The aim of this research is to establish the method of random switching control by which the switching noise spectrum is spread and its level is reduced. In this method, random signals are used to make switching period irregular. This results in the reduction of the peak level of the noise spectrum. A chaotic signal is used as a random signal.Several results are obtained as follows :1.The noise spectrum of the DC-to-DC converter with random switching control is analyzed and confirmed experimentally. The peak levels of higher-ordered harmonics of switching noise are reduced effectively by this method. The control method is applied to a inverter for a fluorescent lamp and a switched mode rectifier. The noise reduction of them are also observed experimentally.2.Design of a random signal generator is investigated. Effectiveness of a chaotic signal as a random signal shown through piecewise-linear Markov maps. The noise generator is easily realized by a switched-capacitor circuit.3.Unstable chaotic oscillation is abserved in a resonant switching converter when high-frequency disturbances penetrate into the converter. The phenomenon is analyzed and confirmed experimentally.

本研究的目的是建立一种随机开关控制方法，通过该方法可以扩展开关噪声频谱并降低其电平。该方法利用随机信号使切换周期不规则化。这导致噪声频谱的峰值水平降低。混沌信号被用作随机信号。得到了以下几点结果：1。对随机开关控制的dc - dc变换器的噪声谱进行了分析和实验验证。该方法有效地降低了开关噪声的高次谐波峰值电平。该控制方法应用于荧光灯逆变器和开关模式整流器。实验还观察了它们的降噪效果。研究了一种随机信号发生器的设计。通过分段线性马尔可夫映射显示混沌信号作为随机信号的有效性。噪声发生器很容易通过开关电容电路实现。谐振式开关变换器在高频扰动进入变换器时，存在不稳定的混沌振荡。对这一现象进行了分析和实验验证。
