A novel multi-input high gain dc-dc converter is proposed in this paper to integrate various voltage-current characteristic sources. The proposed converter offers several key features, including improved voltage gain, continuous input current, reduced component count, independent control of power transfer from each input source, enhanced converter efficiency, and the ability to function even when one of the input sources is unavailable. This paper focuses on a detailed analysis of the proposed converter with two input sources. For the case of n = 1, the proposed converter utilizes eight components, including two MOSFETs. The steady-state operation of the converter is discussed, and the voltage gain is derived. The boundary condition between Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM) is determined. The impact of parasitic elements on converter efficiency and output voltage is examined, and a loss-breakdown analysis is presented. To validate the analytical performance of the converter, an experimental setup is implemented using a converter prototype with specifications of 1 kW, 350 V, 60 kHz and two input sources.
