Abstract

In this paper, a novel interleaved high step-up (HSU) converter is presented. The proposed converter features a large voltage gain and common input-output grounding. In this interleaved HSU converter, by using only one zero voltage transition (ZVT) auxiliary circuit with one auxiliary switch and low number of elements, soft switching (SS) performance for all the semiconductors over a wide range of load variations is achieved. This leads to advantages of high efficiency and low complexity, expense, and size. The characteristics of the proposed converter are compared to similar state of the art converters, and to confirm its effectiveness, the simulation results of the proposed converter are presented.
