| 摘 要： | 提出了断续工作模式(DCM)下Boost变换器的能量模型,通过比较基于此能量模型下PWM Boost变换器的输出电压与参考文献中的结果,证明了此能量模型的正确性.基于脉冲跨周调制(PSM)Boost变换器的能量模型,分析了DCM模型下变换器的稳定性;理论分析与住址结果表明DCM模态下的PSM变换器不会出现混沌现象,但会出现分岔现象,且分岔吴现特定规律.文中还给出了PSM Boost变换器的分岔规律及负载电阴的边界条件.

| Abstract: | The energy model of Boost converter in discontinuous conduction mode (DCM) is proposed in this paper. Comparing the output voltage of PWM converter based on the presented energy model and those in reference papers, it is proved that the energy model is correct. The stability of PSM converters is also analyzed based on the energy model. According to the deduction and simulation, it is shown that although bifurcations are also happened for PSM converter, chaos will not be occurred for PSM converter in DCM. Mo... |
