While they are only capable of a finite number of conversion ratios, SC converters can support 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 efficiency. A complete, detailed methodology for SC converter analysis, optimization and implementation is derived. These methods specify device choices and sizing for each capacitor and switch in the circuit, along with the relative sizing between switches and capacitors.

This method is advantageous over previously-developed analysis methods because of its simplicity and the intuition it lends towards the design of SC converters. The strengths and weaknesses of numerous topologies are compared amongst themselves and with magnetics-based converters.

This design methodology is applied to three varied applications for SC converters.
