Abstract:
      Owing to its high power density, high conversion efficiency, and suitability for large scale integration, high-frequency Boost converter has attracted more attention. However, because of its strong nonlinear characteristics, the system is more likely to generate bifurcation and chaos phenomena due to the improper parameter selection or external interference. In this paper, a stroboscopic map model of high-frequency Boost converter is established, and the variation of the Jacobian matrix' eigenvalues is used to judge the stability parameter domain of the system; in addition, the parameter bifurcations of the inverter are analyzed under different conditions. Through circuit simulations and experiments, it was found that the bifurcation and chaos phenomena in the high-frequency Boost converter were in agreement with the results of theoretical analysis. The conclusion in this paper can provide reference for the Boost converter to maintain stable operation under high-frequency conditions, and it also provides a theoretical basis for the system's further optimization design and control.
