本文的目的是研究功率因数校正Boost转换器在传统峰值电流模式控制下的分叉行为。该转换器工作在连续导通模式。通过计算机仿真进行的分叉分析揭示了一些选定参数的变化对转换器稳定性的有趣影响。结果用时间域波形、离散时间图和参数曲线图进行了说明。分析研究证实了由计算机模拟得到的结果。这样的分析可以方便地预测稳定边界，并便于选择参数值以保证稳定运行。
The aim of the paper is to investigate the bifurcation behavior of the power-factor-correction (PFC) boost converter under a conventional peak current-mode control. The converter is operated in continuous-conduction mode. The bifurcation analysis performed by computer simulations reveals interesting effects of variation of some chosen parameters on the stability of the converter. The results are illustrated by time-domain waveforms, discrete-time maps and parameter plots. An analytical investigation confirms the results obtained by computer simulations. Such an analysis allows convenient prediction of stability boundaries and facilitates the selection of parameter values to guarantee stable operation.
