Behavioral Average Modeling and Equivalent Circuit Simulation of Switched Capacitors Converters
TLDR
In this paper, a behavioral average circuit model of a switched capacitor converter (SCC) is proposed and demonstrated by a unity conversion SCC, which can be used to calculate or simulate the average values of the SCC variables such as output voltage, capacitor voltages, and subcircuit currents.Abstract:
A generic behavioral average circuit model of a switched capacitor converter (SCC) is proposed and demonstrated by a unity conversion SCC The model is based on the average currents concept and can be used to calculate or simulate the average values of the SCC variables such as output voltage, capacitor voltages, and subcircuit currents The model is valid for all operational ranges of an SCC (complete, partial, and no charge) and is compatible with any circuit simulator that includes dependent sources Excellent agreement was found between full switched-circuit simulation, average simulation by proposed model, and experimental resultsread more
