Generic Average Modeling and Simulation of the Static and Dynamic Behavior of Switched Capacitor Converters

Abstract—A generic behavioral average circuit model of a Switched Capacitor Converter (SCC) is proposed and verified. The model is based on the average currents concept and assumes that each of the SCC subcircuits can be described or approximated as a first order network. The model can be used to calculate or simulate the average static, dynamic and small signal responses of the SCC. The model is valid for all operational modes of a SCC (complete, partial and no charge) and is compatible with any circuit simulator that includes dependent sources. Excellent agreement was found between the behavior of the proposed average model, full circuit simulation, and experimental results. I
