    A Non-isolated Step-up DC-DC Converter Based on Modified Quadratic Boost and Cuk Converter
    (Institute of Electrical and Electronics Engineers Inc., 2024) Mandal, S.; Prabhakaran, P.; Adib, M.
    This paper presents a novel non-isolated high-gain DC-DC converter engineered for optimal efficiency. This converter boasts a remarkably simple structure and employs a minimal number of components. Its standout characteristic is its wide duty ratio range, which significantly enhances adaptability to suit the diverse requirements of renewable energy sources (RES) and electric vehicle (EV) applications. The proposed converter integrates the quadratic boost and modified Cuk converter designs to obtain enhanced gain and performance. Additionally, this converter offers the advantage of utilizing just one switch, leading to simplified circuitry and reduced complexity. Furthermore, the voltage stress across the switch is maintained at a low level, contributing to improved reliability and reduced cost. A brief analysis and simulation results are presented to validate the efficacy of the proposed converter. © 2024 IEEE.

    Extending the ZVS Range of Phase-Shifted Full-Bridge DC-DC Converters with a Variable Inductor
    (Institute of Electrical and Electronics Engineers Inc., 2024) Adib, M.; Sadeghian, S.; Talebi, N.; Prabhakaran, P.
    The objective of this study is to introduce a novel method for extending the soft-switching range of Phase-Shifted Full-Bridge DC-DC converters. Although these converters are renowned for their high efficiency, they face challenges in maintaining soft switching across a wide load range. The proposed approach incorporates a variable inductor, controlled by a low-power DC excitation, to reduce the current on power switches during mid- to full-load conditions and ensure adequate current to maintain soft switching under light-load conditions. Both the practical implementation of the variable inductor and the simulation of the converter confirm the feasibility of the proposed design. © 2024 IEEE.
