Analysis of Fifteen and Thirteen-Level Novel Cascaded Inverter Design Narmitha D, Karthikumar K, Chandrasekar P Ssrg International Journal of Electrical and Electronics Engineering, 2025 Purpose: This study aims to develop enhanced Cascaded Multilevel Inverter (CMLI) topologies for 15- and thirteen-level operation with a reduced number of switches, while maintaining low Total Harmonic Distortion (THD) and high efficiency for applications that include energy from renewable sources and Electric Vehicle (EV) drives. Design/methodology/approach: The proposed inverters employ asymmetric DC sources and a reduced switch architecture combined with novel Level-Shifted Pulse-Width Modulation (LSPWM). The system was modelled and validated using MATLAB/Simulink simulations to examine the output voltage quality, efficiency, harmonic performance, and switching loss. Findings: The simulation results confirm that the 13-level and 15-level inverter designs achieve efficiencies above 94% with significantly lower switch counts compared to those of conventional cascaded H-bridge inverters. The proposed topologies yielded THD values of 8.08% and 7.39% for 13- and 15-level inverters, respectively. The switching losses and voltage stress are condensed through the reduced-switch approach, resulting in a compact and cost-effective system Originality/value: Unlike typical CHB inverters, which need a significant number of switches and independent sources, the proposed architectures provide high-quality output with fewer components. A comparative analysis demonstrated that reduced-switch LSPWM-based designs improve the harmonic performance, efficiency, and cost-effectiveness. Therefore, they are appropriate for EV motor drives and Photovoltaic (PV) applications.
Efficient Energy Management System for AC–DC Microgrid and Electric Vehicles Utilizing Renewable Energy With HCO Approach S. Sruthi, K. Karthikumar, P. Chandrasekar Energy Storage, 2025 The reliability of various energy sources can be increased and distributed production and renewable energy can be fully integrated into the power grid on a wide scale through the growth and development of the microgrid (MG). Global energy difficulties are brought about by the finite supply of fossil fuels and the world's expanding energy consumption. Due to these challenges, the electric power system has to convert to a renewable energy‐based power generation system to produce clean, green energy. However, because of the unpredictable nature of the environment, the shift toward the use of renewable energy sources raises uncertainty in the production, control, and power system operation. This manuscript proposes a renewable energy‐based energy management system for electric vehicles and AC–DC MGs. The proposed method is Hermit Crab Optimizer (HCO). The major goal of the proposed strategy is to supply steady power regardless of generation disparity, which should stop the storage devices from degrading too quickly. The HCO approach provides a stable power balance for MG operation. The proposed technique efficiently strikes a power balance to meet load requirements and recharge electric cars. By then, the proposed strategy is implemented in the MATLAB platform and the execution is computed with the existing procedure. The proposed technique displays better outcomes in all existing systems like biogeography‐based optimization (BBO) algorithm, particle swarm optimization (PSO) algorithm, genetic algorithm (GA), and artificial neural network (ANN). The existing technique shows the cost of 25$, 30$, 35$, 40$, and the proposed technique displays the cost of 20$ which is lower than the other existing techniques.
An enhanced approach-based grid flexibility analysis for combined heat and power systems with variable renewable energy systems C Kalaivani, L Umasankar, Chandrashekhar Badachi, K Karthikumar Energy and Environment, 2025 An enhanced approach-based grid flexibility analysis for combined heat and power (CHP) systems with variable renewable energy systems is proposed in this article. The proposed system is the combined execution of White Shark Optimizer (WSO) and Pelican Optimization Algorithm (POA). The WSO approach updating behavior is enhanced by the POA approach hence named as enhanced WSO technique. The main purpose of the proposed technique is to provide the optimal grid flexibility by utilizing the CHP systems. Utilizing the proposed method, the demand for the sources is predicted in the year 2030. The proposed approach considers the optimization problem as a reduction of cost and analyzes the flexibility in both upward and downward directions. The sources like photovoltaic, wind turbine, hydropower plants, nuclear, and coal demand power are analyzed. Based on the seasons, the proposed approach analyzed the system flexibility. Finally, the performance of the proposed method is simulated in MATLAB/Simulink platform and the performance is compared to the various existing methods.
Power Saving Systems for Electric Vehicles Using Arudino and PWM Technology G. Sai Tejaswini, U. Geetha, M. Rishith, K. Karthikumar, P. A. Gowri Sankar International Conference on Electrical Energy Systems Icees, 2025 The increasing popularity of electric vehicles (EVs) demands the deployment of effective energy management systems to deliver better performance and sustainability. One of the most important challenges is reducing energy wastage with functional operation. The present research solves excessive power consumption by EVs through a solution offered by an Arduino microcontroller. The overall objective is to increase battery life and enable maximum energy distribution while ensuring functionality. The proposed system comprises real-time energy monitoring, power-saving-optimized operational modes, and intelligent power distribution by four relays—two for auxiliary systems (e.g., the light and fan), one for normal motor operation using an H-bridge, and one for the power-saving mode PWM-controlled motor switching. A variable duty cycle module enables the regulation of frequency and speed to ensure efficient running at low speeds. The originality of the solution is through the integration of innovative PWM-based control with Arduino-driven automation for maximum coverage distance with energy saving, and this makes a contribution to energy-efficient EV system design.
Explainable AI for Fault Localization in High-Voltage Electric Marine Propulsion Systems Sharada Prasad N, Aruljothi Kuppannan, K L Kishore, Saranya D, V V Satyanarayana Tallapragada, K. Karthikumar Proceedings 2025 International Conference on Recent Innovation in Science Engineering and Technology Icriset 2025, 2025 Electric marine propulsion systems that operate at high voltages are critical and fast failure diagnosis is needed aboard modern naval as well as commercial ships to ensure safety and less operational downtime. Traditional diagnotic approaches usually do not generalize well over complex fault conditions and black-box AI models do not provide the transparency required in areas of safety-critical performance. The proposed framework involves Graph Neural Network (GNN) with SHapley Additive exPlanations (SHAP) to achieve the interpretability of the fault localization. The GNN represents the propulsion system as a graph with a set of electrical components nodes and connections, allowing characterization of spatial and topological fault patterns. Unlike many other approaches, HAP analysis offers the intuitive explanation of features since the contribution of each signal between sensors to the diagnostic result is quantified. MATLAB/Simulink simulation analysis shows that the presented algorithm allows achieving high accuracy of localization and provides the marine engineers with actionable insights. The present work proposes explainable AI uses in marine engineering that addresses the gap between fault detection performance and interpretability by humans.
A new optimal space vector modulation with DTC switching strategy for induction motor control Ahmad Omar Deab, K. Karthikumar, Marimuthu Karuppiah, P. A. Gowri Sankar International Journal of Applied Power Engineering, 2024 Efforts to achieve swift and precise dynamic torque control have been central in AC drive research. Recent advancements in embedded computer systems have highlighted direct torque control (DTC) and field-oriented control (FOC) as key methods for enhancing torque dynamics, both utilizing space vector modulation (SVM) to optimize voltage source inverter positioning. This study introduces a novel synthesis by integrating DTC with SVM to address limitations in conventional DTC, which suffers from limited voltage vector availability, leading to undesirable torque behavior and significant current fluctuations. The primary goal is to develop an optimal switching modulator for the fastest torque response through the combined application of DTC and SVM. The proposed strategy optimizes DC bus usage, reduces torque fluctuations, minimizes total harmonic distortion in AC motor current, decreases switching losses, and ensures seamless digital system integration. Simulations using MATLAB/SIMULINK demonstrate significant torque, current, and flux linkage ripple reductions, validating the approach's effectiveness. This integration overcomes established limitations, extending the capabilities of motor control methodologies and offering enhanced performance and operational integrity in induction motor drive systems.
