This paper presents a stacked-topology resonant switched-capacitor (ResSC) dc-dc converter to achieve a high voltage conversion ratio. The topology can be generalized to any N-to-1 dc-dc conversion application with only a single inductor. Multiphase interleaving can be further employed to improve the ripple cancellation and reduce requirement for bypass capacitors. To enable a wide output range while...
Applications such as under-sea power prefer dc current distribution in a series cable connection instead of dc voltage distribution due to the long distance and cable loss. Power converter modules employed in these scenarios have a constant current input. In this paper, steady state analysis and unique design considerations are presented for the series resonant converter topology with constant current...
This paper evaluates three alternative topologies for a static compensator (StatCom), suitable to eliminate the negative-sequence currents in a railway system. The compensator is placed in a transformer substation, which feeds two separate sections of the catenary. The major requirements of this converter is to: (i) symmetrize the railway load as seen from the high-voltage side, (ii) control the catenary...
