        abstract = {This paper presents the design, analysis, and experimental validation of a high step-up, phase-shifted DC-DC converter based on a multi-cell forward topology. The proposed configuration employs three forward converter cells with inputs connected in parallel and outputs connected in series (IPOS). This architecture ensures intrinsic sharing of the high input current, thereby reducing component stress and improving thermal performance, while the series-output connection and transformer turn ratio collectively achieve a high static gain without requiring an extreme duty cycle. A phase-shift modulation strategy, implemented via a PIC microcontroller and gate-driver circuitry, is applied to the interleaved switches. This technique effectively reduces the magnitude of the current ripple output, enabling a significant reduction in the size and volume of the single output LC filter. A comprehensive steady-state analysis, including operational stages and the derivation of design equations, is provided. The performance of the converter is verified through a 1-kW laboratory prototype, converting 24 V DC input to 210 V DC output. Experimental results demonstrate stable closed-loop operation, confirm the current-sharing capability among the parallel cells, and validate the reduction in output ripple due to interleaving. The converter proves to be a compact and efficient solution, making it highly suitable for applications requiring high voltage gain from low-voltage sources, such as renewable energy systems, electric vehicle powertrains, and energy storage interfaces.},
