SARAVANAN, Subramani  and  RAMESH BABU, Neelakandan. A modified high step-up non-isolated DC-DC converter for PV application. J. appl. res. technol [online]. 2017, vol.15, n.3, pp.242-249. ISSN 2448-6736.  https://doi.org/10.1016/j.jart.2016.12.008.

A non-isolated high voltage gain DC-DC converter has been presented in this paper. The boost, SEPIC and modified SEPIC converters were analyzed and their performance was compared with the proposed converter. The proposed converter has been designed for the input voltage of15 V and an output voltage of 150 V with 100 W output power. The efficiency of the converter obtained was 92.5%, which is higher than that ofthe other converter models which were analyzed. Also, the proposed converter utilizes reduced input current and shows low switching voltaje stress. The time response analysis conveys that the proposed converter settles to the steady state voltage and current faster than the other compared converters.
