摘要

在设计和分析平均电流控制型功率因数校正(PFC)Boost变换器时

通常假设其工作在电流连续模式下

而采用电流连续模式下的平均模型分析变换器的动力学特性.而实际的变换器可能工作在电流断续状态

当变换器负载较小时

电流断续状态更加明显.因此

采用电流连续状态下的平均模型无法准确描述变换器的特性

尤其是混沌和分岔现象.本文采用考虑电流断续工作状态的状态空间模型

对PFC变换器中的低频分岔现象进行了分析

得到了低频分岔图

使该变换器由倍周期分岔到达混沌的路径更加清楚

使人们可以更全面理解这种变换器的动力学行为.并从分岔的角度分析了变换器的稳定性.其结果表明

变换器的输出电容和负载对变换器的稳定性具有很强的影响.通过给出的参数分岔图和二维参数与稳定性的映射图

为更好地设计变换器提供了指导.仿真分析结果和实验结果表明了本文所提方法的合理性和结果正确性.

Abstract

It is conventionally assumed that the average current controlled Power Factor Correction (PFC) boost converter operates in Continuous Conduction Mode (CCM)

and hence the average CCM model is used for analyzing the dynamics of the converter.In fact

the converter might work in Discontinuous Conduct Mode (DCM)

especially

in the light load condition.Therefore

the average CCM model cannot predict the dynamical characteristics accurately

especially bifurcation and chaos phenomena.The state space model

which covers possible DCM operation

is employed to investigate the low frequency bifurcation of the PFC converter.Low frequency bifurcation diagram is derived

which makes the route from period doubling bifurcation to chaos clear and makes a better understanding of the dynamics of the converter.The stability of the converter is investigated from the viewpoint of bifurcation

whose results show that the output capacitance and the load make great contributions to the stability of the converter.One dimensional bifurcation diagram and two dimensional parameters stability map give the hint to better understand and design the converter.The consistence of the simulation results and experiment results shows that the proposed method is reasonable and the results are correct.
