Analysis of soft charging switched capacitor power converters
… The focus of this thesis is to outline soft-charging control, which addresses the stigmas associated with switch capacitor converters. A topology analysis is performed to determine which topologies can support soft-charging, and the Dickson charge pump is selected for the continued …

High-performance power converters leveraging capacitor-based energy transfer
… loss can be eliminated by inductively charging/discharging the capacitors, a process called soft-charging operation. As a result, the capacitor size can be greatly reduced without reducing the efficiency. A general analytical framework is presented, which determines whether an arbitrary …

Architectures and circuits for low-voltage energy conversion and applications in renewable energy and power management
… efficiency. We explore the benefits of a new soft-charging technique that drastically reduces the major loss mechanism in switched-capacitor converters, and we show experimental results from a 5-to-1 V, 0.8 W integrated dc-dc converter developed in 180 nm CMOS technology. The use of power …

Closed Loop Control for a Piezoelectric-Resonator-Based DC-DC Power Converter
… through specific behaviors including PR soft charging, ZVS of all active switches, and all-positive instantaneous power transfer. However, closed-loop control of PR-based dc-dc converters is necessary for them to be practically viable. Implementation of this closed loop control is …

Analysis and design of high power density resonant switched-capacitor converters
This thesis is motivated by the desire for power electronics designers to create power electronic converters that have high energy density (are very small) and high efficiency (few losses). Switched-capacitor (SC) topologies that utilize the high energy density of capacitors are a candidate for …
