Abstract :
A generic average model that is capable of predicting the static, large signal dynamics and small signal response of Switched Capacitor Converters (SCC) was developed and tested. The proposed model was verified by full circuit simulation and experimentally, and good agreement was found between the results. The model was used to study dynamic behavior of SCC systems including the small signal responses, which are required for designing control loops. The model can be of great design value as it can be used to optimize the dynamic design of SCC systems and to design the compensator for closed loop operation.
