Multiphase Fibonacci Switched Capacitor Converters

摘要

A simple algebraic approach to synthesize Fibonacci switched capacitor converters (SCC) is analyzed and the expected losses are estimated. The proposed approach reduces the power losses by increasing the number of target voltages. The synthesized Fibonacci SCC is compatible with the binary SCC and uses the same switch network. This feature is exceptionally beneficial as it provides the option to switch between the binary and Fibonacci target voltages, increasing thereby the resolution of attainable conversion ratios. The theoretical results were verified by experiments.
