A contribution to the dynamic modeling of switched-capacitor converters

This paper presents an analysis of the dynamics of two particular DC-DC converters that have switched-capacitors; a DC-DC Three-Switch High-Voltage Converter and a DC-DC Single-Inductor Multiplier Cuk Converter. The purpose of this paper is to explain the dynamics of the parallel connection of capacitors during the switching states of the converters. The obtained large signal models may provide a detailed description of the converters presented in this paper. The mathematical description of several dynamics of these converters may be easily extended for a wide number of power electronics devices that present similar features. The contribution in this paper represents an advantage for dynamic analysis and control design for switched-capacitor-based converters.
