dc.description.abstractHigh-gain non-isolated DC-DC converters are critical in renewable energy applications, but existing topologies often face challenges in modularity, common grounding, and input current minimization, limiting their scalability and practical implementation. This paper introduces a novel phase-scalable, interleaved high-gain converter derived from the quasi Z-source (qZc) structure, which connects qZs cells in parallel at the input and in series at the output. The proposed topology provides uniform interleaving, modularity, and common grounding, addressing key limitations of existing solutions. Analytical modeling, small-signal analysis, and control design are employed to implement a two-phase prototype, experimentally validated at 200 W. Results demonstrate stable operation over a 30- to 40-V input range, with a regulated 200-V output and reduced input ripple. The proposed architecture enables scalable voltage gain, reduced current stress, and simplified control for multi-phase expansion. These findings highlight both the novelty and practical applicability of the converter, offering a versatile solution for modern renewable energy systems.
