Abstract

A generic behavioral average-circuit model that analyzes hybrid converters that include a switched inductor and switched capacitors is developed. The model can be used to calculate or to simulate the average static, dynamic and small signal responses of hybrid converters. The model is valid for all operation modes of the Switched Capacitor Converters operating in CCM and DCM modes of the Switched Inductor Converter and is compatible with circuit simulators that include dependent sources. The model was verified by simulation and experimentally. The experimental converter included a Boost converter followed by x3 switched capacitor converter. Good agreement was found between the behavior of the proposed average model, full circuit simulation and experimental results.
