Non-Isolated Single-Switch Zeta Based High-Step up DC-DC Converter with Coupled Inductor

In this paper, a non-isolated high step-up DC-DC converter has been proposed for renewable energy applications. The proposed structure converter has been derived from the fundamental Zeta converter, in both of which only a single switch is employed. The voltage gain ratio has considerably enhanced in this converter with the absence of using switched capacity. To magnify voltage gain of the converter, a coupled-inductor has adopted. Increase and decrease of gain by changing the ratio of coupled-inductor assist the duty cycle. The number of components is low in this structure. The operating principle and evaluation of the proposed converter, considering designing approaches for elements, are discussed in detail. To verify the feasibility of the proposed converter, simulation results have been provided and evaluated.
