Macy, Benjamin Blake 2015-07-22T22:17:21Z 2015-07-22T22:17:21Z 2015-05 2015-04-27 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 fulfilling these two criteria. However, there are inherent limitations in conventional switched capacitor converters where a designer is required to make a trade-off between efficiency and capacitor energy density utilization. One way to overcome this obstacle is to utilize resonance in a SC converter. This work proposes a resonant, voltage step-up Dickson SC converter. A single inductor is utilized to achieve zero current switching of all transistors, which allows for high switching frequency and high conversion efficiency. A split-phase control scheme is used in order to eliminate the current transients associated with the Dickson SC converter and the resultant power loss. Employing these techniques, a Dickson SC converter prototype is implemented with GaN transistors. The converter is able to achieve high power density while maintaining high efficiency because of the control techniques that are employed.
