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.Bipolar he microgrid (BDMG)dc-dc converterdynamic modelingfuel cell (Fe)high-gain convertermulti-input convertersolar photovoltaic (PV)
