    Abstract: This research proposed an improved passive control method based on passive delay feedback control to solve the unpredictability bifurcation phenomenon of Buck converter in intermittent conduction mode due to the sensitivity of load parameters. It constructed the discrete iterative mapping mathematical model of Buck converter under pulse width modulation strategy to analyze the generation mechanism of nonlinear bifurcation behavior. In addition, this paper introduced a passive delay feedback control strategy to replace the traditional proportional integral vector control for suppressing the strong stochastic bifurcation. Besides, it introduced an exponential optimization channel to form an improved passive feedback control for optimizing the dynamic response and improving the waveform quality of the system. Furthermore, this study built the physical topology simulation model of the Buck converter based on the MATLAB/Simulink simulation platform to verify the bifurcation suppression. It also designed different working conditions to check the system characteristics under multiple situations.The simulation result shows that the converter system under the improved passive feedback control not only has the anti-interference ability to suppress the bifurcation behavior, but also could make the system output high-quality electric energy with good waveform quality.
    Key words: Buck converter; intermittent conduction mode; bifurcation phenomenon; improve passive delay feedback control
