A new method for transformation to DC with significant gain in voltage for DC microgrid applications is presented. It is proposed to create a novel step-up converter topology that allows high- and low-power DC buses to maintain two different higher voltage levels. The technology maintains efficiency and has a lower footprint than traditional approaches because it uses fewer high-voltage capacitors. A thorough analysis of the converter’s functioning demonstrates its capacity to sustain constant voltage levels under a variety of loads. The proposed topology’s performance is verified through hardware implementation, and its effectiveness is demonstrated by simulation results. A comparative analysis further reveals that the inclusion of fuzzy logic control enhances the converter’s efficiency and stability. In general, this work advances the technology of DC–DC conversion for microgrid applications and renewable energy systems.
