Abstract

Abstract : A novel high step‐up DC–DC converter with coupled inductors has been proposed. The proposed topology includes two coupled inductors, four capacitors, four diodes, and two metal–oxide–semiconductor field‐effect transistors. Two coupled inductors charge in parallel when the switches are on and discharge in series when switches are off. Additionally, for absorbing the energy of stray inductance, a regenerative snubber is used. In this way, the duty cycle of the power switches can vary in a wider range and the voltage gain is higher in comparison to most of the other coupled‐inductor‐based converters. The effectiveness of the proposed converter has been verified by various simulation and experimental results.
