An enhancement-mode aluminum gallium nitride (AlGaN)/gallium nitride (GaN) HEMT is presented in which graphene-capped SiN passivation, a recessed composite p-GaN gate, dual discrete field plates, and a compositionally graded AlGaN barrier (35%→18% Al) are co-engineered in a single device. The novelty lies in integrating these four techniques within one enhancement-mode architecture to simultaneously suppress surface trapping and reduce gate leakage, strengthen electrostatic gate control, and redistribute the electric field for higher breakdown and more uniform field profiles. TCAD results indicate a threshold voltage (Vth) of +2.6 V, transconductance (gm) of 335 mS/mm, and breakdown voltage (Vbr) around 1 kV. The radio-frequency (RF) analysis shows a cut-off frequency (fT) of ~42.57 GHz, with favorable gate capacitance characteristics. These outcomes show that co-optimization delivers normally-off operation with improved breakdown and RF speed relative to using the techniques separately, supporting suitability for high-power, high-frequency applications.

The advantages of multilevel inverters (MLIs) have led to their increased use in high- and medium-voltage power applications. These inverters reduce harmonic content, common-mode voltage, dv/dt stress on switches, and electromagnetic interference, among other things. In recent decades, drives for permanent magnet synchronous machines (PMSMs) that rely on inverters have become increasingly popular in both commercial and residential settings due to their great performance. Phase disposition (PD), phase opposition disposition (POD), and alternate phase opposition disposition (APOD) are three multi-carrier pulse width modulation (MCPWM) approaches that were simulated in this work to explore a 5-level DCMLI-fed PMSM. In order to create control pulses, each method compares reference signals with carrier signals that are either triangular or trapezoidal. Detailed comparisons with conventional three-level voltage source inverters (VSIs) are made based on the results. A 63.21 percent improvement in the total harmonic distortion (THD) of the output voltage and a 26.52% improvement in the THD of the stator current are both supported by experimental evidence.

10.11591/ijpeds.v17.i1.pp720-727

The need for efficient clean energy solutions has increased due to population growth, climate change, and the development of industries. Among these, the most valuable clean and sustainable alternative is solar energy, i.e., photovoltaic (PV) technology. However, the key challenge is represented by maximizing the PV systems' efficiency. This paper proposes an IoT-enabled single-axis solar tracking system for improving PV by constantly aligning solar panels with the trajectory of the sun. To achieve that, an Arduino microcontroller is integrated with light-dependent resistors (LDRs). LRDs perform real-time detection of solar irradiance in order to adjust along with the azimuth axis. Based on the experimental results, the IoT-enabled single-axis solar tracking system improves energy harvesting by comparing with fixed-tilt PV. The proposed system outperforms the fixed-tilt PV by 22.5% in daily energy yield and average power output. Furthermore, tracking efficiency is better than fixed-tilt PV by 96.3% and tracking error of 3.7%.

An efficient grid-connected solar PV system with a fault-tolerant mechanism to mitigate the voltage disturbances

10.11591/ijpeds.v17.i1.pp282-292
N. Jayakumar , B. Devi Vighneshwari , V. Prema
One of the most effective renewable energy solutions for long-term power generation is a solar photovoltaic (PV) system that is connected to the grid. However, power quality and system reliability can be significantly impacted by grid-side voltage disturbances such as sag, swell, and faults. To reduce voltage fluctuations and improve grid stability, this study proposes an effective fault-tolerant (FT) solar PV system coupled with a dynamic voltage restorer (DVR). The adaptive DVR-based control method, which dynamically injects compensatory voltages based on disturbance amplitude to ensure uninterrupted and distortion-free power delivery, is the feature that makes this study unique. MATLAB/Simulink is used to model and simulate the system to assess its dynamic response under fault, sag, and swell situations. IEEE 519 standards are met by the suggested design, which produces average total harmonic distortion (THD) values of 0.59%, 1.16%, and 1.55% for 50%, 100% sag/swell, and three-phase fault circumstances, respectively. This indicates that even in challenging grid situations, the DVR can sustain high-quality voltage profiles. For implementation in renewable-rich or weak grid networks, the suggested FT-DVR configuration provides a workable and affordable solution that guarantees better voltage regulation, less harmonic distortion, and increased operational dependability for upcoming smart-grid integration.

Optimizing battery safety and performance: Hardware implementation and simulation analysis of protective measures, SoC Measurement, and cell balancing in BMS

10.11591/ijpeds.v17.i1.pp383-393
Atul Kumar Singh , C. P. Boopathy
This paper presents a dual-platform validation of a compact battery management system (BMS) combining an Arduino-based hardware prototype and a MATLAB/Simulink model for cross-validation. The hardware implements over-voltage, over-current, and over-temperature protections, state of charge (SOC) estimation using open-circuit voltage (OCV) and coulomb counting (CC), and both passive and active balancing. Experimental results show that SOC accuracy remains within ±2%, active balancing achieves 57% higher energy efficiency and 37% faster convergence than passive balancing, and thermal rise is limited to <5 °C. Limitations include fixed protection thresholds and the absence of physical validation of long-term aging effects. The dual-platform approach allows cross-validation of hardware and simulation, benchmarking SOC estimation methods, and quantifying energy and thermal trade-offs between balancing strategies. This approach offers a low-cost and reproducible validation pathway for EV-oriented BMS design.

The paper presents a method for the coordinated tuning of automatic voltage regulation (AVR) and automatic speed control (ASC) systems for a group of generators operating in parallel at a power plant. The method also involves solving the optimization problem using a genetic algorithm. The possibilities of using lead-lag elements in AVR and ASC, which impart predictive properties and improve damping characteristics of the controllers, are also considered. A model of a power plant operating in parallel with an electric power system is presented. This model demonstrates effective damping of oscillations under large disturbances when the proposed method is used to adjust the AVR and ASC control coefficients, along with a self-tuning lead-lag element. In this case, voltage oscillations and frequency overshoot disappear, and there is a significant reduction in the maximum deviations of these parameters. In the illustrative case study, the coordinated tuning of the controllers provides a 6% increase in the transmitted power limit and, as a consequence, the enhancement of the stability margin of the electric power system.

Faruk Ahmeti , Dimitar Arnaudov , Sabrije Osmanaj
The use of renewable energy sources like solar photovoltaic, wind, and fuel cells is gaining popularity due to growing environmental awareness, technological advancements, and declining production costs. Power electronic converters are usually used to convert the power from renewable sources to match the load demand and grid requirements. Among these, DC–DC converters are essential for improving system functionality and power density, especially in low-voltage renewable systems that require high voltage gain. This paper presents a systematic evaluation of five advanced DC-DC converter topologies: multi-port DC, boost multiport interleaved step-up, isolated bidirectional, voltage/current fed, and general resonant focusing on their structural complexity, component count, and potential application scenarios. In addition, a novel high-gain three-port resonant A DC-DC converter is proposed, incorporating galvanic isolation via a three-winding high-frequency transformer. The converter adopts a half-bridge resonant inverter and rectifier-based load port, resulting in a compact and cost-effective solution. A detailed analysis of the converter's operation, design considerations, and control strategy is conducted using PLECS simulation. Furthermore, an experimental setup is developed to validate the converter’s practical feasibility. The setup schematic and comprehensive comparative tables are included to support the evaluation and highlight the proposed design’s capabilities.

Optimal speed control of SRM with integration of switching variable proportional desaturation fuzzy logic regulator for EV application

10.11591/ijpeds.v17.i1.pp58-68
Kadali Ravi Kumar , Narender Jatoth , Shaik Mohammed Mukassir
SRMs are recognized for their high efficiency, strong torque output, and capability to operate at high speeds, making them well-suited for electric vehicle (EV) applications. Their high initial torque effectively overcomes the vehicle's inertia during the drive mode, enhancing overall performance. Switched reluctance machines (SRMs) come in various structural configurations such as 8/6, 6/4, and 4/2, offering flexible options for different vehicle requirements. Speed control in SRMs is typically managed through current regulation, which is handled by a current controller. Traditionally, a proportional integral (PI) controller is used to generate the required reference current. However, the PI regulator is prone to high damping and sensitivity to disturbances, leading to increased speed overshoot during startup and longer settling times. To address these limitations, a switched variable proportional desaturation PI (SVPDPI) controller is employed. Nevertheless, due to its relatively slow response, the PI component in the SVPDPI is replaced with a fuzzy logic module to enhance controller performance. This results in a switched variable proportional desaturation fuzzy logic (SVPDFL) regulator, which significantly reduces initial speed overshoot and improves settling time toward the desired reference speed. This paper presents a comparative analysis of these controllers, with simulations conducted using MATLAB/Simulink to evaluate performance improvements.

10.11591/ijpeds.v17.i1.pp683-695
Ahmad Supawi Osman , Aidil Azwin Zainul Abidin
The integration of renewable energy systems (RES) and distributed generation (DG) into microgrids introduces significant challenges in maintaining voltage stability due to intermittent generation and reduced rotational inertia. This systematic review critically examines advanced control strategies aimed at enhancing voltage resilience in isolated RES-driven microgrids. Particular focus is placed on virtual synchronous generators (VSGs), which emulate electromechanical dynamics of synchronous machines via state-space modeling, and model predictive control (MPC), which enables real-time control optimization under multi-constraint scenarios. The review synthesizes literature on coupling–decoupling behavior, impedance sensitivity, and dynamic voltage response under varying load conditions. Additionally, it evaluates the role of hardware-in-the-loop (HIL) platforms and Runge-Kutta-based simulations in validating control models for real-time deployment. A structured framework is proposed, aligning VSG-based inertia emulation with predictive control to address voltage dips, oscillations, and transient instabilities. The findings highlight both theoretical gaps and implementation opportunities for achieving robust voltage stabilization in next-generation microgrids.

10.11591/ijpeds.v17.i1.pp107-122

This paper discusses a novel fuzzy adaptive sliding mode control (FASMC) strategy for a four-wheel-drive (4WD) electric vehicle (EV), incorporating an exponential reaching law (ERL) and a fuzzy adaptive switching gain to enhance speed tracking. The classical SMC technique often suffers from the chattering problem, which can degrade the dynamic control performance of the electric vehicle. To address these challenges, the proposed hybrid controller employs an exponential reaching law to ensure fast convergence and reduced chattering, while a fuzzy logic-adaptation mechanism dynamically adjusts the switching gain to improve robustness against uncertainties and external disturbances. First, the mathematical model of the motor derived for achieving speed regulation using the classical SMC with an exponential reaching law based on indirect-field-oriented control (FOC). Then, the proposed control technique is designed to automatically adjust the ERL gain using a fuzzy logic controller to ensure precise vehicle speed control, optimizing the vehicle's dynamics under varying road conditions. This novel configuration enables the development of a 4WD EV control framework with an optimized controller, serving as the foundation for implementing our proposed study. The results validate the proposed method's superiority, delivering lower chattering, enhanced tracking precision, and greater robustness compared to traditional SMC while adhering to control standards. This control framework presents a viable advancement for 4WD EV motion management, supporting safer, more effective autonomous vehicle technologies.

This paper presents a detailed study of developing a mathematical model and experimental analysis of electric drive processes in belt conveyors. The proposed model simplifies the complex real mechanical system by substituting distributed parameters, such as the transported load's mass and the traction element's elasticity, with concentrated equivalents. A comprehensive investigation of key transient processes including stator currents speed, torque and resistance forces was performed using MATLAB's Simulink environment. The findings reveal significant differences in performance between the initial startup phase and operation under loaded conditions. To validate the model's accuracy, the authors employed numerical analyses utilizing regression metrics such as root mean square error (RMSE) and correlation coefficients. The results show that the proposed model significantly outperforms similar models in the literature with a notable RMSE of 12.5 A for stator current, reflecting an 18% improvement and 8.7 Nm for torque prediction, indicating a 15% enhancement. Furthermore, the model achieved a correlation coefficient of 0.98, confirming its high accuracy in experimental data fitting. By effectively capturing oscillatory phenomena during both unloaded and loaded startup conditions, this work establishes the model as a reliable representation of belt conveyor dynamics, setting a new benchmark in the field.

This article addresses the design and manufacturing of two-speed asynchronous motors with pole-changing windings. The need for developing two-speed motors with a single pole-changing winding is justified from the standpoint of energy and resource efficiency, as well as improved starting performance of high-power electric drives. An analysis of existing pole-changing winding designs is presented, highlighting their practical limitations in industrial applications. A new pole-changing winding with a 4/2 pole ratio and 48 stator slots was developed using the discrete spatial functions method based on star–delta–double star configurations. The electromagnetic characteristics of the proposed winding were analyzed. Based on this design, a new 4A200L8/4U3 two-speed motor was manufactured and tested under production conditions at the energy motors plant. Experimental results show that at p1 = 4 pole pairs the motor delivers P2 = 20 kW with efficiency η = 87%, cos φ = 0.82, I1 = 43 A at slip s = 2.35%, while at p2 = 2 pole pairs it develops P2 = 36 kW with efficiency η = 91.5%, cos φ = 0.906, I1 = 66 A at slip s = 1.5%. The results confirm more efficient utilization of the active magnetic core at lower polarity and demonstrate the feasibility of implementing such motors for energy-saving applications in heavy-duty drives requiring two equivalent operating speeds.

MPC and FOC for LVRT performance in hybrid renewable energy systems

10.11591/ijpeds.v17.i1.pp405-413
Oday Saad Fares , Riyadh G. Omar , Kassim A. Al-Anbarri
This paper proposes a wind and solar energy-based hybrid generation system integrated with a photovoltaic (PV) array controlled using model predictive control (MPC) and a doubly fed induction generator (DFIG) wind turbine controlled using field-oriented control (FOC). The system employs cascaded-based and bridge-based structures for two renewable sources, and they are connected to an ordinary common load, and designed to meet the stringent conditions of low-voltage ride-through (LVRT) required during fault conditions and grid-side perturbations. In order to safeguard the power electronic converter from sharp voltage dips, a crowbar protection circuit is used on the rotor side of the DFIG. In order to verify the enhanced LVRT capability of the offered system, extensive modeling, control design, implementation steps, and numerous simulation results have been included. The use of sophisticated control methodologies and protective measures improves the reliability and stability of wind-solar power plants. Simulation results reveal that for a serious grid disturbance, the system manages to maintain the output voltage at 70% of its nominal value and keeps the waveform steady and sinusoidal. In addition, the control scheme ensures that the rotor current is not just sinusoidal but also well-balanced, yielding a steady-state electromagnetic torque. This combination of control and protective measures is paramount for achieving stability, power quality, and reliability in current hybrid renewable power systems.
