New Quadratic Sepic Converter with a Switched-Coupled Inductor

This paper presents a novel very high voltage gain DC-DC converter. Quadratic SEPIC converter incorporated with switched-coupled inductor. The leakage energy of coupled inductor is transferred to the load. The study analyzes operation of the proposed circuit in continuous and discontinuous regimes and determines the boundary between the operation modes. The theoretical expectations are confirmed by the experimental results.
