摘要

本文使用一个简单的电路模型来研究开关DC/DC变换器中观察到的“间歇”混沌和次谐波，该模型描述了一些弱杂散信号可能与变换器的意外耦合。研究表明，干扰信号的强度和频率是影响间歇行为类型和间歇周期的重要参数。给出了仿真和实验结果。

Intermittent chaos in switching power supplies due to unintended coupling of spurious signals

This paper studies the "intermittent" chaos and subharmonics observed in switching DC/DC converters using a simple circuit model that describes possible unintended coupling of some weak spurious signal to the converter. The study shows that the signal strength and frequency of the intruding signal are vital parameters that affect the type of intermittent behavior and the period of intermittency. Simulations and experimental results are presented.
