“…Short-time Fourier Transform (STFT) is the most widely used linear method. It with fixed resolution and its resolution is low, which cannot take into account both high-frequency information and lowfrequency information [23]- [24]. But the Wigner-Ville distribution has high resolution, and it can clearly describe the energy distribution of the signal in the time-frequency plane, so its application is increasing in recent years.…”

In order to analyze the bifurcation and chaos of Superbuck converter in Continuous Current Mode (CCM), a new method of time-frequency diagram based on Wigner-Ville distribution is proposed. The method is used to analyze the variation of the energy component of the output voltage with frequency and time. It reveals that the Superbuck converter exhibits period-1 bifurcation, period-2 bifurcation, period-4 bifurcation and chaos under different reference current. The results of the time-frequency diagram are consistent with the results of the bifurcation diagram, time-domain diagram, phase diagram and Poincare section. It proves that the method can deeply understand the nature of bifurcation and chaos in Superbuck converter, and it provides a new way to analyze the nonlinear phenomena of DC-DC converter

Background: Superbuck converter as a strong nonlinear system, with the change of parameters Superbuck converter performance may be reduced due to nonlinear phenomena, such as bifurcation, chaos. Objective: Analyzing and controlling nonlinear phenomena in current-mode controlled Superbuck converters. Method: Bifurcation diagram, time-domain waveform diagram, phase portrait and poincare section. are used as analytical methods for the nonlinear dynamic characteristics of Superbuck converters. The chaotic control method of Superbuck converter is Resonant Parameter Perturbation (RPP). Results: After applying RPP control to the Superbuck converter in the chaotic state, it is converted into a single-cycle stable state in about 0.4ms. After the converter is controlled, the output current ripple is reduced from 0.71479A to 0.31A, and the output voltage ripple is reduced from 3.905V to 0.679V. Conclusion: With the increase of the reference current or the decrease of the input voltage or the increase of the load, the system enters the chaotic state through the period-doubling bifurcation path. In this paper, the chaos control of Superbuck converter is carried out for the first time, and the control method is the resonant parametric perturbation method. After RPP control, the converter is changed from unstable chaotic state to stable period 1 state in about 0.4ms.
