N2 - 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.
