Summary In this paper, a pulse width modulation DC‐DC converter with high step‐up voltage gain is proposed. The proposed converter achieves high step‐up voltage gain with appropriate duty ratio, coupled inductor, and voltage multiplier technique. The energy stored in the leakage inductor of the coupled inductor can be recycled in the proposed converter. Moreover, because both main and auxiliary switches can be turned on with zero‐voltage switching, switching loss can be reduced by soft‐switching technique. So the overall conversion efficiency is improved significantly. The theoretical steady‐state analyses and the operating principles of the proposed converter are discussed in detail for both continuous conduction mode and discontinuous conduction mode. Finally, a laboratory prototype circuit of the proposed converter is implemented to verify the performance of the proposed converter. Copyright © 2015 John Wiley & Sons, Ltd.
