The need of dc–dc switching converters for power supplies with high-voltage gains has increased in the recent years due to new applications in areas as renewable energy systems, transportation, industrial, medical, and others. A quadratic boost converter is a useful topology to obtain a step-up output voltage; however, a major drawback is the presence of a higher voltage stress over the active and...
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...
