Abstract

In this note we briefly reviewed literature on DC models focusing on losses associated with parasitic capacitor and switch resistances in switched-capacitor converters. We give topological formulas for equivalent output resistances in limit modes of operation. Next we propose an improved metric on output resistance in intermediate SSL-FSL mode, in the Minkowski distance form. Unified formulas have been derived with the use of the method of Incremental Graph. Illustrative numerical examples and PSPICE measurements are given.
