A novel uninterruptible DC-DC converter for UPS applications

Abstract

The authors describes a novel DC-DC converter that integrates a Cuk converter and a buck converter to deliver uninterruptible DC output power. This converter has the desirable features of a simple circuit and high efficiency compared with a standalone uninterruptible power supply (UPS). The circuit operation and analysis of the converter, together with experimental results from a prototype circuit, are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
