摘要：
In this work, a complete study of the dynamical behavior of a class of switched-capacitor converters is carried out. The relationships between voltages, currents and duty ratio are given, as well as the corresponding ripples on the inductor currents and capacitor voltages that allow the proper selection of elements of the converter. The linear switching, nonlinear average and linear average models are derived. Transfer functions of possible variables to be used for control purposes are analyzed too. Experimental results in a 150 W converter are shown to verify the theoretical results given within.
