In this study, a modified DC–DC converter is proposed, which can achieve a high voltage-gain exploiting both quasi-Z-source and switched-capacitor networks. In addition to the high voltage-gain, the proposed converter has low voltage stresses on its elements. The steady-state analysis in both continuous and discontinuous conduction modes is given in this study. Moreover, the design of the passive elements, the calculation of the non-ideal voltage gain, and the power loss analysis are done. Then, an extended topology of the proposed converter is presented, which further enhances the voltage gain, while maintaining the voltage stresses of the components. A comprehensive comparison with the prior-art converters is performed to accentuate the advantages of the proposed converter. Finally, simulations and experimental tests are provided to substantiate the theoretical analysis.
