The resonant converters have attracted a lot of attention because of their high efficiency and low switchinglosses. This paper presents the analysis of a high voltage gain non-isolated step-up DC-DC convertertopology using resonant technology. The proposed converter configuration has reduced number of powersemiconductor switches compared to the existing isolated converter topology having four semiconductorswitches. The proposed topology employs capacitor-inductor-capacitor (C-L-C) resonant circuit configuration.The size of the proposed converter and the losses in the converter are greatly reduced. Both the converterswith resonant components are simulated in Matlab/Simulink platform to validate their performance. Thetime-domain simulation results demonstrate that the proposed non-isolated converter gives improved voltagegain compared to the existing two-stage isolated resonant DC-DC converter.
