Abstract

A systematic approach to compare capacitive DCDC converters regarding performance and cost is presented. All possible topologies for a 4:1 voltage conversion ratio are generated using an algorithm developed in this research. Selected topologies are implemented benefiting from GaN transistors. Experimental results over various operating conditions up to 36 V input, 4 A load and 2 MHz switching frequency confirm theory and simulation. Two uncommon topologies demonstrate superior cost and load performance. The parameter space supports various industrial and automotive applications.
