-This paper proposes a high step-up single-switch DC-DC converter, integrates voltage multiplier cell (VMC), voltage lift capacitor and coupled-inductor (CL) techniques to obtain a large conversion ratio. Utilizing a passive clamp circuit and also, with no requirement of higher duty cycle values, the suggested converter obtains a high voltage gain, low conduction losses, and reduced voltage stress of the semiconductors with steady value for whole range of duty cycle. In the paper, operation principle and steady-state analysis of the suggested converter are discussed in details. Moreover, a comparison study is performed to demonstrate the superiority of the presented converter over several similar recently proposed DC-DC converters. Finally, the validity of theoretical analysis is verified using experimental measurement results of implemented prototype with a power rating of 226 W.
