Item Single Inductor Dual-Input Boost DC-DC Converter for Electrical Vehicle Applications(Institute of Electrical and Electronics Engineers Inc., 2024) Shetty, L.G.; Naik, S.; Moger, T.; Jena, D.The implementation of single inductor dual input boost dc-dc converter is discussed in this paper which is useful in Electric Vehicle(EV) applications. The circuit is compact and have a limited number of components. The proposed converter has potential to be advantageous due to its simple form, good voltage amplification ratio, and comparatively greater efficiency. The steady-state analysis is studied in detailed. The required transfer functions were generated from a thorough dynamic study of the converter based on the converters small signal model. The simulations are done using the MATLAB/Simulink environment. The results are validated with the Hardware in Loop (Opal-RT). © 2024 IEEE.Item Comparative Analysis of Multi-Port DC-DC Converters for Electric Vehicle Applications(Institute of Electrical and Electronics Engineers Inc., 2024) Naik, S.; Shetty, L.G.; Jena, D.; Moger, T.To provide an adequate energy infrastructure for electric vehicles. Multi-port converters offer superior design and execution capabilities than single-port converters, making them particularly advantageous for Electric Vehicles(EVs), The non isolated multi-port dc-dc converter(MPC) topologies are employed in regulating the power distribution across various modules, including photovoltaic (PV) systems, fuel cells (FC), batteries, energy storage systems (ESS), and loads. In this paper few topologies, Multiinput Multioutput (MIMO) boost converter, Dualinput Dualoutput (DIDO) converter, Dualinput hybrid step-up converter(DIHDC), and Four-port converter(FPC), are studied. This will give a thorough analysis of each topology and a detailed performance comparison to aid in the complete under-standing of the benefits and downsides. This study compares a number of components, modes of operation, direction of power flow capability, and design aspects. The simulations study are carried out in MATLAB/Simulink, and are validated with OPAL-RT. © 2024 IEEE.Item Quadratic Switched Inductor-Capacitor Multi-Port Converter for DC Microgrid Application(Institute of Electrical and Electronics Engineers Inc., 2025) Naik, S.; Jena, D.; Moger, T.This article presents a Multi-Port Quadratic Switched Inductor-Capacitor DC-DC converter topology tailored for DC-microgrid applications. A Non-isolated Quadratic Switched Inductor-Capacitor Multi-Port Converter (QSICMPC) is proposed, and designed to integrate hybrid energy sources efficiently to generate the constant load voltage for DC-Microgrid. The cross-connected capacitors with output side inductor in the converter function as voltage doubler circuit, providing an additional voltage boost. Compared to existing converters, the proposed design requires fewer components while achieving a higher voltage gain. Furthermore, it features continuous input current, reduced diode voltage stress, and lower voltage ratings for passive components. The converter offers a wider voltage gain range and reduced voltage stress on power switches. This study highlights its operational modes and detailed steady-state analysis, and comparisons are underscoring the significance of the proposed design. © 2025 IEEE.Item Voltage Multiplier Cells Non-isolated Dual Input DC-DC Converter with Wide Voltage Gain for EV Charging Applications(Institute of Electrical and Electronics Engineers Inc., 2025) Naik, S.; Jena, D.; Moger, T.This paper will give Voltage Multiplier Cells based Non-isolated multi-port(VMC-NIMP) DC-DC converter utilizing a switched capacitor design which integrated with Hybrid energy sources based Photo voltaic (PV) -Fuel cell (FC) to EV charging applications. A non-isolated transformer-less Multi-Port DC-DC Converter is designed with the integration of hybrid energy sources. A voltage multiplier circuit will boost and improve the converter's gain. This design is having lesser ripples when compared to available converters. This has fewer components and a higher gain than the existing converters. This designed converter features a wider voltage enhancement, less voltage stress on the power switches, and a shared ground connection between the input and output terminals. This will gives operational modes, steady-state and comparison analysis to show the converter's importance in EV-Charging applications. © 2025 IEEE.
