Abstract

This paper presents a novel AC UPS scheme with power factor correction, which offers excellent characteristics such as: sinusoidal input current, sinusoidal output voltage, fast regulation of the AC-mains, galvanic isolation and fast transient response. The proposed converter includes the off-on line concept, which avoids the continuous charging and discharging of the battery as it occurs in typical on-line UPS. Analysis and design considerations as well as simulation and experimental results are given in this paper
