Peak current controlled current-fed superbuck (CF-superbuck) converter is a higher-order converter, which has complex nonlinear dynamical behavior. The discrete iterative map model of peak current controlled CF-superbuck converter is established in this paper. Then, the bifurcation diagram of CF-superbuck converter is obtained by numerical simulation, which presents the evolution of nonlinear dynamics of the system. Finally, the time-domain waveforms of the inductor current and the capacitor voltage, and the corresponding phase diagrams are obtained from the circuit simulation and experiment. The result verify the nonlinear phenomena in this higher-order converter.
