Abstract :
The goal of this paper is to derive the analytical stability boundaries for Ćuk converter and to highlight the joint impact of power stage passive components and current controller characteristics on the converter stability. Stability conditions are determined by means of a novel dynamic model of the Peak Current Controlled (PCC) Ćuk converter, taking into account the difference between the small signal ac components of the voltage across coupling capacitor and of the sum of input and output voltage. A reduced-order small model of PCC Ćuk converter is proposed.
