Switched LC Converter for Battery Backup Systems

Abstract

In view of obtaining converters with high voltage conversion ratio for applications like battery back-up systems. In this paper, such a converter is obtained by combining the passive and active switched inductor units. The symmetrical topology of the converter is analyzed and compared with conventional converters based on voltage gain, switching voltage stress and also inductor losses. The competency of this converter in a photovoltaic application to boost the output voltage using FPGA pulse is also analyzed and the results are presented.
