However, DC-DC converters also have some problems, such as output voltage fluctuation, noise interference, etc., which will affect the safety and stability of the system in some application scenarios.In recent years, scholars have discovered the chaotic phenomenon in DC-DC converters, that is, under certain working conditions, the output voltage of the DC-DC converter shows chaotic characteristics. The discovery of chaos has brought new perspectives and ideas for the research of DC-DC converters, and also provided new solutions for the research of noise interference and other problems in DC-DC converters.This paper will start from the basic principle of DC-DC converters, introduce the working principle of DC-DC 精品文档---下载后可任意编辑converters and the reason for noise generation, and further explore the mechanism of chaotic phenomenon in DC-DC converters. On this basis, this paper will expound the research progress of chaotic control in recent years, and propose a scheme for improving the stability of DC-DC converters based on chaotic control.Keywords: DC-DC converter; chaotic phenomenon; chaotic control; stability improvement.
