Development of a New High Frequency Two Quadrant DC-DC Sepic Converter

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 the literature.  A common limitation of power coupling effect in some known multiple-input dc-dcconverters has been addressed in many kinds of literatures. In this paper, a new single topology of two quadrants DC-DC 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.
