Investigation of Multiple-input Multiple-output Switched-capacitor Converters

The power conversion circuits are essential in most of the electronic systems. In fact, the power converter is considered the bottleneck towards miniaturized microsystems. Switched-capacitor converters are subset of switching-mode converters and they are competitive candidate due to their inductorless structures. The design and implementation of SC converters are thoroughly studied in the literature but limited to single-input single-output (SISO) structures. This research aims to investigate the design limits of multiple-input multiple-output (MIMO) switched-capacitor (SC) converters. This proposal is to develop a generic model for MIMO SC converter based on the generalized fundamental limit theory of the SC converter. Circuit prototypes for various power levels will be designed, simulated and experimentally tested to verify the generalized model of the MIMO SC converters. Upon completing this study, the generic model will serve as a foundation in designing high efficient and area-optimized conversion units.
