Analysis of Interleaved Series Capacitor Tapped Buck Topologies for Adjustable Output Voltage Range

During the last decade, high step-down applications have become an emerging topic in power electronics. From delivering power to modern embedded systems, to improving efficiency in high current and low voltage appliances, such as welding machines or superconducting magnets. In this work, an analysis of the series capacitor buck, one of the novel topologies in this field, is presented with two different configurations of tapped-inductors, in order to allow for a more flexible output voltage range.
