A Design Methodology for Switched-Capacitor DC-DC Converters
Switched-capacitor (SC) DC-DC power converters are a subset of DC-DC power con- verters that use a network of switches and capacitors to eu000eciently convert one voltage to another. Unlike traditional inductor-based DC-DC converters, SC converters do not rely on magnetic energy storage. This fact makes SC converters ideal for integrated implementa- tions, as common integrated inductors are not yet suitable for power electronic applications. While they are only capable of a fnite number of conversion ratios, SC converters can sup- port a higher power density compared with traditional converters for a given conversion ratio. Finally, through simple control methods, regulation over many magnitudes of output power is possible while maintaining high eu000eciency.
