Comparative study of Dynamical Behavior in Capacitor Current Compensated V2-Controlled and Peak Current Mode-Controlled Buck Converters

In this paper, an advanced control topology, namely, capacitor current compensated V2 (CCC-V2) control, is implemented in a buck converter and compared with a conventional peak current mode (PCM) controller. The system’s reaction and coping mechanism with sudden changes in load resistance, input voltage, and reference voltage are investigated. Nonlinear behavior is also observed due to variations in these parameters over a wider range, and the bifurcation diagram is used to analyze the system’s response.
