JEE_V8_N4_RevP1 Kamal Singh Kuldeep Sahay Journal on Electrical Engineering 2230 – 7176 8 4 34 43 Dc-dc converters, SEPIC converter This paper presents different topologies applied to the Single ended primary inductor converter (SEPIC) to obtain high static gain, and an overview of different types of converters. Nowadays, there is requirement of high efficiency in Dc-Dc converters for better performance of appliances. Hence, so many techniques are developed in order to increase the static gain of DC-DC converters for high efficiency and also high power solutions. New alternatives in SEPIC converter have been proposed for high and very high step-up ratio applications, which are based on new topologies known as modified SEPIC converters. These modifications give high static gain in comparison with the existing SEPIC converter and other classical converters. April - June 2015 Copyright © 2015 i-manager publications.
