    On-board Vehicle-to-Grid (V2G) integrator for power transaction in smart grid environment
    (Institute of Electrical and Electronics Engineers Inc., 2014) Koduri, N.; Hampannavar, S.; Yaragatti, R.Y.
    The growing oil demands and the economic concerns have inspired the governments, car manufactures and the environmentalist to promote the manufacturing of Electrical Vehicles (EV). With developments in the power grid and advancements in the vehicle technology the EVs can contribute to the grid by selling or buying power from the grid. For the effective and efficient use of the V2G there is a major scope to develop the V2G integrators like On-Board and Off-Board. In this paper the On-Board V2G integrator is proposed and is modeled using MATLAB/SIMULINK. The conversion efficiency of 90% is obtained and the benefits of V2G are listed. © 2014 IEEE.

    High-gain DC-DC converter with zero input ripple current : Design and Analysis*
    (Institute of Electrical and Electronics Engineers Inc., 2023) Mishra, S.; Shetty, S.; Vinatha Urundady, U.
    In this paper, a non-isolated high-gain dc-dc converter that utilizes switched-capacitor and switched-inductor (SC-SL) network is proposed and thoroughly analyzed. The proposed topology features a single switch and less number of passive elements as compared to recently emerged high-gain converters. The mathematical analysis of the proposed converter is carried out to find the converter voltage gain and stresses on power devices.The converter achieves a gain of nine times at 50% duty cycle with comparatively less voltage stress on power devices. Additionally, the converter encompasses the current mirror ripple cancellation circuit (CMRCC) to eliminate input current ripples. The converter is modelled and verified in continuous conduction mode(CCM) using MATLAB/SIMULINK. The obtained findings exhibit that the input current ripples are effectively eliminated by the CMRCC implementation. © 2023 IEEE.

    Compact Single-Inductor Dual-Input Boost Converter Design for EV Applications
    (Institute of Electrical and Electronics Engineers Inc., 2025) Koushik; Naik, S.; Moger, T.; Jena, D.
    This paper introduces a new non-isolated DC-DC converter designed for electric vehicle (EV) applications. The existing topologies consists of many components, leading to increased conduction and switching losses. This results in lower efficiency and more complex control, which ultimately reduces the overall performance of the converter. The proposed converter is compact, efficient, and uses fewer components, making it suitable for systems with space and cost constraints. Detailed analysis, including steady-state and small-signal modeling, is carried out to ensure reliable performance under different conditions. A stable controller is designed using the K-factor method. The design is tested using MATLAB/Simulink simulations in both open-loop and closed-loop setups to study its performance, efficiency, and response. The results are further verified through hardware-in-the-loop (HIL) testing with OPAL-RT, linking the theoretical design to practical implementation. © 2025 IEEE.
