This dissertation explored the ideas and concepts for hybrid switched capacitor converter topologies and new power delivery architectures to provide viable solutions for high conversion ratio DC-DC and AC-DC applications.A new Multi Inductor Hybrid (MIH) Converter family for high conversion ratio DC-DC applications has been synthesized and analyzed to provide non-isolated DC-DC conversions with large voltage conversion ratios efficiently. The highlight of this converter family is a 6-level 6-phase 6-inductor MPMIH converter, which achieved 90.7% peak efficiency with a load range of 0-220A at 1V and 1kA/in.

3 density.A new modeling method reveals that all odd-level Flying Capacitor Multi-Level converters become current sources with non-ideal timing while the even-level converters stay as voltage sources. A method for identifying unbalanced hybrid converters is also provided.This dissertation …
