Peak-Current Mode control of Hybrid Switched Capacitor Converter

In this paper analysis and controller design of a peak-current mode controlled higher order buck converter is presented. Various small-signal models valid up-to half of the switching frequencies, are developed using state-space averaging method, and then a step-by-step controller design procedure is described. The results of controller design and closed-loop analysis are illustrated through computer simulations. To validate the controller design and analysis, experimental observations of a prototype hybrid switched-capacitor converter are provided for 28 V applications.
