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 …

Experimental results in a 150 W converter are shown to verify the theoretical results given within.
