    A Nonisolated Enhanced Voltage Gain Dual Input DC-DC Converter with Symmetrical Bipolar Output
    (Institute of Electrical and Electronics Engineers Inc., 2024) Prasad, S.; Prabhakaran, P.; Arun Dominic, A.D.
    This paper introduces a novel four-port DC-DC converter designed for hybrid energy integration. The proposed non-isolated circuit topology provides a symmetrical bipolar output with enhanced voltage gain. It is specifically designed to interface Solar PV and fuel cells with a Bipolar DC microgrid, enabling single-stage energy conversion. The power converter features a simplified circuit structure with fewer components compared to existing high-gain multiport converters. Furthermore, it effectively controls inductor current and balances both pole voltages using a single set of controllers. A small-signal model is deduced for each operating state to facilitate the design of the control system. Steady-state and transient results are presented to validate the efficacy of the proposed circuit topology. © 2024 IEEE.
