摘要/Abstract

摘要：

以反馈系数K为参数，研究线性模式开关电容DC-DC变换器的非线性行为并得到分岔图．当反馈系数比较大时，系统出现混沌现象．基于减小反馈系数、提高稳定性的思想，提出了在基准电压输入端添加基准电压调整模块的拓扑结构，增加的基准电压调整模块由两级运放组成．分析了增加基准电压调整模块前后变换器的反馈系数，并对其进行了仿真，得到了输出电压的时域波形和相图．仿真的结果表明，所加入的基准电压调整模块能有效地抑制混沌现象，改善系统的稳定性．

Abstract:

This paper studies the bifurcation and non-linear dynamic behaviors of the linear-mode switched-capacitor DC-DC converter with the parameter K and the fact that the system appears chaotic when the feedback coefficient is relatively large. In this paper we propose converter topology by increasing a reference voltage regulator module in the reference voltage input, which improves the system stability. The reference voltage regulator module consists of the two stage amplifier. In this study, the feedback coefficients of the converter with and without the reference voltage regulator module are analyzed, respectively. The output voltage of the time-domain waveform and phase diagram are obtained through the simulation Simulation shows that the reference voltage regulator module added can effectively suppress the chaos and improve the system stability.

Key words: linear-mode, switched-capacitor DC-DC, chaos control
