Abstract

In this paper, a new non-isolated high voltage gain DC-DC converter using a combination of the modified quasi Z-Source and switched-capacitor networks is proposed. The proposed DC-DC converter has an acceptable number of elements, but achieves the low voltage stresses for its semiconductors and capacitors. Moreover, the voltage gain of the proposed converter is significantly high at lower duty cycles compared to the prior-art converters. In addition, the steady-state analysis is given along with the passive elements design. Then, the proposed converter is compared with other converters to highlight its advantages and drawbacks. Finally, simulation results in PSCAD /EMTDC are given to validate the theoretical analysis.
