Abstract

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
