This paper introduces a quadratic-based DC-DC converter with high voltage gain, specifically optimized for DC microgrid applications. The proposed topology offers several key merits, including enhanced voltage gain, reduced voltage stress on switching components, continuous input current, a common ground between the input and output, high efficiency, and synchronized switch operation. A detailed analysis is provided on its operational principles, steady-state characteristics, design considerations, and efficiency evaluation, along with dynamic modeling and control assessment. To emphasize its benefits, the proposed converter is compared with existing topologies. The effectiveness of the design is validated through experimental testing on a 200W prototype, operating with an input voltage of 20V and delivering an output voltage of 200V.
