Abstract
The paper proposes a novel transformer-less bidirectional DC-DC converter that achieves ultra-high gain and reduces voltage stress across components. This converter is based on modified SEPIC and CUK topologies, and its derivation, operating principle, and steady-state analysis are presented. The paper also includes dynamic modeling of the converter and the design of closed-loop controllers for voltage and current control modes. Detailed analysis and simulation results are provided to demonstrate the efficacy and performance of the proposed topology. Overall, this innovative converter offers a promising solution for high-efficiency energy transfer with ultra-high voltage gain in various applications. © 2023 IEEE.
