Title: Design and Analysis of High Gain DC-DC Converter For DC Microgrid Applications

Abstract :

DC microgrids have gained popularity due to the integration of renewable energy sources like solar photovoltaics, supercapacitors, and fuel cells. A significant drawback is their low output voltage, necessitating an efficient intermediate converter to boost the voltage. High-Gain Bidirectional DC-DC Converters (HGBDC) are crucial in microgrids, renewable energy systems, and electric vehicles. Batteries are essential for providing reliable power to the load, and HGBDCs are widely used to interface energy storage batteries with the DC bus. The Adaptive Quasi-Oppositional Differential Migrated Biogeography Based Optimization (AQDMBBO) algorithm is used for a solar PV system's maximum power point tracking (MPPT) integrated with a single-phase grid. This algorithm simplifies implementation, ensures rapid convergence, and maximizes power extraction. The design of hybrid high-voltage gain converters is essential for overcoming the limitations of basic boost converters. A new arrangement of capacitor-inductor-diode (CLD) cells with a traditional boost converter provides high voltage gain, a common ground point, continuous input current, and low voltage stress, reducing control complexity and power loss. This work includes theoretical analysis, design considerations, and simulations in MATLAB/Simulink, validating the proposed topologies.
