Item A Four-Port DC-DC Converter for Hybrid Integration of Fuel Cell-Solar PV with Bipolar DC Microgrid(Institute of Electrical and Electronics Engineers Inc., 2024) Prasad, S.; Prabhakaran, P.; Arun Dominic, A.D.This article describes a novel non-isolated dual-input dual-output DC-DC converter designed for the hybrid integration of Fuel Cell and Solar PV into bipolar DC microgrid systems, enabling single-stage power conversion. Unlike existing non-isolated multiport DC-DC converters, the proposed design offers significant voltage gain with fewer magnetic components. By employing a set of deduced controllers, the proposed converter effectively regulates both inductor current and output voltage, while its symmetrical output structure naturally balances pole voltages. Additionally, the converter can operate as a single-input-dual-output system if either the Fuel Cell or Solar PV source is unavailable. The paper explores various operating modes and presents steady-state simulation results, highlighting the effectiveness of the proposed circuit. © 2024 IEEE.Item 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.
