Maidul Islam Md. Aman Khan Mohammad Ali Choudhury Electrical and Electronic Engineering, Bangladesh University of Engineering and Technology, Dhaka, Bangladesh AJEEE2016452 10.12691/ajeee-4-5-2 2016 8 23 2016 9 11 2016 11 24 The DC-DC converter find a wide scope in industries, telecommunication sectors, power electronics area, etc. Nowadays bi-directional converters have a higher end over them since the energy from the load during regenerative braking is fed back to the source, thus obtaining energy efficient system. A single topology that can provide Buck-Boost operation with positive output having four quadrant operations is not available in literature. A common limitation of power coupling effect in some known multiple-input dc-dc converters has been addressed in many literatures. In this paper, a new single-input DC-DC four quadrant Sepic converter has been developed to provide four quadrant operation of a high frequency dc-dc converter having one supply source and proper control of the converter. The combined topology has been analyzed and studied by spice simulation and Tecplot.
