM switching processes is 1/4, which is UPWM and BPW technology. The new optimized PWM labor mechanism is then thoroughly explained. In the proposed optimized PWM technology, as many switches have a fourth switch as traditional unipolar and bipolar PWMs. A practical forward control method, based on a clear, simplified PWM strategy, is created to improve the performance of rectification and inverter modes compared to traditional dual-loop control systems. Compared to unipolar and bipolar PWM, the simplified PWM method with the proposed forward control system is more efficient and has lower harmonic distortion. Furthermore, the simplified PWM operation proposed in inverter mode has a higher available basic output voltage (VAB) compared to unipolar and bipolar PWMs. By comparing the multilevel version with a sophisticated inverter, the extended inverter produces a sinus-shaped output voltage and power shaft shape, as it uses four switches instead of the six used by the multilevel inverter. When comparing how to switch between SPWM and UPWM, SPWM switching technology increases the efficiency of the inverter and at the same time reduces general harmonics. The PIC16F72A implemented a sophisticated inverter model and checked the results.

Abstract

The performance of a Three-Phase Matrix Converter (TPMC) under various fault conditions is simulated and examined in this research. The proposed high-frequency converter offers a compact and efficient alternative to conventional 50 Hz solid-state transformers (SSTs) by virtue of its capacity to increase or decrease the output frequency. The Three-Phase Matrix Converter allows power to flow in both directions and removes the need for large DC cables. The TPMC is controlled by Space Vector Modulation (SVM), and a single-phase matrix converter is compared using Sinusoidal Pulse Width Modulation (SPWM). A fault detection system is included to monitor and respond to abnormal conditions, such as open-circuit and short-circuit faults. MATLAB/SIMULINK is used to develop and verify the system, and the outcomes confirm that the converter and filter design work well in both ideal and flawed scenarios. This study is simulation-based, serving as a foundational step toward future experimental validation.
