A Novel Non-Isolated High Gain Bidirectional DC-DC Converter for Photovoltaics to Extract the Maximum Power

this research paper presents a novel, non-isolated, high-gain bidirectional power flow DC-DC converter (NHBDC Converter) designed for photovoltaic (PV) applications using solar energy. The converter employs a ground-referenced three-switch configuration, enabling bidirectional power flow and offering a bipolar DC bus with two outputs. This configuration effectively eliminating leakage currents. To enhance performance, the suggested converter integrates to connect the input and output inductors using magnetic cores, reducing input current ripple and improving power extraction by the solar PV system. The paper provides a comprehensive design methodology encompassing simulation studies, and efficiency measurements and gain of the bidirectional power flow converter. Furthermore, the converter’s performance is compared with existing DC-DC converters. By utilizing a Boost converter configuration in conjunction with the Incremental Conductance Maximum Power Point Tracking (MPPT) Algorithm, the feasibility and effectiveness of the proposed converter concept are demonstrated. This research contributes to the advancement of solar PV technology and presents a promising solution for more efficient and reliable power conversion systems.
