    A Non-isolated Bidirectional Buck-Boost DC-DC Converter with Minimum Component Count
    (Institute of Electrical and Electronics Engineers Inc., 2024) Mandal, S.; Prabhakaran, P.
    This paper presents a novel non-isolated high gain DC-DC converter designed to perform bidirectional buck boost operations in both the power flow directions efficiently. The converter is engineered with an emphasis on simplicity, utilizing a minimal number of components. Its standout feature lies in its broad duty ratio range, enhancing adaptability to meet the specific demands of renewable energy sources and electric vehicle applications. Noteworthy for its straightforward control and design characteristics, the proposed topology employs small signal analysis and the K-factor method for controller design. To rigorously validate the performance, open-loop and closed loop simulations of the proposed converter are conducted using MATLAB Simulink, considering a power level of 300 watts. This comprehensive examination ensures a thorough understanding of the converter's behavior and effectiveness in various operational scenarios. © 2024 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.
