This study proposes a new hybrid non-isolated DC–DC converter suitable for photovoltaic applications, which can be extended to other applications such as electric vehicles, fuel cells etc. The proposed converter combines the main characteristics of boost and Ćuk converters with a coupled inductor, voltage multiplier, and super-lift cell. Additionally, the proposed topologies present reduced voltage stress across the semiconductors when compared to similar converters and high efficiency. Experimental results obtained using a laboratory prototype (35 V/400 V and 200 W) validate the efficacy and viability of the proposed topology.
